This folder contains crontab files and templates. Crontab define a schedule for automated activities that are executed with the 'crond' scheduler system.
Documentation on the 'crond' scheduler can be found with: man cron
Files here in /p4/common/etc/cron.d should be named like so: crontab.$USER.$(HOSTNAME -s) (or this, which is equivalent: crontab.$(id -n -u).${HOSTNAME%%.*}).
That is, crontab.operating_system_user_id.short_hostname
Sample: crontab.perforce.bos-helix-01
If you are using the 'Tight Ship' style management of the Helix Management System (HMS), the suggested naming convention above is required.
For more information on HMS, see Helix Management System.

Renamed crontab templates files to be template.* rather than *.template. This is an 'optimize for lazy' tweak, since if we use a prefix, then the actual crontab files named of the form crontab.$USER.${HOSTNAME%%.*} won't have command line completion conficts with the templates. Added a ReadMe.md file describing the suggested (and with HMS required) naming convention for crontab files. Added a command summary doc for the sdp_sync.sh script that manages crontab files in a tight ship deployment. The reference to this file from the ReadMe.md file won't work now with this change in the dev branch, but will work once promoted to main. |
