Assuming files with an .mp3 extension, and a length limit of 42 
characters (including the extension), this should do it:

find . -name "*.mp3" | rename -v \
's|(.*/)(.*)(\.mp3)|$1 . substr($2,0,38) . $3|e'


providing you find yourself a copy of the previously mentioned 'rename' 
Perl script.

If you can't find the script or don't have Perl on the box, you might 
want to investigate 'awk'. It's the next best tool for this kind of 
string manipulation. You could pipe the output of 'find' to it.

'find' itself supports a printf action in which you can specify the 
formatting of file names and paths, including their widths, but like the 
C printf() it doesn't truncate strings that exceed the specified width, 
it only pads the fields with spaces.
