      proto - prototype job file for at(1)


      /var/adm/cron/.proto. queue

      When a job is submitted to at or batch, the job is constructed as a
      Bourne shell script (see at(1)).	The job file is created in
      /var/spool/cron/atjobs as follows:

	   +  at creates a header describing the job as an at job or a batch
	      job.  at jobs submitted to all queues other than queue a are
	      listed as batch jobs.  The header is:

		   : at job	     for an at job, or

		   : batch job	     for a batch job.

	   +  A set of Bourne shell commands is added to make the
	      environment (see environ(5)) for the at job the same as the
	      current environment.

	   +  at then copies text from the prototype file to the job file,
	      except for special variables that are replaced by other text:

		   $d	 Replaced by the current working directory.

		   $l	 Replaced by the current file size limit (see

		   $m	 Replaced by the current umask (see umask(2)).

		   $t	 Replaced by the time at which the job should be
			 run, expressed as seconds since January 1, 1970,
			 00:00 Coordinated Universal Time, preceded by a

		   $<&lt&lt&lt;	 Replaced by text read by at from the standard input
			 (that is, the commands provided to at to be run in
			 the job).

	   +  When a job is submitted to queue queue, at uses the file
	      /var/adm/cron/.proto.queue as the prototype file if it exists.
	      Otherwise it uses the file /var/adm/cron/.proto.

      The following .proto file creates commands to change the current
      directory, file size limit, and umask in the job to their respective

      values as they existed when at was originally run.  These commands are
      inserted before the commands in the job:

	   cd $d
	   ulimit $l
	   umask $m

      at(1), queuedefs(4).
