# Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any'). # # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # # For more information see the manual pages of crontab(5) and cron(8) # # m h dom mon dow command # ######################################################### # # string meaning # @reboot Run once, at startup. # @yearly Run once a year, “0 0 1 1 *”. # @annually (same as @yearly) # @monthly Run once a month, “0 0 1 * *”. # @weekly Run once a week, i.e. Sunday at 00:00, “0 0 * * 0”. # @daily Run once a day, “0 0 * * *”. # @midnight (same as @daily) # @hourly Run once an hour, “0 * * * *”. # #mm hh Mday Mon Dow CMD # minute, hour, month-day month DayofW CMD #………………………………….Minute of the hour #| …………………………..Hour in the day (0..23) #| | …………………….Day of month, 1..31 (mon,tue,wed) #| | | ……………..Month (1.12) Jan, Feb..
