Comment out a specific crontab job
Let's say we have many jobs in crontab and we'd like to comment out this one:
*/10 * * * * /usr/share/mapstats/mapstats
- Locally:
crontab -l | sed 's/.*\usr\/share\/mapstats\/mapstats/#&/' | crontab -
- Remotely on multiple servers, example:
for i in 172.16.16.{1..50}; do ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $i "crontab -l | sed 's/.*\usr\/share\/mapstats\/mapstats/#&/' | crontab -" ; done
Uncomment the job from our previous example
crontab -l | sed '/.*\usr\/share\/mapstats\/mapstats/s/#//' | crontab -
