Important cron gotcha: Cron not being updated.
May 12, 2011
I was recently caught out by a crontab running even after I had edited the crontab and commented out the line.
I used VIM and edited the file followed by a
:w command but the cron was not being updated.
It turns out that the crontab isn't updated until the editor is closed too. As I still had the file open, the crontab was unchanged.
Hopefully this will help someone out in the future.
