automated bash script execution using cron

  • 772

I have been trying to use the cron package for scheduled bash script execution as is generally intended, and have found almost everything I need via this resource here

However the part I was unable to find, was the means for which I can set a beginning and end for a particular cron schedule to be conditional, ie I suppose I wanted a particular cron job to only be executed in march daily, and to then continue in april if say some binary variable (whose value is determined from some sort of assessment of the cron job's march output) is 1, and for the the cron job to be terminated until further notice if it's value is 0.

I apologise if my phrasing is unclear, constructive criticism is appreciated.

    You can put variables in the crontab file, so you can have

    EXECUTE_JOB=1

    Then implement the condition with this /bin/sh construct

    * * * * * [ "$EXECUTE_JOB" = "1" ] && your existing job here

    Then, on April 1, you can adjust the value of that variable accordingly
