+This page describes the basic use of cron on HCoop systems.\r
+\r
+[[TableOfContents]]\r
+\r
+= Prerequisites =\r
+\r
+It is very important that you read the [:MemberManual/RunningUnattendedCommands:Running Unattended Commands page] to understand the general idea of how to run unattended commands on Mire.\r
+\r
+= Making a cron configuration file =\r
+\r
+Cron needs a special configuration file to tell it how to operate. It is suggested that this file be called {{{~/.crontab}}}, though it can have any name.\r
+\r
+For an explanation of the format of this file, run:\r
+\r
+{{{\r
+man 5 crontab\r
+}}}\r
+\r
+= Activating your cron configuration =\r
+\r
+Once you are satisfied with your setup, run the following command to activate your changes, assuming that your configuration file is called {{{~/.crontab}}}:\r
+\r
+{{{\r
+crontab ~/.crontab\r
+}}}\r
+\r
+= Examples =\r
+\r
+One convention for making scripts to run commands in their own PAG, as specified by the [:MemberManual/RunningUnattendedCommands:Running Unattended Commands page], is to create the {{{~/scripts}}} directory, and place your scripts there. Then, make a cron configuration file that looks something like this.\r
+\r
+{{{\r
+09 0 * * 0 ~/scripts/clean-mail\r
+11 0 * * 0 ~/scripts/remove-tmp\r
+12 0 * * 0 ~/scripts/weekly-comment-check\r
+*/10 * * * * ~/scripts/make-git-projects\r
+}}}\r
