find mp3- and m4a-files
Hi,

I will find all mp3 and m4a files on a certain volume with regular expressions. The following command will not work (I am new to this)
Code:
find /Volumes/music/ -iname '*.m[p34a]'

Does anyone can help me with the right syntax?

PS Mac OS X

Not sure about Mac OS X but with GNU find you would need something like this:

Code:
find  /Volumes/music/ -regextype posix-extended -iregex '.*\.mp[34]a?'

And this one should work with most (all?) find implementations:

Code:
find /Volumes/music/ -name '*.[Mm][Pp]3' -o -name '*.[Mm][Pp]4[Aa]'

-iname is used with wildcards, -iregex with regular expressions.

Something like this would "partially" work in MacOS (file names such as "file.m43" would also match the pattern):

Code:
find /Volumes/music -iname "*.m[p4][3a]"

With regexp:

Code:
find /Volumes/music -iregex '.*\.m[p4][3a]$'
