Many times admins forget the field order of the crontab file and alway reference the man pages over-and-over. Make your life easy. Just put the field definitions in your crontab file and comment (#) the lines out so the crontab file ignores it. # minute (0-59), # | hour (0-23), # | | day of the month (1-31), # | | | month of the year (1-12), # | | | | day of the week (0-6 with 0=Sunday). # | | | | | commands 3 2 * * 0,6 /some/command/to/run 3 2 * * 1-5 /another/command/to/run
