.TH CRONTAB 1 "9 December 1988"
|
|
.UC 4
|
|
.SH NAME
|
|
crontab \- maintain crontab files for individual users
|
|
.SH SYNOPSIS
|
|
crontab [ -u user ] { -l | -d | -r file }
|
|
.SH DESCRIPTION
|
|
.I Crontab
|
|
is the program used to install, deinstall or list the tables
|
|
used to drive the
|
|
.IR crond (8)
|
|
daemon in Vixie Cron. Each user has their own crontab, and though these are
|
|
files in /var, they are not readable or writable by anyone or anything
|
|
except the super-user or the
|
|
.IR crond (8)
|
|
or
|
|
.I crontab
|
|
programs.
|
|
.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
|
|
.I -l
|
|
option causes the current crontab to be displayed on standard output.
|
|
.PP
|
|
The
|
|
.I -d
|
|
option causes the current crontab to be deleted.
|
|
.PP
|
|
The
|
|
.I -r
|
|
option is used to replace the current
|
|
crontab (if any) with the contents of the named file.
|
|

|
|
line.
