Sat Jun 23 00:06:35 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * Version 1.3. * du.c (count_entry) [HPUX_NFS_BUG]: If the size of the file according to the number of blocks reported is twice or more than the size of the file according to the number of bytes reported, halve the number of blocks. Fri Jun 22 00:38:20 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * tac.c: Change +regexp to +regex for consistency with GNU find. * cp.c (copy_dir): Initialize 'ret' to 0. * cp.c (main), ln.c (main), mv.c (main), rm.c (main): Make -i override -f and -o, to be conservative about removing peoples' files. * mkdir.c (make_path), mkfifo.c (make_path): Don't try to stat "" or "/". * rm.c, rmdir.c, mkdir.c, mkfifo.c: Move code to remove slashes at the end of an arg from main to strip_trailing_slashes. * install.c (strip): Print error message if the `strip' program can't be run. * system.h (convert_blocks): Macro moved from du.c and ls.c. Take a second parameter indicating whether to convert to kilobytes or 512 byte blocks. * ls.c, du.c: Pass second parameter to convert_blocks. Thu Jun 21 01:19:28 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * ls.c (print_long_format): Use mode_string instead of filemodestring. * ls.c (print_long_format): Compare times as longs, not ints. (longdiff): Macro to compare two longs efficiently if sizeof int == sizeof long and less efficiently but correctly if they are different sizes. (compare_ctime, etc.): Use longdiff. * ls.c (decode_switches): Make -k not imply -s, to allow the summary directory size printed by -l to be in 1k blocks without having the size of each file printed as well. (convert_blocks): Provide for systems with a blocksize that is other than 512 or 1024 bytes. * du.c (main): Exit with status 0 normally. (convert_blocks): Provide for systems with a blocksize that is other than 512 or 1024 bytes. Wed Jun 20 01:46:09 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * cat.c (cat): If FIONREAD is available, only use it if it is supported by the filesystem that the file is on. * ln.c (do_link): Take out code to give an error if source and dest are the same file. The dubious usefulness of the special case to prevent 'ln x x' from removing 'x' (ln -i can be used instead) is not worth preventing 'ln x y' from failing the second time in a row, and appears to contradict POSIX anyway. Mon Jun 18 02:48:17 1990 David J. MacKenzie (djm at apple-gunkies) * ls.c (print_file_name_and_frills, length_of_file_name_and_frills, print_long_format): Allow 6 digits for i-number, not 5. Sun Jun 17 00:09:23 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * install.c (install_dir): Don't check whether "" or the root directory exists (the former fails on some systems). * system.h: Make inclusion of sys/file.h conditional on USG and _POSIX_SOURCE, not DIRENT. * chmod.c (change_dir_mode): Use xrealloc instead of free and xmalloc in case malloc already left extra room. (xrealloc): New function. * rm.c (clear_directory): Prevent buffer overruns. More efficient string handling. Don't skip rest of directory if continuing after finding circular inode. (xrealloc): New function. Sat Jun 16 01:45:42 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * argmatch.c (invalid_arg): Change order in which the items are printed. * ls.c: Add +tabsize (-T) option. Fri Jun 15 23:40:55 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * dd.c (scanargs): For ibs and obs, set C_HARDWAY. (copy): Use different buffers only if C_HARDWAY, not if blocksizes are the same, to ensure constant output block sizes. Wed Jun 13 23:56:20 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * savedir.c: New file from code in chmod.c, modified to prevent buffer overruns. * chmod.c (change_dir_mode), cp.c (copy_dir), du.c (count_entry): Use savedir. Thu Jun 7 03:52:02 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * system.h (ST_BLKSIZE) [!STBLOCKS_MISSING]: If st_blksize is 0 (as on pipe reads on some systems), use BSIZE instead. Define BSIZE as DEV_BSIZE if necessary. * Makefile, system.h, fileblocks.c: Use STBLOCKS_MISSING to control whether st_blksize and st_blocks are used. * Makefile, system.h, backupfile.c: Use DIRENT to control whether <dirent.h> is used. Sun Jun 3 20:26:19 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * cat.c (main): Add a variable to control whether the check for input file == output file is made, because no values of st_dev and st_ino should be assumed to be available for this purpose. Only do the check for regular files. * tac.c: Use bcopy instead of memcpy. Thu May 31 00:55:36 1990 David J. MacKenzie (djm at apple-gunkies) * fileblocks.c: New file. * du.c (blocks_to_kb): Replace with convert_blocks macro. (main): Recognize new -k option. (usage): Document it. * ls.c (nblocks): Replace with convert_blocks macro. * system.h (ST_BLKSIZE) [USG]: Use BSIZE from sys/param.h instead of having the user define BLKSIZE. (ST_NBLOCKS) [USG]: Use st_blocks from fileblocks.c. * head.c: Use longs instead of ints for file offsets, for 16 bit machines. * cat.c, chmod.c, cmp.c, cp.c, cp.h, create.c, dd.c, dirlib.c, du.c, head.c, system.h, backupfile.c, ln.c, ls.c, install.c, mkdir.c, mkfifo.c, modechange.c, mv.c, mv_dir.c, rm.c, rmdir.c, tail.c, tac.c: Optionally use ANSI C and POSIX header files.

MacKenzie (djm at albert.ai.mit.edu) * install.c: New file (from ../bin-src). * cmp.c: Change some ints to longs for 16 bit machines. (bcmp_cnt): Make char-pointer counting slightly simpler. * dd.c (copy): Don't count completely failed writes as partial writes. Make buffers unsigned. If blocking or unblocking, pad final partial buffer if necessary. * getversion.c: New file. * mv.c (main), cp.c (main), ln.c (main): Control backup types with getenv ("VERSION_CONTROL") and +version-control or -V. * cp.c (yesno), mv.c (yesno), ln.c (yesno): Stop reading if EOF reached as well as at newline. * backupfile.[ch]: Rename var `version_control' to `backup_type'.

Fix typo. * cp-aux.c (usage): Update message. * mv.c, cp.c: Remove code to conditionally use utimes instead of utime, since the extra resolution of utimes was not being used, the emulation overhead is probably insignificant, and utime is a standard function. * cp-hash.c: Fix up comments. Fri May 18 23:06:23 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * mv.c (do_move): Only make backup if dest file exists. Don't continue moving file if dest can't be backed up. * ln.c (do_link): Don't try to unlink dest if it was backed up. Don't continue moving file if dest can't be backed up. * system.h: Make SIGTYPE default to void if not defined. * modechange.[ch]: Rename struct and external functions to start with 'mode_'. * modechange.c (oatoi): Make static.

(do_link): Don't allow hard links to dirs (they are hard to get rid of -- rmdir and unlink don't do it), unless -d was given. (usage): Mention -d +directory option. * rmdir.c (main): Remove trailing slashes from args (added by shell file completion but the rmdir syscall can't handle them). * mkdir.c (main): Remove trailing slashes from args, for uniformity with rmdir (you can't do file completion on dirs that haven't been made yet . . .). * mv.c: Rename global var `nargs' to `args_left' to avoid conflict with undocumented BSD libc function (the new name is clearer, anyway). Tue Feb 20 17:09:19 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * dd.c: Use new global var `program_name' in error messages instead of hardcoded "dd". (main): Set program_name from argv[0]. * chmod.c, head.c, tail.c (main): Don't strip leading dirs from argv[0]. (basename): Function removed. * rm.c (main): Don't strip leading dirs from argv[0]. * cat.c: Change `argbad' from a char to a short, so it will work on machines with unsigned chars. Mon Feb 19 14:34:18 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * rm.c (main): Strip trailing slashes from each arg. Thu Feb 15 13:23:52 1990 David J. MacKenzie (djm at rice-chex) * Makefile [HPUX CFLAGS]: Add -DUTIMES_MISSING. Wed Feb 14 15:01:18 1990 David J. MacKenzie (djm at rice-chex) * Makefile (dist): Don't make a non-compressed tar file. * mv.c (do_move): Refuse to copy non-regular files across filesystems. Mon Feb 12 11:30:45 1990 David J. MacKenzie (djm at rice-chex) * ln.c (do_link): Check error return from unlink. Include errno.h. * du.c (main): Check error return from stat. (str_copyc, str_concatc): Don't return a value, since it is ignored. * cp.c (copy): Check error return from unlink and chmod. Fix typo in call to error. * mv.c (do_move): Check error return of fchmod/chmod and utime[s]. (rename): Check error return of unlink. * Makefile Definitions of preprocessor macros moved from cp.c and mv.c. HAVE_FTRUNCATE changed to FTRUNCATE_MISSING. * Makefile, dirlib.c: NEED_MKDIR changed to MKDIR_MISSING. * mv.c, cp.c: Change USG ifdefs to UTIMES_MISSING. Sun Feb 11 17:50:29 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * chmod.c (usage): Add yet another ellipsis. Sun Feb 11 16:41:30 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu) * cp.c (copy_reg): Use HAVE_FTRUNCATE to decide whether to use ftruncate(). (main): Use GETGROUPS_MISSING to decide whether to use getgroups(). [hpux || !USG]: Define HAVE_FTRUNCATE. [USG && !hpux]: Define GETGROUPS_MISSING. mv.c (rename): Put in #ifdef RENAME_MISSING not #ifdef USG. (do_move): Use FCHMOD_MISSING to decide whether to use fchmod(). [USG && !hpux]: Define FCHMOD_MISSING and RENAME_MISSING. Sat Feb 10 02:16:40 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * cmp.c (cmp): Rename `r' to `first_diff', and `x' to `smaller'. Remove unneccessary variable `c1'. If -l was given, increase `char_number' by the number of bytes read, after producing output, rather than by the offset of the first differing bytes, before producing output. Replace if-else-if constructions with case statements for clarity. (bcmp2): Rename `n' to `nread'. Fri Feb 9 10:25:03 1990 David J. MacKenzie (djm at rice-chex) * mv.c (movefile): Remove trailing slashes from FROM (some filename completion systems add them for dirs, and they cause the rename syscall to fail). Thu Feb 8 22:50:12 1990 Torbj|rn Granlund (tege at sics.se) * cp.c (copy_reg): Change error handling after lseek, since this is a fatal error. Also change error message to something more generally understood. * Handle files that end in a zero block on USG systems. * cp-aux.c (error): Use FATAL to recog fatal errs. Thu Feb 8 21:25:40 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * ln.c: Remove incorrect comment. * cp.c, cp-aux.c (usage): Change +dereference option to +no-dereference, since dereferencing is done by default and the option turns it off. Mon Feb 5 17:29:20 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * Version 1.0 released. * Move discussion of missing tail -r option from tail.c to README. Sun Feb 4 02:23:01 1990 David J. MacKenzie (djm at rice-chex) * Makefile: Note that _doprnt seems to be broken on the sparc. Get rid of separate defaults for USG and BSD because the distinction is blurry. Sat Feb 3 04:03:32 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * cp.c (do_copy, copy, copy_dir): Rename `new_structure' to `new_dst'. (copy): If unlink because of flag_force succeeds, make new_dst nonzero. Fix wrong comment. * mkdir.c, rmdir.c: Replace functions fatal, nonfatal, and nonfatal_perror with function error, and rename global var `status' to `errors'. Fri Feb 2 11:15:18 1990 David J. MacKenzie (djm at rice-chex) * rm.c (main): Recognize new -o option to attempt to override protection of unwritable files, bypassing the query while still providing error messages. (rm): Don't ask question if -o was given. (usage): Mention -o +override option. * chmod.c (main): Recognize new -d option to dereference symlinks, setting xstat to stat or lstat appropriately. (change_file_mode): Use *xstat instead of lstat. (usage): Mention -d option. * chmod.c (nonfatal_perror): Set `errors' to 1 instead of incrementing it. * mv.c (error): New function to print message and set `errors'. (do_move): Call error instead of fprintf and perror. (perror): Function definition (for USG) removed. (main): Use new global var `errors' for exit status. (Makefile): Mention that -DVPRINTF might be needed for USG. Thu Feb 1 15:50:12 1990 David J. MacKenzie (djm at rice-chex) * chmod.c (main): Use new global var `errors' for exit status. (nonfatal_perror): Increment `errors'. Wed Jan 31 18:59:03 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * ls.c (decode_switches, usage): Change -z option to -S (to sort by file size), removing the old meaning of -S (don't sort) since it will be wanted rarely enough that +sort=none will suffice. If I think of a good letter for it I might put the short option for it back. (fatal, error): Change type of arg1 and arg2 to char * from int. (decode_switches, xmalloc, xrealloc): Add casts to calls of fatal. * Makefile (mkdir): Had CFLAGS, wanted LDFLAGS. Tue Jan 30 00:48:46 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * head.c, tail.c, mkdir.c, rmdir.c, dd.c, ls.c: Start all error messages with lowercase, for consistency. * rm.c (rm, clear_directory): Use the existing global var `pathname' instead of passing the path to remove as an argument, so that if `pathname' is reallocated, the old copy of `pathname' does not have to be left around for instances of the rm function that have not returned yet, and eventually lost and never freed. (rm): Pass pointer to stat structure as arg to clear_directory. (clear_directory): Take a pointer to a stat structure as an arg. Copy the directory contents into two buffers before processing them, so excessive file descriptors are not consumed. Move the call to check_stack to after the new pathname has been constructed, so any error message printed by check_stack is accurate. (check_stack): Take an i-number instead of a struct direct * as an argument. Remove the check for 'this should never happen'. (stp_cpy): New function. * ls.c: Add -S +sort=none option to disable sorting of filenames. Remove long options that are redundant with +sort, +format, or +time to make the option set easier to comprehend. (decode_switches): Handle -S option. (sort_files): Handle case sort_none. (usage): Update message. Mon Jan 29 14:25:47 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * chmod.c (nonfatal_perror): Add arg for describing the circumstances in which the error occurred. (change_file_mode, change_dir_mode): Add new arg to calls of nonfatal_perror. (change_dir_mode): Add arg for results of stat on the directory. Read the directory into a buffer before processing its contents so excessive file descriptors are not consumed. (change_file_mode): Add new arg to call of change_dir_mode. (stp_cpy): New function. * rm.c (clear_directory): If errno is set after failed opendir, print the system error message. Fri Jan 26 14:03:12 1990 David J. MacKenzie (djm at hobbes.ai.mit.edu) * dd.c (pfatal_with_name): Add program name to error message, and rearrange message. (main, copy): Make error messages clearer. * rm.c (perror_with_name): Add an argument for describing the circumstances in which the error occurred. (rm): Add the new argument to perror_with_name calls. Thu Jan 25 15:11:16 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * ls.c (usage): Mention +format=long and +time=use options. * ln.c (do_link): Use lstat instead of access when testing for the existance of the target file, in case the target is a symlink. * dd.c (main, usage): Remove conv=debug option. gdb is more useful. * du.c (usage, main): Alphabetize the options. Wed Jan 24 10:34:27 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * dd.c, du.c, mv.c, rm.c: Change some functions' return types to void. * cp.c, cp-aux.c, cp-hash.c: Remove void casts and indent. * dd.c: Un-nest some statements, make comments into full sentences, indent. (copy): Add program name and explanations to perror messages. (pfatal_with_name): Print filename on stderr, not stdout. * cmp.c: Un-nest some statements, indent. (main): Change an error message. * dirlib.c: Make compilation conditional on NEED_MKDIR instead of USG. * Makefile: Document NEED_MKDIR. * rm.c (clear_directory): Account for '/' and '\0' when checking whether length of `pathname' is sufficient. Mon Jan 22 00:32:09 1990 David J. MacKenzie (djm at albert.ai.mit.edu) * README: New file. * Makefile: Include README in distribution. Sun Jan 21 00:40:56 1990 David J. MacKenzie (djm at hobbes.ai.mit.edu) * system.h [USGr3]: If DIRSIZ is already defined, don't redefine it. * Makefile: Add linking rules for cat, cmp, du, head, ln, mv, and tail, for the sake of old makes that don't understand ".c:" default rules. Alphabetize the linking rules. Add INSTALL macro for program to install binaries in BIN directory. * cat.c, cp.c, du.c, ln.c, ls.c, mv.c: Remove declarations of alloca; already done in system.h. Tue Jan 16 23:10:17 1990 David J. MacKenzie (djm at rice-chex) * Makefile: Fix a couple of typos. Mon Jan 15 01:22:31 1990 David J. MacKenzie (djm at rice-chex) * rmdir.c: New file, including -p option for POSIX. Sun Jan 14 21:04:11 1990 David J. MacKenzie (djm at hobbes.ai.mit.edu) * Makefile: Remove rules for making rmdir.o from rm.c. Add rmdir.c to distribution. * rm.c: Remove support for compiling as rmdir. It was messy to begin with, and would have gotten worse when the POSIX -p option was added to rmdir. Remove -D, +debug option and add -v, +verbose option. Change some error messages. Sat Jan 13 00:14:05 1990 David J. MacKenzie (djm at rice-chex) * dirlib.c: New file containing mkdir and rmdir functions for old USG systems (empty for BSD). * Makefile: Ensure that /bin/sh is the shell used. Omit references to defining USG2, as it is no longer used. Break down LIBS into LIBOBJS and LIBS, for versions of make that don't correctly handle dependencies on -lfoo. (dir.o, vdir.o, rmdir.o): Add commented out alternate rules for compilers that can't do -c -o. (install): Use cp -f instead of cp. Instead of copying d and v, link them. (mkdir, cp, rmdir): Depend on dirlib.o. (dist): Add dirlib.c to list of files to distribute. Fri Jan 12 00:58:18 1990 David J. MacKenzie (djm at rice-chex) * chmod.c (describe_change): Remove the word `file' from the messages, since it could be misleading when describing directories and other non-regular files. * mv.c (do_move): Don't use access to determine writability of symlinks, as it will return invalid results. Thu Jan 11 00:51:17 1990 David J. MacKenzie (djm at hobbes.ai.mit.edu) * chmod.c, head.c, ls.c, tail.c (main, usage): Remove version numbers for individual programs, as they have become fairly meaningless. Wed Jan 10 02:34:19 1990 David J. MacKenzie (djm at hobbes.ai.mit.edu) * chmod.c (change_file_mode, nonfatal_perror): Fix enum type clashes. * cat.c: Rename swallow_empty_lines_after_empty_lines to squeeze_empty_lines for old compilers (sheesh!). * cp.c (copy): Change xstat () to (*xstat) () for old compilers. * system.h: Declare getcwd if USG. Use USGr3 and SYSNDIR instead of NDIR macro to determine directory routines header file, for compatibility with glob.c. * Makefile: Revise comments for USG. * mv.c (perror): Declare external errno vars. (do_move): Use lstat rather than stat and access. * ls.c (usage): Split message into two for old compilers. Thu Jan 4 01:02:59 1990 David J. MacKenzie (djm at gnu) * cp.h: Do not declare functions that are declared in <strings?.h>. Wed Jan 3 23:42:26 1990 David J. MacKenzie (djm at hobbes.ai.mit.edu) * system.h: Include <strings.h>, or <string.h> if USG. * cmp.c, du.c, ls.c: Do not directly include <strings.h>. * du.c (blocks_to_kb): If BLKSIZE is defined and equal to 1024, just return the number of blocks. * mv.c (perror): Slight change in "unknown error" message. * Makefile: Mention extra HP/UX flag in comment. Tue Jan 2 01:10:44 1990 David J. MacKenzie (djm at hobbes.ai.mit.edu) * chmod.c (change_dir_mode): Call xmalloc and free less often, and use strcpy instead of sprintf, for speed. * mkdir.c: New program. * Makefile: Add rules for mkdir. * chmod.c: Move several functions into modechange.c and declarations into modechange.h. (change_file_mode): Rename from xchmod. (change_dir_mode): Rename from xchmoddir. * modechange.c: New file of library functions to manipulate file modes. * modechange.h: New header file for modechange.c and programs that use it. * Makefile: Link chmod with modechange.o and include modechange.[ch] in distribution. Sun Dec 31 17:42:55 1989 David J. MacKenzie (djm at rice-chex) * rm.c (rm): Move misplaced quote. Fri Dec 29 03:10:51 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * ln.c (main): Recognize new -f and -i POSIX options, and new -v option for consistency with cp and mv. (do_link): Remove an existing file if -f given, or if -i given and confirmed by user. List files being linked if -v given. (confirm): New function. (usage): Mention new options. * mv.c (do_move): Slight change in query message. (usage): Alphabetize options listing. * rm.c (yesno): Allow 'Y' as well as 'y' to confirm, for consistency with cp and mv. (rm): Flush output before reading. Don't print the program name in the interactive queries, for consistency with cp and mv. * ls.c (get_link_name): Instead of guessing the size of the link name, use the file size from stat. * cp.c (main): exit instead of returning, for the benefit of some C compilers that don't handle a return from main correctly. Recognize new POSIX -f option, `flag_force'. (copy): Use flag_force. Fix typo; had S_IFLINK, wanted S_IFLNK. * cp-aux.c (usage): Mention -f in message and alphabetize the options lists. * rm.c (rm): Make -f option cause -i option to be ignored, for POSIX compatibility. Thu Dec 28 03:25:28 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * Makefile: Change default binary directory from /usr/local/bin to /usr/local/gnubin. * rm.c (xmalloc): Print memory exhausted message even if -f option is given. * cat.c, cp.c, du.c, ln.c, ls.c, mv.c: Declare alloca, with special cases for GNU C and sparc. * du.c, rm.c (xmalloc, xrealloc): Don't pass a null pointer from malloc through if 0 bytes are requested; print an error message, on the assumption that the request for 0 bytes is a bug. Fri Dec 22 23:08:33 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * tail.c (tail_lines): Don't run file_lines on an empty file, to avoid spurious error message. Wed Dec 20 00:33:10 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * du.c (main): Don't truncate a single letter directory name if it is not '/'. * cp.c: Use int instead of uid_t and gid_t; too much trouble to figure out which systems have the typedefs. * system.h: Remove uid_t and gid_t typedefs. Declare alloca if not GNU C or sparc. * mv.c: Move exit (1) from main to usage. (rename): Define if USG, not USG2 (at least this is correct for 386/ix). (perror): New function if USG defined, because System V perror chokes on perror (0). * cat.c, cmp.c, cp-aux.c, dd.c, du.c, head.c, ln.c, ls.c, mv.c, rm.c, tail.c: Combine multiple fprintf calls for usage messages into single calls, to make editing the messages easier. Sat Dec 16 16:06:03 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * Makefile: Add "CC = gcc". * du.c: Change +count-all option to +count-links. Fri Dec 8 21:01:29 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * du.c: Change +combine option to +total. Define INITIAL_PATH_SIZE. Global: fix up some comments and add comments on global variables that lacked them. (usage): Reflect argument change. (main): Use INITIAL_PATH_SIZE. (count_entry): Rename from durec (less cryptic). Use simpler but functionally equivalent code to determine whether to print the entry's size. Mon Dec 4 14:14:22 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * cat.c (cat): Only number blank lines if nonblank lines are also being numbered. Sat Dec 2 13:52:15 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * du.c: Add descriptive comments to global variable definitions. Fri Dec 1 19:10:33 1989 David J. MacKenzie (djm at trix) * cat.c (main): Make numbers_at_empty_lines default to 1 so -n option works. * Makefile: Add -g to default LDFLAGS. (clean): Use /bin/rm so we don't get ./rm, in case it was compiled for a different architecture. Wed Nov 29 10:21:53 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * du.c: Remove #include <sys/param.h> because system.h now does it. Tue Nov 28 00:33:22 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * ls.c (decode_switches): Add new +format, +time, and +sort options that take strings as args to select output style.

MacKenzie (djm at hobbes.ai.mit.edu) * cp-aux.c (user_confirm_overwriting): Print message on stdout instead of stderr to be consistent with mv. Remove accidental second "Usage:" from string. * mv.c (yes): Put getchar value into an int, not a char. * Makefile (dist): Include glob.c in tar file. Sat Nov 25 23:36:54 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * cp-aux.c (usage), cat.c (usage), cmp.c (usage), du.c (usage), head.c (usage), tail.c (usage), ls.c (usage): Combine separate short and long option usage messages into single messages. * mv.c: Add -v (+verbose) function like cp's to list files as they are moved. Indent to make spacing consistent. (main): Handle -v option. (movefile): Remove unneccessary temporary variable. (yes): Flush stdout before reading, as a precaution. (do_move): Stat the source file, then if -v was specified, print the from and to names. Eliminate later stat. (usage): Document -v (+verbose). Fri Nov 24 02:41:27 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * cp-hash.c: Fix spelling in comments. * system.h: For USG, define getwd in terms of getcwd. Try to get MAXPATHLEN from sys/param.h. * du.c: Indent to standardize spacing. Don't declare getwd because system.h now does it. Fix spelling in comments. (xmalloc, xrealloc): New functions to allocate memory with error check. Global: Use xmalloc and xrealloc instead of checking the return value every time. Global: Remove casts to void. (main): Fix apparent typo: had &, wants &&. (durec): Don't simply skip first two directory entries, but check for "." and ".." explicitly. Thu Nov 23 16:41:17 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * rm.c: Rename `no_rmdir_long_opts' to `rm_long_opts'. (main): Merge tests for rmdirflag to determine options into one if statement. Call usage to print usage message. (usage): New function. Mention long options. (xmalloc): Change error message. Return of 0 is ok if 0 bytes requested (ANSI C). * chmod.c (describe_change): Display different messages depending on whether the file's mode has changed or not. (xchmod): Call describe_change with flag telling it whether the file's mode has changed. * cp.c (copy_dir): Instead of always skipping the first two entries of a directory to recursively copy, explicitly skip "." and ".." when they are encountered, because some NFS filesystems have directories without "." and "..". (copy_reg): If less than sizeof(int) bytes have been read, check for blocks of nulls as chars intead of ints; otherwise, the files are zeroed. (But normally use int comparisons for speed.) * cp-aux.c (user_confirm_overwriting): Allow a single RET as a negative response. Flush prompt message in case stderr is line buffered. Use getchar instead of fgetc. * cp-hash.c: Include stdio.h instead of defining NULL. * cp.h: Don't declare fgetc (no longer used). * Makefile: Move BSD macro defs next to USG defs. Add COPYING to tar file, and add release version to tar file and directory names. Change LDLAGS typo to LDFLAGS. Tue Nov 14 09:43:43 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * cat.c (main): Make options more flexible. Add: -E (+show-ends), which is like -e but doesn't imply -v; -T (+show-tabs), which is like -t but doesn't imply -v; -A (+show-all), which is like -ETv. Remove complaints about (needlessly) mutually exclusive options that were there for BSD compatibility, so options accumulate (which is more useful). (usage): Document new option syntax. (cat): Allow tabs to be shown as ^I even if other control and meta characters are not being quoted (so -T works). * Makefile: Add rules for v, vdir, d, and dir. Remove extra rule for cp that defines uid_t and gid_t; now handled in system.h. Remove README-cp from tar files; it was replaced by cp.texinfo. Change CPPFLAGS to LDFLAGS in default rule for making an executable from a .c file. Don't load getopt into dd. Mon Nov 13 10:08:35 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * ls.c (get_link_name): Take code to prepend leading path back out; long output format needs the original link path. (make_link_path): New function to return the full path of a symlink. (gobble_file): Call make_link_path. Use the full path for non-long output formats, the original link path for long format. Sun Nov 12 15:42:43 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * ls.c (gobble_file): Don't exchange the name of a symlink to a directory named on the command line with the name of the directory linked to. (`ls -d /usr/tmp' where /usr/tmp was a symlink to /var/tmp printed `/var/tmp' instead of `/usr/tmp'). (get_link_name): For symlinks that are relative paths, prepend the leading path from the link name. Fri Nov 10 18:13:52 1989 Torbjoern Granlund (tege at echnaton.sics.se) * cp.c: (copy) Don't modify the times for symlinks. The result would be to modify the file which the link points to. (do_copy) Use stat, never lstat, for the target, even if `-d' was specified. Otherwise, it would be forbidden to copy some files to a directory via a symlink pointing to the directory. Sat Nov 11 00:21:32 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * chmod.c (basename): strrchr => rindex. Thu Nov 9 11:46:51 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * rm.c (rm): Make check for symbolic link conditional on S_IFLNK being defined. Wed Nov 8 12:23:33 1989 David J. MacKenzie (djm at spiff) * ls.c: Rename +numerid-id option to +numeric-uid-gid. Thu Nov 9 00:13:03 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * ls.c: Rename +directories-as-files option to +directory. Wed Nov 8 23:14:10 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu) * ls.c: Rename more long options and adjust usage message. Rename all-files to all. Rename almost-all-files to almost-all. Rename question-mark to hide-control-chars. Rename mark-file to classify. Rename file-size to size. Make file-type an alias for classify. Remove long name for -p. Tue Nov 7 21:04:04 1989 David J. MacKenzie (djm at spiff) * ls.c: Make +long a synonym for +verbose and +across an alias for +horizontal. Rename +follow-symbolic-links to +dereference, and +reverse-sort to +reverse. * cmp.c: Rename +byte-info to +verbose and make +quiet an alias for +silent. * du.c: Rename +combined-args to +combine. * head.c, tail.c: Make +silent an alias for +quiet. Sat Nov 4 00:34:00 1989 David J.
