+.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.
+.SH "SEE ALSO"
+crontab(5), crond(8)
+.SH FILES

+/var/cron/deny

+.SH DIAGNOSTICS
+A fairly informative usage message appears if you run it with a bad command
+line.

+.TH CRONTAB 5 "15 January 1990"
+.UC 4
+.SH NAME
+crontab \- tables for driving cron
+.SH DESCRIPTION
+A
+.I crontab
+file contains instructions to the
+.IR crond (8)
+daemon of the general form: ``run this command at this time on this date''.
+Each user has their own crontab, and commands in any given crontab will be
+executed as the user who owns the crontab. Uucp and News will usually have
+their own crontabs, eliminating the need for explicitly running
+.IR su (1)
+as part of a cron command.
+.PP
+Blank lines and leading spaces and tabs are ignored. Lines whose first
+non-space character is a pound-sign (#) are comments, and are ignored.
+Note that comments are not allowed on the same line as cron commands, since
+they will be taken to be part of the command. Similarly, comments are not
+allowed on the same line as environment variable settings.
+.PP
+An active line in a crontab will be either an environment setting or a cron
+command. An environment setting is of the form,
+.PP
+ name = value
+.PP
+where the spaces around the equal-sign (=) are optional, and any subsequent
+non-leading spaces in
+.I value
+will be part of the value assigned to
+.IR name .
+The
+.I value
+string may be placed in quotes (single or double, but matching) to preserve
+leading or trailing blanks.
+.PP
+Several environment variables are set up
+automatically by the
+.IR crond (8)
+daemon from the /etc/passwd line of the crontab's owner: USER, HOME, and SHELL.
+HOME and SHELL may be overridden by settings in the crontab; USER may not.
+.PP
+(Note: for UUCP, always set SHELL=/bin/sh, or
+.IR crond (8)
+will cheerfully try to execute your commands using /usr/lib/uucp/uucico.)
+.PP
+(Another note: the USER variable is sometimes called LOGNAME or worse on
+System V... on these systems, LOGNAME will be set rather than USER.)
+.PP
+In addition to USER, HOME, and SHELL,
+.IR crond (8)
+will look at MAILTO if it has any reason to send mail as a result of running
+commands in ``this'' crontab. If MAILTO is defined (and non-empty), mail is
+sent to the user so named. If MAILTO is defined but empty (MAILTO=""), no
+mail will be sent. Otherwise mail is sent to the owner of the crontab. This
+option is useful if you decide on /bin/mail instead of /usr/lib/sendmail as
+your mailer when you install cron -- /bin/mail doesn't do aliasing, and UUCP
+usually doesn't read its mail.
+.PP
+The format of a cron command is very much the V7 standard, with a number of
+upward-compatible extensions. Each line has five time and date fields,
+followed by a command. Commands are executed by
+.IR crond (8)
+when the minute, hour, and month of year fields match the current time,
+.I and
+when at least one of the two day fields (day of month, or day of week)
+match the current time (see ``Note'' below).
+.IR crond (8)
+examines cron entries once every minute.
+The time and date fields are:
+.IP
+.ta 1.5i
+field allowed values
+.br
+----- --------------
+.br
+minute 0-59
+.br
+hour 0-23
+.br
+day of month 0-31
+.br
+month 0-12 (or names, see below)
+.br
+day of week 0-7 (0 or 7 is Sun, or use names)
+.br
+.PP
+A field may be an asterisk (*), which always matches the
+current time.
+.PP
+Ranges of numbers are allowed. Ranges are two numbers separated
+with a hyphen. The specified range is inclusive. For example,
+8-11 for an ``hours'' entry specifies execution at hours 8, 9, 10
+and 11.
+.PP
+Lists are allowed. A list is a set of numbers (or ranges)
+separated by commas. Examples: ``1,2,5,9'', ``0-4,8-12''.
+.PP
+Step values can be used in conjunction with ranges. Following
+a range with ``/<number>'' specifies skips of the number's value
+through the range. For example, ``0-23/2'' can be used in the hours
+field to specify command execution every other hour (the alternative
+in the V7 standard is ``0,2,4,6,8,10,12,14,16,18,20,22'').
+.PP
+Names can also be used for the ``month'' and ``day of week''
+fields. Use the first three letters of the particular
+day or month (case doesn't matter). Ranges or
+lists of names are not allowed.
+.PP
+The ``sixth'' field (the rest of the line) specifies the command to be
+run.
+The entire command portion of the line, up to a newline or %
+character, will be executed by the user's login shell or by the shell
+specified in the SHELL variable of the cronfile.
+Percent-signs (%) in the command, unless escaped with backslash
+(\\), will be changed into newline characters, and all data
+after the first % will be sent to the command as standard
+input.
+.PP
+Note: The day of a command's execution can be specified by two
+fields \(em day of month, and day of week. If both fields are
+restricted (ie, aren't *), the command will be run when
+.I either
+field matches the current time. For example,
+.br
+``30 4 1,15 * 5''
+would cause a command to be run at 4:30 am on the 1st and 15th of each
+month, plus every Friday.
+.SH EXAMPLE CRON FILE
+.nf
+
+# use /bin/sh to run commands, no matter what /etc/passwd says
+SHELL=/bin/sh
+# mail any output to `paul', no matter whose crontab this is
+MAILTO=paul
+#
+# run five minutes after midnight, every day
+5 0 * * * $HOME/bin/daily.job >> $HOME/tmp/out 2>&1
+# run at 2:15pm on the first of every month -- output mailed to paul
+15 14 1 * * $HOME/bin/monthly
+# run at 10 pm on weekdays, annoy Joe
+0 22 * * 1-5 mail -s "It's 10pm" joe%Joe,%%Where are your kids?%
+23 0-23/2 * * * echo "run 23 minutes after midn, 2am, 4am ..., everyday"
+5 4 * * sun echo "run at 5 after 4 every sunday"
+.fi
+.SH SEE ALSO
+crond(8), crontab(1)
+.SH EXTENSIONS
+When specifying day of week, both day 0 and day 7 will be considered Sunday.
+BSD and ATT seem to disagree about this.
+.PP
+Lists and ranges are allowed to co-exist in the same field. "1-3,7-9" would
+be rejected by ATT or BSD cron -- they want to see "1-3" or "7,8,9" ONLY.
+.PP
+Ranges can include "steps", so "1-9/2" is the same as "1,3,5,7,9".
+.PP
+Names of months or days of the week can be specified by name.
+.PP
+Environment variables can be set in the crontab. In BSD or ATT, the
+environment handed to child processes is basically the one from /etc/rc.
+.PP
+Command output is mailed to the crontab owner (BSD can't do this), can be
+mailed to a person other than the crontab owner (SysV can't do this), or the
+feature can be turned off and no mail will be sent at all (SysV can't do this
+either).
