A Unix Utility You Should Know About: Pipe Viewer

mmv (moves multiple files based on a simple pattern replacement language). Example:

    mmv "*.mp3" "old_#1.mp3"

prefixes all files in the current directory ending with .mp3 with 'old_'. Btw., the quotes around the arguments are necesssary because mmv uses some of the same metacharacters as the shell does.

Multiple substitutions are allowed, e.g.:

    $ mmv "*.*" "#1___#2"

renames blub.xyz to blub___xyz.

Zsh has a module called zmv which lets you do things like:

zmv '(??)-(*).mp3' '$1 - ${(C)2:gs/_/ }.mp3'

Which would change "01-foo_bar_baz.mp3" into "01 - Foo Bar Baz.mp3"

I've been looking for something like that for years!

I commonly use qmv (from renameutils):

qmv, qcp - Rename or copy files quickly, editing the file names in a text editor

Found nothing better for bulk renames because you get to use all the pattern/replace power of your favorite editor instead of learning some wierd specialized grammar through trial & error.

This is how to remove all spaces from mp3 filenames using vim:

qmv -f do *.mp3

:%s/ /_/g

:wq

for Emacs users, there is wdired mode, which makes a directory listing editable just like a normal Emacs buffer.

A lot of what I find lacking in a standard terminal, Emacs makes up for with its shell and terminal emulators. I find that an editable buffer with the contents of my entire session to be eminently powerful when combined with keyboard macros and the search/replace commands.

Has anyone had any luck getting this to compile for OS X (Leopard)? make seems to fail on an error for me.

Andrew Myers has a shell script called mvsed that does something similar, using sed to specify the patterns.

Found it: http://www.cs.cornell.edu/andru/useful.html

There's a 'rename' script that comes with Perl that also does this, which may be useful if you want some really fancy renames. E.g. rename '$_=lc' *.MP3 to change case to lowercase.

Anyone know where to find a source tarball that compiles under Leopard? All I've found is a bunch of precompiled Linux RPMs...

Update your MacPorts. It was just added:

hm - no source tarball, but perhaps others find this Leopard binary useful:

(including man pages etc.) Caveat: I didn't try it myself (I don't have Leopard).
