[clug-talk] file locking in bash?

[Roy Souther]

Is there anyway to do file locking in a bash script? I need to remove
the race hazard from a script that has multiple running instances per
user, each trying to make changes to a text file. I need to get
exclusive access to a file and make the other instances wait their turn.

Any ideas? Flock is supported by more advances script engines like Perl
but flock seems to be beyond the ability of a simple shell like bash.
