read a string from its end to its start and stop when you find a specific character
How can I do this? Actually I have a file which contains a path
e.g.
/home/john/Music/hello.mp3
and I want to take only the filename (hello.mp3) So, I need to read the file from its end to its start till the character "/"
Is this possible?
Thanks, I am sure you'll not disappoint me here!
Oh, yes, you are the best!

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
