exfalso
exfalso(1) General Commands Manual exfalso(1) NAME
exfalso - audio tag editor SYNOPSIS
exfalso [ directory ] DESCRIPTION
Ex Falso displays and edits audio metadata tags. Supported formats include MP3, Ogg Vorbis, FLAC, Musepack (MPC), WavPack, and MOD/XM/IT. This manual page is only a short reference for Ex Falso. Complete documentation is available at http://code.google.com/p/quodli- bet/wiki/Guide. OPTIONS
Ex Falso may be given a directory to open on the command line. TIED TAGS
Many places in Ex Falso allow you to use "tied tags". Tied tags are two tag names joined together with a "~" like "title~version" or "album~part". Tied tags result in "nice" displays even when one of the tags is missing; for example, "title~version" will result in Title - Version when a version tag is present, but only Title when one isn't. You can tie any number of tags together. RENAMING FILES
Ex Falso allows you to rename files based on their tags. In some cases you may wish to alter the filename depending on whether some tags are present or missing, in addition to their values. A common pattern might be <tracknumber>. <title~version> You can use a '|' to only text when a tag is present: <tracknumber|<tracknumber>. ><title~version> You can also specify literal text to use if the tag is missing by adding another '|': <album|<album>|No Album> - <title> See http://code.google.com/p/quodlibet/wiki/Guide_Renaming. BUGS
See http://code.google.com/p/quodlibet/issues/list for a list of all currently open bugs and feature requests. AUTHORS
