anacrontab(5) -- Linux man page
NAME/etc/anacrontab - configuration file for anacron
DESCRIPTIONThe 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 the form:
period delay job-identifier 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.
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.
