Perl One Liner: Crontab

ol

I was searching for easy way to enable or disable Crontab entries. I found below at serverfault.com

To disable crontab -l | perl -nle 's/^([^#])/# $1/;print' | crontab

To enable crontab -l | perl -nle 's/^#\s*([0-9*])/$1/;print' | crontab

Simple and easy to use when you have many lines in crontab to manipulate.
