All three share the core concept of various transformations applied to generated stream of file system entries, and consequently they also share the same set of global options. A quick way to check on that is to run:$ renamer -h
    $ tagger -h
    $ bmfp -hThat will show the global options along with specific commands for each tool. Getting more info on the commands level can be done using a similar approach, e.g. to learn more about therenamer replacecommand:$ renamer replace -hBy default the tools always visualize targeted changes (whenever possible) before actual processing.A little bit more details on each utility:Renameris a multi-platform batch rename tool. In addition to common operations such as regexp-based replace, adding text / dates, etc. it also supports advanced operations such as expandable template processing during replace, multi-level indexing across nested directories, flattening folders, and cleaning up non-media files.
At its simplest, Renamer can be used to print out the content of current directory:$ renamerWithout command arguments, renamer usesprintas the default command. This is also the case for both$ taggerand$ bmfp, with each of the tool showing info which is relevant to its intended purpose.
A little bit more advanced, to see what's lurking at the 7th nested folder level:$ renamer print -sl 7For multi-level indexing of all M4A files in all sub-directories of the current folder:$ renamer -r -in '*.m4a' index

    Proceed? [y/n]:Sequential indexing is supported as well using the-sqswitch.  An important detail here, by default Renamer is visualizing the targeted changes and asking for permission to proceed before actually doing anything.Taggermanages media metadata, such as tags and artwork. Setting those in selected media file over multiple nested directories now becomes a breeze, with just a few simple commands working uniformly over almost any practically imaginable audio / video media formats. While easy to use, Tagger supports advanced metadata manipulation such as regexp-based replace, expandable template processing, etc. For example, to set the title tag to respective file names followed by the values of track and tracktotal tags:$ tagger -r -in '*BWV816 1*' set --title '$filename, $track of $tracktotal'

    Proceed? [y/n]: nThe commands above show some of the available global options:-rfor recursion into nested folders and-into select media files. In the example above just one file was selected (for the sake of output brevity), which also could be achived via using-ffor the file source mode.BMFPis all about efficient media content processing, such as conversion between various formats, normalizing sound volume, segmenting / fragmenting media files, denoising audio, detaching individual audio / video streams, etc. As processing media files can typically be resource consuming, BMFP is designed to take advantage of multi-core processors. By default, it automatically breaks up jobs into individual tasks that are then run as separate processes on available CPU cores.BMFP is built on top ofFFmpeg, which needs to be installed and available in the command line. BMFP can be thought of as a batch FFmpeg runner, intended to make common uses of FFmpeg easy while not restricting its full power.For example, to convert all files from the above example from M4A to FLAC:$ bmfp -r convert -la -tf FLACThe-tfswitch specifies the target format, while-laexplicitly tells BMFP to do a lossless conversion.To check on the result, lets's just use thetagger'sability to print media files info:$ tagger -r -in '*BWV816 1*' print -st -ss
