I need help in writing please

Also, if I use "print" within perl to the dump a executable command to
the monitor, will the process be executed and the perl will wait
before it throws the next one to screen?

First, try to help yourself.

If you want the script written for you, I am sure there will be a
few people who'd do it for $500. If you want tech support to go with
that, maybe $750. If you would like me to write it, the rate goes up
to $2500.

If you are willing to pay for the job, then post an announcement at
http://jobs.perl.org/

Otherwise, try to solve your problem first on your own (make sure to
consult the various resources available to you) and then post
concrete questions here.

Ok, what do you have so far? Show us your current code, explain what it
is supposed to do (you got that part already), what it is actually
doing, or where you are stuck. I am sure someone will be happy to show
you how to get unstuck.

This sentence doesn't compute. I have absolutely no idea what you are
talking about.

print() has nothing to do with process control. Where did you get that
idea?

Hi,

Rui Macial has already told you: "Do not let others do your homework!"
Try some coding first.
Moreover, many neebies have asked the same question, you will find
helpful replies.

This works at least in ksh/bash: (no shell builtins for var-substitution)

while read file
do
f_short=$(echo $file | cut -d . -f 1) # strip the .txt suffix
C_PROGRAM $file > "$.mp3"
done < list1

--jk

Newbie should begin writing a simple script in Perl.

Newbie should post the broken code here when you get stuck.

Then we will help newbie fix the broken code.
