Please be more specific. Every time you encounter an error and ask for help, tell us the content of the script, the exact command line used and the copy/pasted output and errors you see in the terminal. And please use the code tags to embed the code, to preserve spaces, indentation and so on (code tags are those you get if you select some text and click on the "#" button in Advanced Mode).

when i run this sample script on with my original puppy disto it stops at line 4 and keeps looping an error message over and over again. i put a second install on my netbook and run the sample script, it runs good. tried the sample script on 2 different machines (same disto puppy 4.1)and no problems. something is corrupt in the install. i'm going to uninstall that distro.

sample script:

#!/bin/bash
number=0
until [ $number -ge 100 ]
do
echo $number
((number++))
done

do
    nohup transcribe $rec &    # nohup plus & enables you to logout of this session without breaking it
done

yes that is what i am trying to do. i will try this routine in the next couple of days i am at work right now. also i messed around with these 2 lines and they both worked for what i want to do. they would execute 1 line at a time and stop at the last line.

transcribe $(sed -n -e '/1/,/100/p' save.txt) &

transcribe $(head -n100 save.txt) &

thanks

Is bash a symlink to another shell, or is it really bash -and which version?
If your loop is sticking try using a different syntax like this:

Code:

/bin/bash
IFS="
"
while read line ; do
  transcribe "$line" &
done <save.txt
