ANACRONTAB(5)						       Anacron Users' Manual						     ANACRONTAB(5)

NAME

       /etc/anacrontab - configuration file for anacron

DESCRIPTION

       The file /etc/anacrontab describes the jobs controlled by anacron(8).  Its lines can be of three kinds:	job-description lines, environment
       assignments, or empty lines.

       Job-description lines are of one of these two forms:

	  period  delay  job-identifier  command

	  @period_name delay job-identify command

       The period is specified in days, the delay in minutes.  The job-identifier can contain any non-blank character, except slashes.	It is used
       to  identify  the  job in Anacron messages, and as the name for the job's timestamp file.  The command can be any shell command. The fields
       can be separated by blank spaces or tabs.  The period_name can only be set to monthly at the present time. This will ensure jobs  are  only
       run once a month, no matter the number of days in this month, or the previous month.

       Environment assignment lines are of the form:

	  VAR = VALUE

       Spaces  around  VAR  are removed.  No spaces around VALUE are allowed (unless you want them to be part of the value).  The assignment takes
       effect from the next line to the end of the file, or to the next assignment of the same variable.

       Empty lines are either blank lines, line containing white-space only, or lines with white-space followed by a '#' followed by an  arbitrary
       comment.

       You can continue a line onto the next line by ending it with a ''.
