Main features include: (see changes.doc for complete list) - totally rewritten parser, therefore: - local variables, in aliases as well as in batch files - blocks can be formed, redirected, aborted: {e yo;e ho} - $(foo) will insert output of program foo at that point, similar: `foo` - parsing also done with command itself, e.g. '*' is a legal command line - aliases/foreach/forline/fornum/source can be redirected as a whole - direct recursion in aliases prevented, 'alias ls "ls -s"' works - additional speedup; twice as fast as 4.xx, four times as fast as c:Execute - 'assign' now can handle all types of assings correctly under 2.0 - 'class' can pattern-match now, e.g. 'class sound name="mod.*"' - 'copy' has a larger buffer, copy -m' moves files - 'dir -z formatstring' is a very powerful formatting feature, some more opts - 'forline i STDIN' reads args from stdin - 'man' can handle multiple .doc files, so you can document your own aliases - 'source' can handle multiple line blocks of arbitrary length - 'rback'/'run' now set the variable '$_newproc' to the # of the new process - $_abbrev can be used to disable abbreviation if internal commands - $_ioerr contains the secondary return code after an error - $_pipe now holds the directory for the temporary pipe files - $_verbose need to be set to special values, now can trace alias calls - @console tells whether stdin or stdout are interactive - @ioerr converts a secondary error number to a string (like 'Why') - @mounted indicates whether a device has been mounted yet or not - @sortnum sorts its arguments numerically - shift-arrow-up and shift-arrow-down now behave like under AmigaDOS - concatted lines in source files can be arbitrary long - . now stands for current directory, .. for parent Most important bug fixes: - INTERNAL residents can now be used with V37 Kickstarts - c:Execute can be started - 'Wait 5&' as an alias for 'rback Wait 5' now works Miscellaneous info: - Some more documentation, tips & tricks - Executable size: 89K #!/bin/sh # This is a shell archive.

It was, I suppose, originally taken Xfrom a UNIX csh. It does its job in two steps: X XFirst comes the preformatting, which is done while copying the original Xline to a temporary buffer. It is important to make a difference between Xquoted and and unquoted characters. Earlier shell versions of the shell Xset the most significant bit of quoted chars, but this made the use of Xinternational character sets impossible. Now it's done the other way Xround: Every _unquoted_ char with special meaning (e.g. the asterisk) is Xreplaced by a number between 128 and 159. Ascii code 160 is used as word Xseparator in strings (so words may contain blanks). X XAfter the preformatting is done, the parser's main task is building up the Xargument array av[i] for the internal and external commands. Memory is Xallocated for every argument and the argument is put together from one or Xmore tokens (e.g. $a$b). After av[0] has been completed, certain flags Xare set in order to do things like preventing wild card expinsion of Xarguments to 'dir'. X XThen, with the argument line is complete, the aliases list is searched for Xa name that matches av[0]. If it exists, the parser is called recursively Xwith the alias's command line. Recursive calls of the parser (using the Xfunction execute()) have no more side effects at all since version 5.1 and Xcan therefore used to do things like automatic cd and class features. X XIn order to speed up this process with many allocations and deallocations, XI have written a custom storage allocator. It allocates groups of X1000-byte-blocks (called frames) using malloc() and then distibutes them Xuntil they're used up. Of course, deallocation of single allocations is Xnot possible, only the frame as a whole can be deallocated. But that's Xokay, since all temporaries are deallocated when the parser is left. X X XTHE BUILTINS X------------ X XThe other side of the shell are the built in commands. They look much like XCLI commands in C, but they have lots of support functions for their needs. X XTo write a builtin command for CShell, you use the global variables av and Xac instead of argv and argc, and use printf() for output. That's it. Any Xother changes, if necessary, will be done by me. X XEvery builtin command has its equivalent as a C function with the prefix Xdo_ (example: do_addbuffers). The are no hard coded jumps to any of those Xfunctions, instead there is a table with the descriptions of all functions X(like name, usage, minimum arguments and, last but not least, a pointer to Xthat function). X X XWHY BUILT IN COMMANDS? X---------------------- X XThe reasons why C-Shell still relies heavily on internal commands: X- They can take advantage from each other (e.g. class recognition in the X 'dir' command, use of 'search' command in quick cd) X- They have a fast calling sequence X- They need no hard disk seeks, so the startup can be accelerated X significantly X- They are shorter than external commands X- And finally, if you don't like them, don't use them. The wasted resources X become more and more negligible nowadays... CShell uses 2% of my memory. X X XSOURCES X------- X XThe source for CShell is available, if you don't have it, request it from Xme. It consists of 10 modules, together 200K. It is compilable under SAS X(Lattice) & Manx C, although the executables produced by Manx are not Xresidentable. If you want to modify it, ask me for an up-to-date version Xfirst. You may not release modified versions (imagine the chaos if Xeverbody releases his private csh), but if you send them to me, you have a Xgood chance that I'll build it in. You'll be, of course, be mentioned in Xthe docs. X XEven if you don't intend to modify it, I still encourage you to get the Xsource, because there are so many things you can look up there once you Xneed them (did *you* know how to set the system date?). I apologize for my Xpoor to nonexistent comments, I'll go through again when I've got the time. XAh, yes, that famous Dillon-formatting is gone, now it's traditionally Xformatted.

XAssume, for example, you just typed X$ rm dh1:graphics/lo-res/gorilla Xwhen it comes to your mind that would prefer to keep a copy of that pic on Xdiskette. Many would now delete this command line. Being a smart guy, you Xdo the following: X$ [CTRL-N] (leaves this command line alone) X$ co[CTRL-T] df0: X$ [Up-Arrow][Up-Arrow] (gets back the command line you left) X X XIn case you don't know what history completion is: X$ search *.c *.h makefile foobar X$ ram: X$ dir X$ rm tmpfile XNow if want to repeat the search command, enter X$ se[Shift-Up-Arrow] Xwhich brings up the the last command that started with 'se'. X X XIf you want to delete the file X$ dh2:comm/uucp/mail/junk/409 Xand you're far away from that directory, enter X$ ju[ESC-c]409 (enters the result of cd ju) X X XThe same function is also usable for 'cd'. Assume you have several 'junk' Xdirectories: X$ ju[ESC-c][CTRL-R][CTRL-R][CTRL-R] XLike this you'll cycke through the junk directories. When you've got the Xright one, press enter. X X XAssume there are the files comm1.c, comm2.c, and comm3.c as well as their Xcorresponding .o files. You want comm3.c: X$ co[Shift-Tab]1[Tab] XOf course this is more useful with longer file names. X X XYou can tab file name expand any patterns, not only abbreviations. Assume Xyou want to delete all .c files in the current directory but the last: X$ rm *.c[ESC-Tab][CTRL-W] XIn addition, you get to see all the files once again before deleting them. X X XNext one: You have entered: X$ dir X$ foreach i ( *.c ) "e >>ram:temp $i X$ more ram:temp Xand you would like to execute the same three statements again, enter: X$ [Up-Arrow][Up-Arrow][Up-Arrow][ESC-Return][CTRL-R][CTRL-R] X X XI know that the editing is not very user friendly. This is because it's Xquite hard and troublesome to get raw keycodes from the console, and it's Ximpossible to get them from a VT200 terminal. Therefore I had to stick Xwith CTRL and ESC combinations. Once you have learnt them (some of them are Xsimilar to EMACS), you can save lots of typing. X X X COMMANDS X X XMy advice here is clear: Use aliases, aliases, aliases. In order to be Xable to create them as quickly as possible, create an alias (e.g. 'le') Xthat edits your login file, plus another one (e.g. 'lx'), that re-executes Xit. My login contains almost only aliases, everthing else I've put in X'firstlogin.sh'. X X XIf you don't like the default options of one command, you can add more of Xthem using an alias: X$ alias dir "dir -q XFrom now on, blocks will no longer be displayed in 'dir'. X X XIf your aliases have arguments, e.g. X$ alias sc "search *.c Xproblems arise when you try to specify options. e.g. case sensitivity: X$ sc -c "hello world Xthis will obviously not work. That's what @pickopts is good for: X$ alias sc "%a search @pickopts( $a ) *.c @pickargs( $a ) X X XOnce you have more aliases, it is useful to keep them sorted. You might Xalso document them: Create a file 'aliases.doc', and perform X$ set _man aliases.doc csh.doc XThat way, you can document them in a separate file.
