i never done this before so i may ask a few questions.
what does locking a file mean?
should i use "flock" to lock the file?
should i use perl or a shell script?
I did write a small script that started out
with something like
!#/usr/bin/perl
if blah /usr/local/program
/usr/local/anotherprogram
/usr/bin/program3
fi
that is my whole extent to programming although if it was 68xx assembly
then I could do wonders...I love talking directly to hardware.
