batch renaming of files

Hi,
I've got a number of photos that need changing their names.
What I need is a short script to change the names to 01.jpg, 02.jpg, etc.
I've been trying to do it with 'rename' and 'move' but I can't get it right.

Also, I've started learning python, and am courious how it would look in python.

thanks

Hello
Try something like this, it should work fine but I do not
have time to try it out.

Remember to try it on some dummy files first.

Quote:

#!/bin/sh
loop=1;

IFS='
'
for FILE in `ls -t -r pictures`;
do

#Get file extension
EXTENSION=`echo $FILE | sed 's/.*[.]//g'`

NEW_NAME=`$loop.$EXTENSION`

let loop++;

mv pictures/$FILE pictures/$NEW_NAME

done

Thanks

however, I get the following error:

Code:

loop=1;



#!/bin/sh

IFS='

'

for FILE in `ls -t -r zdjecia`;

do



#Get file extension

EXTENSION=`echo $FILE | sed 's/.*[.]//g'`



NEW_NAME=`$loop.$EXTENSION`



let loop++;



mv zdjecia/$FILE zdjecia/$NEW_NAME



done

Code:

mv: `zdjecia/dsc_0546.jpg' and `zdjecia/dsc_0546.jpg' are the same file

./skrypt: line 13: 65.jpg: command not found

mv: `zdjecia/dsc_0545.jpg' and `zdjecia/dsc_0545.jpg' are the same file

./skrypt: line 13: 66.jpg: command not found

mv: `zdjecia/dsc_0542.jpg' and `zdjecia/dsc_0542.jpg' are the same file

./skrypt: line 13: 67.jpg: command not found

mv: `zdjecia/dsc_0539.jpg' and `zdjecia/dsc_0539.jpg' are the same file

./skrypt: line 13: 68.jpg: command not found

mv: `zdjecia/dsc_0498a.jpg' and `zdjecia/dsc_0498a.jpg' are the same file

./skrypt: line 13: 69.jpg: command not found

mv: `zdjecia/dsc_0438.jpg' and `zdjecia/dsc_0438.jpg' are the same file

./skrypt: line 13: 70.jpg: command not found

mv: `zdjecia/dsc_0420.jpg' and `zdjecia/dsc_0420.jpg' are the same file

./skrypt: line 13: 71.jpg: command not found

mv: `zdjecia/dsc_0419.jpg' and `zdjecia/dsc_0419.jpg' are the same file

./skrypt: line 13: 72.jpg: command not found

mv: `zdjecia/dsc_0417.jpg' and `zdjecia/dsc_0417.jpg' are the same file

./skrypt: line 13: 73.jpg: command not found

mv: `zdjecia/dsc_0982.jpg' and `zdjecia/dsc_0982.jpg' are the same file

and so on...

any ideas?
thank you

Right, the backticks should not be there.
Remove the backticks and it will work.

Replace

NEW_NAME=`$loop.$EXTENSION`

with

NEW_NAME=$loop.$EXTENSION

Works perfect, thanks

The obligatory one-liner:

Code:

j=1;for i in *;do echo mv $i $j.jpg;j=$((j+1));done

Remove the echo do let it do the actual work.

Code:

import os

os.chdir("where")

for num,files in enumerate(glob.glob("*.jpg")):

    s=os.path.splitext(files)

    fname,ext=s[0],s[1]

    if num +1  < 10: n=str(num+1).zfill(2)    

    os.rename(files,s[0]+str(n)+s[1])

The requirement needs to include a 0 infront of single digit numbers.

Works fine so long as all pictures are jpg files. If there is a mix of jpg and jpeg the code will not work.
