NAME
proto - prototype job file for at(1)
SYNOPSIS
/var/adm/cron/.proto
/var/adm/cron/.proto.
queue
DESCRIPTION
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 ulimit(2)).
$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 Janu-
ary 1, 1970, 00:00 Coordinated Universal Time, preceded by a colon.
$< 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
.
EXAMPLES
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
$<
