UNIX for Dummies Questions & Answers

Hi there,

I have a folder full of pdf's and I've run a compression on the to reduce the size, the output of the compress places a '-o' in the name of the file.

Before 12345.pdf
After 12345-o.pdf

Now I've got around 50000 files that I need to change back to the previous name, is there a script that can be used to do this?

Any help is much appriciated.

Regards
Kees

in Unix.

there is no command for renaming

use can mv command

mv oldfilename newfilename

Try some things like

Code:

#!/bin/ksh

INPUT_DIR="/home/"
for file in $(ls $INPUT_DIR/*-o.pdf)
do
        new_file=$(echo ${file%%-o.pdf})
        new_file=${new_file}.pdf
        mv $file $new_file
done

Code:

ls *o.pdf  | while read file
do
 mv "$file" `echo $file | sed 's/-o//'`
done
