Unix Scripts

Renaming all files in a directory tree

Sometimes you want to rename every single files in a directory tree. I had this issue when I transfered a huge numbers of digital pictures to my linux box. I realized that Microsoft Windows was naming imported digital pictures with a space in the name making it very difficult to rename in batch.
This little script allows you to rename every single file of a directory tree including files with funny characters and spaces with filename like pictures0001.jpg.
Here is the script :

#!/bin/bash

let COUNT=0

find /home/boismarj/images/AnneAlex -name '*.jpg' -exec ls -li {} \; | sed 's/\/Picture.*.jpg//' | awk '{print $1"|"$10}' > file.txt
for lines in `cat file.txt`
do

INODE=`echo $lines | awk -F"|" '{print $1}'`
PATHTOIMG=`echo $lines | awk -F"|" '{print $2}'`

if [[ $COUNT -lt 10 ]]
then
DIGIT="00"
else if [[ $COUNT -lt 100 ]]
then
DIGIT="0"
else if [[ $COUNT -lt 1000 ]]
then
DIGIT=""
fi
fi
fi

echo $INODE --> $PATHTOIMG/image$DIGIT$COUNT.jpg
find . -inum $INODE -exec mv {} $PATHTOIMG/image$DIGIT$COUNT.jpg \;
let COUNT=COUNT+1
done
