NAME

crontabs - configuration and scripts for running periodical jobs

SYNOPSIS

run-parts <directory>

DESCRIPTION

Crontabs is historical name for run-parts script and system crontab. Run-parts runs all executables in the specified directory. The execution of files can be allowed or denied by creating file jobs.allow
or jobs.deny which worked similar as other allow/deny config files. The file must be created in the specified directory.

Historically the crontab file contained configuration which called run-parts on files in cron.{daily,weekly,monthly} directories. These jobs are now run indirectly through anacron to prevent conflicts between cron and anacron. That means the anacron package has to be installed if the jobs in these directories should be running. Refer to the anacron(8) how to limit the time of day of the job execution.

EXAMPLE

/etc/cron.daily/jobs.deny could contain for example 0logwatch which forbid execution of this script.
