Hi!
I’ve a cronjob that I don’t want to be concurrent but it needs to leave a long-running process after it does it’s job that I set up with a nohup command.
The deal is that once the script has setup the lock doesn’t get released so any further calls to the script just get ignored.
Is there a better alternative/flag I’d use? I couldn’t discern much from the flock or nohup man pages.
Solved: With bit more fiddling found the - u flag on the flock man page. You can unlock yourself at the very end of the script.
the
f
stands for file. The c manpage has some details on how it works: https://www.man7.org/linux/man-pages/man2/flock.2.html
