X XIf you don't have the Toolkit, you can construct a helpfile by Xgleaning short command descriptions from your manual, and adding Xthem to "/usr/lib/helpfile", according the the pattern of the partial Xhelpfile shown below. X XI find this help command more useful than the help system distributed with XSystem V, especially on machines with limited disk space, where it is not Xpractical to keep the manuals on-line. X XThe program uses an indexfile, /usr/lib/helpindex, to speed up access; Xif the indexfile does not exist, or is older than /usr/lib/helpfile (indicating Xthat the helpfile has been updated), the program will build a new indexfile. X XCompile normally, (small model on Uport V/286), then invoke as "help". The Xprogram should be owned by root and suid, so it can write in /usr/lib (to Xrecreate the index file as needed.). X XThe helpfile below consists of those help entries which I have added to Xthe MKS Toolkit file to use with my UNIX system. I do not feel free to Xpost the MKS helpfile, since it is no doubt (c) by MKS. X XPut the helpfile into /usr/lib/helpfile, or change the references thereto in Xhelp.c. X XI hope this is helpful. Civil and constructive comments are invited to Xihnp4!killer!dcs!wnp, flames should be directed to /dev/null. X XWolf N. Paul Xihnp4!killer!dcs!wnp X X XP.S. Since first posting this to comp.unix.microport, another application Xhas been suggested for this command - an online, free-form notebook. X XActually, any kind of information can be kept in a "helpfile" for this Xcommand, as long as each item of info starts with a line containing X'#' and a number of keywords separated by commas (currently each keyword Xmust be less than 14 characters long and cannot contain white space). XJohn Plocher's addition of looking at $HELPDIR and $HELPFILE permits one Xto put info into a file $HOME/.notebook, and to access it using the enclosed X"info" shellscript. X XAgain, i hope this i helpful.

X * It is particularly useful on systems with restricted X * diskspace, where it is not practical to keep the manuals X * on-line. X * The command is patterned after the MKS Toolkit command X * of the same name. If no /usr/lib/helpindex file exists, or if X * it is older than the helpfile, a new helpindex will be X * created to allow faster access to the helpscreens by X * means of fseek(). X * Desirable enhancements would include the possibility to X * have help look in an environment variable HELPFILE for X * an alternate or additional helpfile, X * [ Done by John Plocher - uses HELPDIR to set the directory X * where the help file and its index are. It also uses HELPFILE X * to give the name of the data file ($HELPFILE.idx is the index) X * defaults are "/usr/lib" and "helpfile" ] X * and/or to have help look in $HOME/.helpfile if a command X * is not found in the default helpfile. X * Another useful feature would be the possibility of using X * a pager specified by $PAGER to output the help info, since X * a few entries (stty, vi, ...) are longer than one screen. X * No doubt the coding could be considerably improved, and X * any suggestions would be more than welcome.

It also attaches a header and Xchecksum information used by the reverse filter atob to find the start of the Xdata and to check integrity. X XAtob reads an encoded file, strips off any leading and trailing lines added Xby mailers, and recreates a copy of the original file on the standard Xoutput. Atob gives NO output (and exits with an error message) if its input Xis garbage or the checksums do not check. X# chmod Xchmod -- change file modes XUsage: chmod mode file ... X XMode can be either SYMBOLIC or OCTAL. X XSYMBOLIC MODES: X [who] op perm X Xwho: `u' (user), `g' (group), `o' (others); `a' is equivalent to `ugo'; X Xop: + adds permission, - removes permission, = sets absolute permissions X Xperm: `r' read, `w' write, `x' execute (or search for directories); X Super-User only: X `s' set UID or set GID; `t' save text/sticky bit.

X XOnly the owner of a file (or the Superuser) can change the owner or group Xof that file. X# col Xcol -- convert reverse and half line feeds from nroff XUsage: col [-f -b -x -p] [file(s)] X-f output device can perform forward half line feeds X-b output device is cannot backspace X-x do not output tabs for multiple spaces X-p let unrecognized escape sequences (other than ESC 7, ESC 8, and X ESC 9) pass. XCol is used to print nroff output on devices that cannot perform forward and Xreverse half line motions or reverse line feeds, as is the case with most Xsimple printers and CRT terminals.

X-t Print title on the banner page of the output X-w Write a message on the user's terminal when files have been printed. XCancel cancels line printer requests that were made with the lp command. XThe commandline arguments may be either request ids as returned by lp without Xthe -s option, or printer names (for a complete list do "lpstat"). X# lpstat Xlpstat -- print LP status information XUsage: lpstat [options] X-a list Print acceptance status (with respect to lp) of destinations for X requests. "List" is a list of intermixed printer and class names. X-c list Print class names and their members. "List" is a list of class names. X-d Print the default destination for lp. X-o list Print the status of output requests. "List" is a list of intermixed X printer names, class names, and request ids. X-p list Print the status of printers. "List" is a list of printer names. X-r Print the status of the LP request scheduler. X-s Print a status summary X-t Print all status information X-u list Print status of output requests for users. "List" is a list of login X names. X-v list Print the names of printers and the pathnames of devices associated X with them. "List" is a list of printer names. XIf "list" is omitted in the above options, all information relevant to the Xoption letter will be printed. X# mail, mailx Xmail, mailx -- electronic mail programs XUsage: mail # to check for mail X mailx X mail user # to send mail to user X mailx user XThe options and commands for these two programs are too numerous Xto list here. See the manual entries and tutorials if you need more information Xthan shown above.

XWith argument `-', newgrp sets up the environment as if the user had Xactually logged in again as a member of the specified group. XWithout arguments, the group id is set back to that specified in /etc/passwd. X# nice Xnice -- run a command at a low priority XUsage: nice [-increment] command [arguments] XNice executes command with a lower CPU scheduling priority. If no "increment" Xargument is given, a default of 10 is used. XOnly the Superuser may run commands with higher-than-usual priority by using Xa negative increment (e.g. --10). X# nohup Xnohup - run a command immune to hangups and quits XUsage: nohup command [arguments] XIf nohup should apply to several commands, they should be placed in a file Xand invoked as "nohup sh commandfile". XIf the output from "command" is not redirected by the user, it will be placed Xinto a file nohup.out in the current or HOME directory of the user. X# nroff Xnroff -- text formatter for line printer devices XUsage: nroff [options] [files] X-olist print only pages listed; ranges are allowed X-nN number first page N X-sN stop every N pages to allow paper loading or X changing.

X-kname Compact the macros used in this invocation of otroff, placing the output X in files [dt].name in the current directory. X-t Direct output to the standard output instead of the phototypesetter. X-f Refrain from feeding out paper and stopping the phototypesetter at the X end of the run. X-w Wait until phototypesetter is ready, if it is currently busy. X-b Report on busy/ready status of phototypesetter. No text processing X is done. X-a Send a printable ASCII approximation of the result to the standard X output. X-pN print all characters in point size N while retaining all prescribed X spacings and motions, to reduce phototypesetter elapsed time. X-Tcat Use font-width tables for Wang C/A/T phototypesetter. This is both X the default and the only choice. X# ps Xps -- display process status XUsage: ps [options] X-e Print information about all processes X-d Print information about all processes, except process group leaders X-a Print information about all processes, except process group leaders X and processes not associated with a terminal X-f Generate a full listing X-l Generate a long listing X-cfile Use the specified core file instead of /dev/mem X-sdev Use the specified swap device instead of /dev/swap X-nfile Use specified file instead of /unix X-tlist Restrict listing to processes associated with terminals given in list.

Xline i set line discipline to i ( 0 < i < 127 ). X XCOMBINATION MODES Xevenp or parity parenb cs7 Xoddp parenb cs8 parodd X-parity -parenb cs8 X-evenp -parenb cs8 X-oddp -parenb cs8 Xraw (-raw or cooked) enable (disable) raw input and output (no ERASE, KILL, X INTR, QUIT, SWTCH, EOT, or output post processing).

XLCASE (-LCASE) same as lcase (-lcase) Xtabs (-tabs or tab3) preserve (expand to spaces) tabs when printing Xek set ERASE and KILL characters back to # and @. Xsane reset all modes to some reasonable values Xterm set all modes suitable for the terminal type term, X where term is one of tty33, tty37, vt05, tn300, ti700, X or tek. X XIF THIS FLASHED BY QUICKER THAN YOU COULD READ IT, TRY IT AGAIN LIKE THIS: X X help stty | more X X# su Xsu -- become super-user or another user XUsage: su [-] [name [arg ...]] X- If the first argument to su is `-', the environment will be changed X to what it would be if the user actually logged in as "name". Xname If name is given, become that user. If no name is given, become X root (e.g. the super-user). Xarg Optional arguments are passed to the shell invoked by su. X Thus, "su - bin -c command args" executes "command" with the temporary X environment and permissions of user "bin". X# tput Xtput - query terminfo database XUsage: tput [-Ttype] capname [parms...] X-Ttype indicates the type of terminal. Normally unnecessary, since X the default is taken from the environment variable TERM. Xcapname indicates the attribute (capabilitry) from the terminfo database Xparms if the capability needs parameters, the argument parms will be X instantiated into the string. X# troff Xtroff, ditroff -- text formatter for typesetters and other high-resolution X output devices XUsage: troff [options] [files] X-o list Print only pages whose numbers appear in "list". X-nN Number first page generated N. X-sN Generate output to encourage typesetter to stop every N pages X-mname Prepend the macro file /usr/lib/tmac/tmac.name to the input files. X-raN Set register a (one-character name) to N. X-i Read standard input after the input files are exhausted. X-q Invoke the simultaneous input-output mode of the .rd request X-z Print only messages generated by the .tm request X-a Send a printable ASCII approximation of the results to the standard X output. X-Tdest Prepare output for typesetter dest. X# true Xtrue, : , false -- provide truth values XUsage: : [argument ...] X true [argument ...] X false XTrue and : do nothing, successfully. False does nothing, unsuccessfully. X: is also used as a magic number for Bourne or Korn shell scripts in a XC-Shell environment. X# tty Xtty -- get name of terminal XUsage: tty [-l] [-s] X-l print synchronous line number if the terminal is on an active X synchronous line X-s prevent printing of tty pathname, return result as a return code. X 2 - invalid options; 0 - if tty is a terminal; 1 - otherwise X# umask Xumask -- set file-creation mode mask XUsage: umask [ooo] XWithout an argument, umask prints the current value of the mask. XWith argument, umask sets the mask to the value specified by the three-digit Xoctal number. See help entry for chmod for legal values. X# write Xwrite -- write to another user XUsage: write user [line] XIf you want to write to a user who is logged in more than once, the X"line" argument may be used to direct which terminal to write to. XPermission to write may be denied or granted by the use of mesg(1). XDuring a write session, a line starting with ! will cause the rest Xof that line to be passed to the shell as a command. XTerminate a write session with your INTR or EOF character.
