NAME
crontab - user crontab file
SYNOPSIS
crontab [file]
crontab -r
crontab -l
DESCRIPTION
crontab copies the specified file, or standard input if no file is
specified, into a directory that holds all users' crontab files (see
cron(1M)). The -r option removes a user's crontab from the crontab
directory. crontab -l lists the crontab file for the invoking user.
Users are permitted to use crontab if their names appear in the file
/usr/lib/cron/cron.allow. If that file does not exist, the file
/usr/lib/cron/cron.deny is checked to determine if the user should be
denied access to crontab. If neither file exists, only root is
allowed to submit a job. If only cron.deny exists and is empty,
global usage is permitted. The allow/deny files consist of one user
name per line.
A crontab file consists of lines of six fields each. The fields are
separated by spaces or tabs. The first five are integer patterns that
specify the following:
minute (0-59),
hour (0-23),
day of the month (1-31),
month of the year (1-12),
day of the week (0-6 with 0=Sunday).
Each of these patterns can be either an asterisk (meaning all legal
values), or a list of elements separated by commas. An element is
either a number, or two numbers separated by a hyphen (meaning an
inclusive range). Note that the specification of days can be made by
two fields (day of the month and day of the week). If both are
specified as a list of elements, both are adhered to. For example, 0
0 1,15 * 1 runs a command on the first and fifteenth of each month, as
well as on every Monday. To specify days by only one field, the other
field should be set to * (for example, 0 0 * * 1 runs a command only
on Mondays).
The sixth field of a line in a crontab file is a string that is
executed by the shell at the specified times. A percent character in
this field (unless escaped by \) is translated to a new-line
character. Only the first line (up to a % or end of line) of the
command field is executed by the shell. The other lines are made
available to the command as standard input.

The shell is invoked from your $HOME directory with an initial
argument of sh. Users who desire to have their .profile executed must
explicitly do so in the crontab file. cron supplies a default
environment for every shell, defining HOME, LOGNAME, SHELL=/bin/sh,
and PATH=:/bin:/usr/bin.
EXTERNAL INFLUENCES
International Code Set Support
Single-byte character code sets are supported.
WARNINGS
Be sure to redirect the standard output and standard error from
commands. If this is not done, any generated output or errors are
mailed to the user.
