| Subj: || || Unix file locking |
| From: || || Jeremy Christiansen |
I'm writing some shell scripts that will be run on our Ap-node. Many of these scripts will be run simultaneously and also access a set
of shared files. I would like to know if there is a way for me to lock a file so that when one script updates it all other scripts will be
blocked from reading/writing to it. I am familiar with the "lockfile" technique but am wondering if there is just a simple command that
will lock/unlock a file for me.
