Thank you all for your quick reply.
I followed Rob's way and it was fairly easy to do. I had to change a bit
something but it worked.
The rename script that I used is:
- ------cut here------
#!/bin/sh
ls *\ * | while read OLD ; do
NEW=`echo $OLD | tr ' ' _`
mv -i "$OLD" $NEW
done
- -----cut here----------
As u notice I had to add the semicolon " " in the $OLD variable because
otherwise the mv was complaining. So this was a nice and fast way to do
it. Thank you all people for your quick reply!!
