without changing the name of the file...

i have a group of .JPG files in with a directory of .jpg files, i just want to mv the .JPG to .jpg is there a way to do this without renaming or touching every single .JPG file?

should cover you, and if that's too indepth, you should be able to take a few pointers from my script (or the other exampels)

Here's one way to do it...

Code:

#!/bin/bash
dir=/home/images
ls $dir | grep -e "JPG" | \
while read i; do
j=`echo -n "$i" | sed -e 's/JPG$/jpg/'`
mv "$dir/$i" "$dir/$j"
done

ok that is a bit more complicated then i was thinking, hoping it would be, how do i do that? just log in as root and type !/bin/bash and hit the enter key after each line you have...???

mega newbie to any kind of scripting.

no that's a bash script. copy the verbatim into a file, and run it.

Guys... overkill...

Code:

rename ".JPG" ".jpg" *.JPG

That is, unless I'm overlooking something in the problem.

Well poo!

guess I got caught up in the script thingy. That actually had a more meaningful use previously and I just changed a few things to make it fit.

Hehehe... honestly, I thought I was going to receive a swift back-hand response for my insolence. I kept thinking, "There has got to be a reason they're suggesting a script... maybe a follow-up question from a previous thread??"

I've seen messages from you and acid_kewpie before, and you guys pretty much nail things right on the head: straight and to the point. So I was prepared to nurse my ego because there had to be something I was missing
