Hopefully you can figure it out now.

EDIT: Also, you shold NEVER use ls output in a script. It's meant for human reading only.

Use this instead to loop over files in a directory:

Code:

for FILE in *
do
    # stuff
done

Ok am mega confused now sorry
The guy in this post made that code I posted above
It was for renaming alot files and it worked just fine

Only the start of the file names have changed everything else Ive wrote in this thread still is the same

Am really really new to linux and you say never use output, I have no idea what your talking about sorry :C
Thanks for the help btw

I didn't say "never use output", I said "never use the output of the ls command for anything but reading by humans.".

Maybe you should check out the LinuxCommand tutorial (there's a link to it in my sig). It has a very nice section on scripting.

I thought it might of been just a simple change in that .sh file was all

Thanks I'll have a look when work is over

Also I tryed this and it did nothing apart from in putty it went to the next line
plus I had to restart putty as I couldn't type again

How do you think that will automatically do what you want without specifying the input and output files?

(BTW, press Ctrl+C to kill it. You don't need to restart the terminal).

Did you read the LinuxCommand tutorial, or at least try to learn or understand anything?

Actually, it is a simple change in the .sh file.

Thanks for that
I did say "Thanks I'll have a look when work is over" It was just a quick test

If I understand your problem correctly, then this should work:

Code:

#!/bin/bash

find $PWD -type d | grep -v "^${PWD}$" | \
while read directory
do
  for file in "$directory"/*
  do
    mv -n "$file" "$(echo "$file" | sed -r 's/[a-zA-Z0-9]+\.[a-z]+[ \t]+[a-zA-Z0-9]+\.[a-z]+[ \t]+-[ \t]+[0-9]+[ \t]+-[ \t]+(.*)/\1/')"
  done
done

  done
done
