Rename recursively

unihiekka · 05-23-2010, 07:31 AM

How could I rename (lots of) files (recursively from the pwd) from *.jpg to cover.jpg? I have many different cover art files for my mp3s, but I want to rename them all to cover.jpg (in each folder). Thanks!

Hi unihiekka: This LQ post should help.

Hi,

for THISFILE in `find /mp3/base/dir/ -type f -name "*.jpg"`; do echo ${THISFILE} ${THISFILE%/*}"/cover.jpg"; done

This looks for jpg files in /mp3/base/dir/ (substitute with your mp3 base directory) and renames them to cover.jpg

If there are more the one jpg files in the same directory all will be renamed to cover.jpg and you will end up with 1 jpg file!! I do assume that all jpg's are in seperate dirs (one jpg per album).

I also assume that you have a base directory for mp3's. Something like this (names may differ):
/multimedia/mp3
/multimedia/mp3/Bauhaus
/multimedia/mp3/Japan

If a test run succeeds, change echo to mv.

Hope this helps.

Not in this case, although some of the techniques used are somewhat similar.

The thread you refer to changes JPG to jpg, which is easier then changing xxxx.jpg to cover.jpg.

Thanks for that. Another question. Somehow there are some files that are hidden, so they are of the form ".*.jpg". How would I go about changing that line to accommodate for that difference (I know that at least I should change the "*.jpg" to ".*.jpg", but then I would like the files to become normal, not hidden. That alone won't do, because then it cannot stat the files...) Any help much appreciated.

Hi,

Did you try my command? It should pick up on the dot files as well:

Code:

/tmp/Temp $ ls -lAR
.:
total 16
drwxr-x--- 2 druuna internet 4096 May 23 19:52 a
drwxr-x--- 2 druuna internet 4096 May 23 19:52 b
drwxr-x--- 2 druuna internet 4096 May 23 19:52 c
drwxr-x--- 2 druuna internet 4096 May 23 19:52 d

./a:
total 0
-rw-r----- 1 druuna internet 0 May 23 19:46 .aaa.jpg

./b:
total 0
-rw-r----- 1 druuna internet 0 May 23 19:47 .bbb.jpg

./c:
total 0
-rw-r----- 1 druuna internet 0 May 23 19:47 zzz.jpg

./d:
total 0
-rw-r----- 1 druuna internet 0 May 23 19:52 zzz.jpg
druuna /tmp/Temp $ 

/tmp/Temp $ for THISFILE in `find /tmp/Temp/ -type f -name "*.jpg"`; do echo ${THISFILE} ${THISFILE%/*}"/cover.jpg"; done
/tmp/Temp/c/zzz.jpg /tmp/Temp/c/cover.jpg
/tmp/Temp/b/.bbb.jpg /tmp/Temp/b/cover.jpg
/tmp/Temp/d/zzz.jpg /tmp/Temp/d/cover.jpg
/tmp/Temp/a/.aaa.jpg /tmp/Temp/a/cover.jpg
druuna /tmp/Temp $

Bold lines are the dot files.

Hope this helps.

Hi,

try

Code:

shopt -s dotglob

and then run the command in the same shell again. Should now also match files that start with a dot.

Yes, druuna, you are right. I'm sorry. I did not see the hidden files in the list. There is however a catch. When I use echo, no problem. When I replace it with mv, it says cannot stat, probably because there are spaces in the folder names. Can that be an issue?

Absolutely. You need to quote the names with spaces in them.

Code:

for THISFILE in `find /tmp/Temp/ -type f -name "*.jpg"`; do echo "${THISFILE}" "${THISFILE%/*}/cover.jpg"; done

... that *should* work (untested).

druuna · 05-26-2010, 01:55 AM

Hi,

A possible solution for the spaces would be to change this:

echo ${THISFILE} ${THISFILE%/*}"/cover.jpg"

into:

echo "${THISFILE}" "${THISFILE%/*}/cover.jpg"

Hope this helps.
