Paul Vixie's cron, version 3.0. Munged into bmake format. If this goes
well, expect our two seperate directories for cron and crontab to go away
shortly.

Each user can have their own crontab, and though +these are files in /var, they are not intended to be edited directly. +.PP +If the +.I allow +file exists, then you must be listed therein in order to be allowed to use +this command. If the +.I allow +file does not exist but the +.I deny +file does exist, then you must \fBnot\fR be listed in the +.I deny +file in order to use this command. If neither of these files exists, then +depending on site-dependent configuration parameters, only the super user +will be allowed to use this command, or all users will be able to use this +command. +.PP +If the +.I -u +option is given, it specifies the name of the user whose crontab is to be +tweaked. If this option is not given, +.I crontab +examines "your" crontab, i.e., the crontab of the person executing the +command. Note that +.IR su (8) +can confuse +.I crontab +and that if you are running inside of +.IR su (8) +you should always use the +.I -u +option for safety's sake. +.PP +The first form of this command is used to install a new crontab from some +named file or standard input if the pseudo-filename ``-'' is given. +.PP +The +.I -l +option causes the current crontab to be displayed on standard output. +.PP +The +.I -r +option causes the current crontab to be removed. +.PP +The +.I -e +option is used to edit the current crontab using the editor specified by +the \s-1VISUAL\s+1 or \s-1EDITOR\s+1 environment variables. After you exit +from the editor, the modified crontab will be installed automatically. +.SH "SEE ALSO" +crontab(5), cron(8) +.SH FILES +.nf +/var/cron/allow +/var/cron/deny +.fi +.SH STANDARDS +The +.I crontab +command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax +differs from previous versions of Vixie Cron, as well as from the classic +SVR3 syntax. +.SH DIAGNOSTICS +A fairly informative usage message appears if you run it with a bad command +line. +.SH AUTHOR +.nf +Paul Vixie <paul@vix.com> |
