para_afh - print or modify meta information about audio file(s)SYNOPSIS
para_afh [--help] [--detailed-help] [--version] [--loglevel=<severity>] [--chunk-table] [--parser-friendly] [--modify] [--backup] [--preserve] [--year=<string>] [--title=<string>] [--artist=<string>] [--album=<string>] [--comment=<string>] [--] file...DESCRIPTION
By default para_afh prints information about the given audio files, such as format, duration, bitrate, etc., and the content of the most common meta tags (artist, title, album, year, comment). In modify mode it changes the meta tags to the values given at the command line.OPTIONS
The following options are implemented generically and are available for many of the commands.
print help and exit
print help, including all details, and exit
print version and exit
control amount of logging
values: debug, info, notice, warning, error, crit, emerg
Log only messages with severity greater or equal than the given value. Possible values:
debug: Produces really noisy output. info: Still noisy, but won’t fill up the disk quickly. notice: Indicates normal, but significant event. warning: Unexpected events that can be handled. error: Unhandled error condition. crit: System might be unreliable. emerg: Last message before exit.
print also the chunk table
The chunk table of an audio file is an array of offsets where each offset corresponds to chunk of encoded data. The exact meaning of chunk depends on the audio format.
Programs which are unaware of the particular audio format can read the chunk table to obtain the timing information needed to stream the file.
do not use human-readable output format
This option only affects the format of the chunk table, so it has no effect if --chunk-table is not given.
The human-readable output (the default) consists of one output line per chunk and the output contains also the chunk number, the duration and the size of each chunk. The parser-friendly output prints only the offsets, in one line.
modify (rather than print) tags
If this option is given, para_afh creates a temporary copy of the given file(s), with meta tags changed according to the options below. On errors, the temporary file is removed, leaving the original file unchanged. On success, if --backup is given, the original file is moved away. Finally the temporary file is renamed to the name of the original file.
create backup of the original file
The backup suffix is ’~’. That is, a single tilde character is appended to the given file name.
preserve modification time
If this option is given, the mtime of the modified file is set to the value prior to the modification.
set the year tag
set the title tag
set the artist tag
set the album tag
set the comment tagCOPYRIGHT
