A tool to maintain and operate on playlists.

• Check if all songs are existing
• Manages playlists if songs have to be moved within the music folder tree
• Shuffle playlist order. Interprets are considerd during shuffling so they don't follow each other
• Sort a playlist (case insensitive)
• Combine playlists to one list
• Remove content of one playlist from others
• Extract common entries of two playlists
• Convert playlists

Currently only m3u and m3u8 playlist formats are supported. Both without comment extensions.

Usage: songBase [<options>] [<list> ...]

<list> Path to a playlist or '-' if playlist should be read from standard input. '-' can only be specified once. Otherwise some operations allow to specify more than one playlist.

Currently only m3u (ISO8859-1) and m3u8 (UTF-8) playlist types are supported.

--base <dir>
Base folder for searching playlists. If playlists <list> are specified it defaults to the folder of the first playlist. If '-' is specified it defaults to the current working directory.

--out <file> If a playlist has been modified the changes are written to the specified file. If '-' is specified for <file> the playlist is written to standard output. If option '--out' is used only one playlist argument can be specified.

--dryrun
No changes are made. Only report what would be done.

--nocheck
Don't check if a songs exists when reading in the playlists

--nointerpret
During default map operation: don't check for interpret folders

--rmsource
During map operation: delete a song in the source folder if it already exists in destination folder

--sorted
All playlists which has to be written are sorted before writing them. This also applies to standard output writes. Case is ignored during sorting.

--type <type>
Playlist type when reading from standard input and writing to standard output (defaults to m3u)

If no operation is specified but the '--out' option with one playlist argument the playlist format can be converted. --map <a>=<b>
Move all songs from folder <a> found in playlist <list> to folder <b>. Only one playlist argument is allowed. All other playlists found in the base folder are updated to reflect this move. A special behavior in this operation (if not switched of with option '--nointerpret') is that if there is a folder with the name of the interpret then the song is moved to this folder instead of <b>.

--check
Only check all playlists found in the base folder (defaults to working directory) if their songs exist.

--sort
Sorts all playlists supplied as arguments. If solely '-' is specified standard input is sorted and written to standard output. If option '--out <file>' is specified the output is written to the specified file.

--shuffle [<gap>]
Shuffles all playlists supplied as arguments. If solely '-' standard input is shuffled and written to standard output. If option '--out <file>' is specified the output is written to the specified file. <gap> is an optional number of songs which should be between songs of same interpret (default: 5). Please note that the gap also depends on the variety of interprets and may be lower than requested.

--select <text>
Write entries of playlist <list> which contains text <text> to standard output. Multiple playlist arguments are allowed. The text is searched in the folder, interpret and title part. The search is case sensitive.

--add <list2>
Add content of playlist <list2> to all playlists supplied as arguments. If solely '-' is specified the union of standard input and <list2> are written to standard output. If option '--out <file>' is specified the output is written to the specified file. If no playlist is supplied as argument the songs from <list2> are added to all playlists found in the base folder.

--remove <list2>
Remove content of playlist <list2> from all playlists supplied as arguments. If solely '-' is specified the differences between standard input and <list2> are written to standard output. If option '--out <file>' is specified the output is written to the specified file. If no playlist is supplied as argument the songs from <list2> are removed from all playlists found in the base folder.

--union
Write content of all playlists supplied as argument to standard output.

--intersect <list2>
