Renaming thingy

Renaming thingy

[meino.cramer]

Hi,

 I have a directory tree with different directories
 on different levels.
 There are files scattered around there, some of then
 are named *.JPG.
 I want to rename them, starting at the root of that tree
 to *.jpg.
 Furthermore some of the directories contain spaces in
 their names. I want to replace the spaces by underscores.

 Is there a compact way to accomplish this with zsh?

 Thanks a lot for any helpful hint in advance!
 Keep zshing!

Do it in two stages.


autoload -U zmv
zmv '(**/)(*).JPG' '$1$2.jpg'
zmv '(**/)(*)(#q/)' '$1${2// /_}'


This is guaranteed to be depth first.  So first it renames .JPG files,
then it renames directories starting with the end component.  This
should mean all the generated "mv"s operate on existing file names.

I think.
