Anyone have a script to schedule a job and remove once run ? 1

[Tison]

Does anyone have a clever idea on how to remove an entry from cron once a job has run ?
What I want to achieve is to schedule a job via cron and then either remove or hash it once it has run.

There probably is a way, but doesn't at suit this scenario?

Oops - sorry PHV, we're posting at the same time.

Easiest way would be to run the job once via cron and set a file (temp file). The next time the job runs from cron the script should llok for the flag and not run....then you can remove from cron at your lesure....

have you script remove itself when complete

add this to the bottom of your script.

crontab -l | egrep -v "myscript" > /tmp/newcron
crontab /tmp/newcron

Try using "at" - it lets you schedule a job to be run ONCE, and with a little creativity, you can have it reschedule itself so that it effectively works like cron.
