proto(4)                                                    proto(4)


       NAME
             proto - prototype job file for at

       SYNOPSIS
             /etc/cron.d/.proto
             /etc/cron.d/.proto.queue

       DESCRIPTION
             When a job is submitted to at or batch, (see at (1)) the job
             is constructed as a shell script.  As part of this process, at
             reads a prototype file, and uses it in the shell script.  The
             default .proto file is:

                   #ident  "@(#)adm:.proto 1.2"
                   cd $d
                   ulimit $l
                   umask $m
                   $<

             Text from the prototype file is copied to the shell script
             file, except for special variables that are replaced by other
             text:

                   $d    is replaced by the current directory
                   $l    is replaced by the current file size limit (see
                         ulimit (2))
                   $m    is replaced by the current umask (see umask (2))
                   $t    is replaced by the time at which the job should be
                         run.  (Time is expressed as seconds since January
                         1, 1970, 00:00 Greenwich Mean Time and is preceded
                         by a colon.)
                   $<    is replaced by text read by at from the standard
                         input (that is, the commands provided to at to be
                         run in the job)

             When this default .proto file is used, the current directory
             is changed to the current directory at the time at was run,
             the ulimit is changed to the ulimit at the time at was run,
             and the umask is changed to the umask at the time at was run.

             If the job is submitted in queue queue, at uses the file
             /etc/cron.d/.proto.queue as the prototype file if it exists,
             otherwise it will use the file /etc/cron.d/.proto.
