-.Sh DESCRIPTION
-.Nm
-and
-.Nm batch
-read commands from standard input or a specified file which
-are to be executed at a later time, using
-.Xr sh 1 .
-.Bl -tag -width indent
-.It Nm at
-Executes commands at a specified time.
-.It Nm atq
-Lists the user's pending jobs, unless the user is the superuser.
-In that case, everybody's jobs are listed.
-.It Nm atrm
-Deletes jobs.
-.It Nm batch
-Executes commands when system load levels permit.
-In other words, when
-the load average drops below 1.5, or the value specified in the invocation of
-.Xr atrun 8 .
-.El
-.Pp
-.Nm
-allows some moderately complex
-.Ar time
-specifications.
-It accepts times of the form
-.Ar HHMM
-or
-.Ar HH:MM
-to run a job at a specific time of day.
-(If that time is already past, the next day is assumed.)
-You may also specify
-.Sq midnight ,
-.Sq noon ,
-or
-.Sq teatime
-(4pm)
-and you can have a time-of-day suffixed with
-.Sq AM
-or
-.Sq PM
-for running in the morning or the evening.
-You can also say what day the job will be run,
-by giving a date in the form
-.Ar %month-name day
-with an optional
-.Ar year ,
-or giving a date of the form
-.Ar MMDDYY
-or
-.Ar MM/DD/YY
-or
-.Ar DD.MM.YY .
-The specification of a date must follow the specification of
-the time of day.
-You can also give times like
-.Op Nm now
-or
-.Op Nm now
-.Sq + Ar count %time-units ,
-where the time-units can be
-.Sq minutes ,
-.Sq hours ,
-.Sq days ,
-.Sq weeks ,
-.Sq months ,
-or
-.Sq years
-and you can tell
-.Nm
-to run the job today by suffixing the time with
-.Sq today
-and to run the job tomorrow by suffixing the time with
-.Sq tomorrow .
-.Pp
-For example, to run a job at 4pm three days from now, you would do
-.Dl at 4pm + 3 days ,
-to run a job at 10:00am on July 31, you would do
-.Dl at 10am Jul 31
-and to run a job at 1am tomorrow, you would do
-.Dl at 1am tomorrow .
-.Pp
-Alternatively the time may be specified in a language-neutral fashion
-by using the
-.Fl t
-options.
-.Pp
-For both
-.Nm
-and
-.Nm batch ,
-commands are read from standard input or the file specified
-with the
-.Fl f
-option and executed.
-The working directory, the environment (except for the variables
-.Ev TERM ,
-.Ev TERMCAP ,
-.Ev DISPLAY
-and
-.Ev _ )
-and the
-.Ar umask
-are retained from the time of invocation.
-An
-.Nm
-or
-.Nm batch
-command invoked from a
-.Xr su 1
-shell will retain the current userid.
-The user will be mailed standard error and standard output from his
-commands, if any.
-Mail will be sent using the command
-.Xr sendmail 1 .
-If
-.Nm
-is executed from a
-.Xr su 1
-shell, the owner of the login shell will receive the mail.
-.Pp
-The superuser may use these commands in any case.
-For other users, permission to use
-.Nm at
-is determined by the files
-.Pa /var/at/at.allow
-and
-.Pa /var/at/at.deny .
-.Pp
-If the file
-.Pa /var/at/at.allow
-exists, only usernames mentioned in it are allowed to use
-.Nm .
-.Pp
-If
-.Pa /var/at/at.allow
-does not exist,
-.Pa /var/at/at.deny
-is checked; every username not mentioned in it is then allowed
-to use
-.Nm .
-.Pp
-If neither exists, only the superuser is allowed use of
-.Nm .
-.Pp
-An empty
-.Pa /var/at/at.deny
-means that every user is allowed use these commands.
-This is the default configuration.
-.Sh OPTIONS
-.Bl -tag -offset indent -width XqXqueueXX
-.It Fl b
-Is an alias for
-.Nm batch .
-.It Fl c
-Cats the jobs listed on the command line to standard output.
-.It Fl d
-Is an alias for
-.Nm atrm .
-.It Fl f Ar file
-Reads the job from
-.Ar file
-rather than standard input.
-.It Fl l
-Is an alias for
-.Nm atq .
-.It Fl m
-Send mail to the user when the job has completed even if there was no
-output.
-.It Fl q Ar queue
-Uses the specified queue.
-A queue designation consists of a single letter.
-Valid queue designations
-range from
-.Sq a
-to
-.Sq z
-and
-.Sq A
-to
-.Sq Z .
-The
-.Sq c
-queue is the default for
-.Nm
-and the
-.Sq E
-queue for
-.Nm batch .
-Queues with higher letters run with increased niceness.
-If a job is submitted to a queue designated with an uppercase letter, it
-is treated as if it had been submitted to batch at that time.
-If
-.Nm atq
-is given a specific queue, it will only show jobs pending in that queue.
-.It Fl r
-Is an alias for
-.Nm atrm .
-.It Fl t
-For both
-.Nm
-and
-.Nm batch ,
-the time may be specified in a language-neutral format consisting of:
-.Bl -tag -width Ds -compact -offset indent
-.It Ar CC
-The first two digits of the year (the century).
-.It Ar YY
-The second two digits of the year.
-If
-.Ar YY
-is specified, but
-.Ar CC
-is not, a value for
-.Ar YY
-between 69 and 99 results in a
-.Ar CC
-value of 19.
-Otherwise, a
-.Ar CC
-value of 20 is used.
-.It Ar MM
-The month of the year, from 01 to 12.
-.It Ar \&DD
-The day of the month, from 01 to 31.
-.It Ar hh
-The hour of the day, from 00 to 23.
-.It Ar mm
-The minute of the hour, from 00 to 59.
-.It Ar \&SS
-The second of the minute, from 00 to 61.
-.El
-.It Fl V
-Prints the version number to standard error.
-.It Fl v
-For
-.Nm atq ,
-shows completed but not yet deleted jobs in the queue.
-Otherwise shows the time the job will be executed.
-.El
-.Sh FILES
-.Bl -tag -width /var/at/.lockfile -compact
-.It Pa /var/at/jobs
-Directory containing job files
-.It Pa /var/at/spool
-Directory containing output spool files
-.It Pa /var/run/utmp
-Login records
-.It Pa /var/at/at.allow
-Allow permission control
-.It Pa /var/at/at.deny
-Deny permission control
-.It Pa /var/at/.lockfile
-Job-creation lock file.

-.Sh STANDARDS
-The
-.Nm
-and
-.Nm batch
-utilities conform to
-.St -p1003.2-92 .
-.Sh AUTHORS
-.An -nosplit
-.Nm
-was mostly written by
-.An Thomas Koenig Aq Mt ig25@rz.uni-karlsruhe.de .
-The time parsing routines are implemented by
-.An David Parsons Aq Mt orc@pell.chi.il.us .
-.Sh BUGS
-If the file
-.Pa /var/run/utmp
-is not available or corrupted, or if the user is not logged on at the
-time
-.Nm
-is invoked, the mail is sent to the userid found
-in the environment variable
-.Ev LOGNAME .
-If that is undefined or empty, the current userid is assumed.
-.Pp
-.Nm
-and
-.Nm batch
-as presently implemented are not suitable when users are competing for
-resources.
-If this is the case for your site, you might want to consider another
-batch system, such as
-.Ic nqs .
