What is the effect of exit codes in the script code section? Does an
exit 0(1,2...) exit just the subshell or the entire script? I am worried
by a lock being left in place by one of these.
The > redirector is redirecting file descriptor 200 to the file you are
specifying. In this case, I think that the choice of 200 is arbitrary.
As long as you redirect the same file descriptor that you pass to flock,
then the number shouldn't matter (though don't choose stdout :D)
So it is not actually creating the lock file? So I must make sure the
lock file exists in advance?
Kindest Regards
