.TH CRONTAB 1 "29 December 1993"
|
|
.UC 4
|
|
.SH NAME
|
|
crontab \- maintain crontab files for individual users (V3)
|
|
.SH SYNOPSIS
|
|
crontab [ -u user ] file
|
|
.br
|
|
crontab [ -u user ] { -l | -r | -e }
|
|
.SH DESCRIPTION
|
|
.I Crontab
|
|
is the program used to install, deinstall or list the tables
|
|
used to drive the
|
|
.IR cron (8)
|
|
daemon in Vixie Cron. 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 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.
