bash file rename half solved

[rcr1991]

I am a complete novice.

The following cut command works perfectly to trim a filename and output to the text file the new, correct filename.

What I cannot figure out is how to MV the filename from the OLD name to the NEW name which is the output of the CUT command?

Suggestions?

ls -1 *pdf* | cut -f4 -d_ >list.txt

Thanks,

Rob

Hi Rcr,
Is something like this what your interested in?

for original in *.pdf
do
    newName=$( echo $original | cut -f4 -d_ )
    mv $original $newName
done
