A more robust approach which preserves space characters in filenames and works for any number of files is:
That is less robust than my suggestion. It will fail if there is a newline (heaven forbid!) in a file name. It also uses an unnecessary external command.
It will also fail if there is leading or trailing whitespace in any filenames. Or if there are any backslashes.
The syntax I used will work no matter what pathological characters are in the filenames.

Code:
#!/bin/sh
ls -1 mytest.sh | while read filename
The -1 is not needed because the output of ls is not going to a terminal.
I think you meant:
Code:
ls test | while IFS= read -r filename

do
sed -e 's/bob/manny/g' "${filename}" > "${filename}.0"
mv "${filename}.0" "${filename}"
You should check that sed succeeded before wiping the original file:
Code:
sed -e 's/bob/manny/g' "${filename}" > "${filename}.0" &&
mv "${filename}.0" "${filename}"[/QUOTE]

mp3::tag::file
MP3::Tag::File(3pm) User Contributed Perl Documentation MP3::Tag::File(3pm)NAME
MP3::Tag::File - Module for reading / writing files
SYNOPSIS
my $mp3 = MP3::Tag->new($filename);
($title, $artist, $no, $album, $year) = $mp3->parse_filename();
see MP3::Tag
DESCRIPTION
MP3::Tag::File is designed to be called from the MP3::Tag module.
It offers possibilities to read/write data from files via read(), write(), truncate(), seek(), tell(), open(), close(); one can find the
filename via the filename() method.
parse_filename()
($title, $artist, $no, $album, $year) = $mp3->parse_filename($what, $filename);
parse_filename() tries to extract information about artist, title, track number, album and year from the filename. (For backward
compatibility it may be also called by deprecated name read_filename().)
This is likely to fail for a lot of filenames, especially the album will be often wrongly guessed, as the name of the parent directory
is taken as album name.
$what and $filename are optional. $what maybe title, track, artist, album or year. If $what is defined parse_filename() will return
only this element.
If $filename is defined this filename will be used and not the real filename which was set by MP3::Tag with "MP3::Tag->new($filename)".
Otherwise the actual filename is used (subject to configuration variable "decode_encoding_filename").
Following formats will be hopefully recognized:
- album name/artist name - song name.mp3
- album_name/artist_name-song_name.mp3
- album.name/artist.name_song.name.mp3
- album name/(artist name) song name.mp3
- album name/01. artist name - song name.mp3
- album name/artist name - 01 - song.name.mp3
If artist or title end in "(NUMBER)" with 4-digit NUMBER, it is considered the year.
title()
$title = $mp3->title($filename);
Returns the title, guessed from the filename. See also parse_filename(). (For backward compatibility, can be called by deprecated name
song().)
$filename is optional and will be used instead of the real filename if defined.
artist()
$artist = $mp3->artist($filename);
Returns the artist name, guessed from the filename. See also parse_filename()
$filename is optional and will be used instead of the real filename if defined.
track()
$track = $mp3->track($filename);
Returns the track number, guessed from the filename. See also parse_filename()
$filename is optional and will be used instead of the real filename if defined.
year()
$year = $mp3->year($filename);
Returns the year, guessed from the filename. See also parse_filename()
$filename is optional and will be used instead of the real filename if defined.
album()
$album = $mp3->album($filename);
Returns the album name, guessed from the filename. See also parse_filename() The album name is guessed from the parent directory, so it
is very likely to fail.
$filename is optional and will be used instead of the real filename if defined.
comment()
$comment = $mp3->comment($filename); # Always undef
genre()
$genre = $mp3->genre($filename); # Always undef
