Hi,

do you want to change only the name, or do you want to actually change the contents ? If you want to change the contents, I suggest you use perl. And you you need to understand the format of the prn file, which I'm not familiar with.

If prn is a binary file, you need to other tools than shell commands to do the job.

Hi,

try this :

for FILE in $(find -name "*.txt")
do
mv $FILE $(dirname $FILE )/$(basename $FILE | cut -d. -f1)
done

Right,

try this.

#$/bin/sh

for i in $(ls /your_directory_with_txt_files/*.txt)
do
mv $i /your_directory_with_txt_files/$(basename $i .txt).prn
done

Or you could give the directory as an argument to the script, and replace your_directory_with_txt_files with $1

scripting is fun (ok... i'm sick but i enjoy it). If you'd like to get some books on it I would recommend.

"Korn Shell Programming by example" by O'Brien, Pitts

&

"sed & awk" by Dougherty & Robbins

for your problem I would write this script:

#! /usr/bin/ksh
for i in $(ls /path/to/files)
do
file=$(echo $i | sed 's/.txt//g')
mv $file $file.txt
done
