Help required from awk/sed boffins

Hi all,
I bought a media player for my sister. It does not agree with the .img file extension. It has to be .iso for it to work.
I did this:
Code: Select all
find . -iname '*.img' -exec mv {} {}.iso \;
It works, but it is not neat. I do not like my files having the extension .img.iso...
I have seen some fancy sed stuff here lately, mainly by gordon, I think (I might be wrong, one of the new guys)
Anyone happy to give me some pointers?
Many thanks in advance!

Hi,
If you're trying to replace the '.img' extension, then try
Code: Select all
for file in `find . -iname '*.img'`; do mv $file ${file/.img/.iso}; done

EDIT: Too tired to think. First try was way incorrect, second try misspelled. I'm going to bed now

Thank you both!
Rename, eh? I never knew such a command existed. Why did I ever have to learn about mv in the first place?
EDIT:
To answer my own question: probably due to my Solaris background...

Hmm, rename was a new one to me as well.
I forgot to mention I usually echo the result to console, instead of execute them on the go. That way I get a chance of verifying I'm executing the command I had in mind (I know to well what damage a brain fart can do). So ,try
Code: Select all
for file in `find . -iname '*.img'`; do echo "mv $file ${file/.img/.iso}"; done
(or use rename command) Mark it, then paste it, and now you got no one to blame but yourself

Hehe,
I usually use ls with the find -exec command before I commit myself as well

Rename is a python command I believe (I.e. not native bash). It only works with regular expressions. You can't just do

I could not get any of the suggested solutions to work flawlessly.
rename did not seem to work at all as suggested.
Johan's little script worked, but for some reason missed 3 directories (perhaps because of spaces in directory/file names?)
Anyhoo, I tweaked the remaining stuff manually now, so all sorted.
Thanks again!
