remove filename prefix - UNIX for Dummies Questions & Answers

peter.herlihy · #1 (**permalink**) 07-10-2002

I've got a bunch of files called oldabc, olddef etc.

i want to copy these to be abc, def....

I can do this with file extensions....but can get the logic to work for prefixes. All the files I am interested in have a prefix of 'old'.

This loop is no good for me....it looks at the content of the files...rather than changing the filename.

for files in `ls *fmt`;
do
newfilename="cut -c4-50 $files";
cp $files $newfilename;
done

How do I get it to look at the filename and change it - rather than the content of the file?

Code:

for files in `ls *fmt`
do
newfilename=`echo $files | cut -c4-`
cp $files $newfilename
done
