Shell Programming and Scripting

How about this

Code:

for i in `ls [0-9]-*.txt`
do
mv "$i" "0${i}"
done

It is doing

Code:

mv 4-track4.txt 04-track4.txt
mv 5-track5.txt 05-track5.txt

But now i need reverse.

Code:

04-track4.txt to 4-track4.txt
05-track5.txt to  5-track5.txt

Please confirm below code is fine?

Code:

for i in `ls [0-9]-*.txt`
do
#echo mv "$i" "0${i}"
echo mv  "0${i}" "$i"
done

This is getting silly... You have been given all the needed information to do what is asked so I am closing the thread, if you reoppen again a new thread on the subject I will get angry...
Once given a solution, we here understand you will be testing it completely and ask again if there are doubts in your understanding on what is going on, e.g. you changed some parameters to see if you understood and are in mesure to say what you expected but did not produce...
Why dont you test your code yourself then ask what is wrong if you cant sort it out yourself, the way you are using the forum gives to the public the very strong impression you are not willing to learn, therefore why should we bother loosing our time here?
