m3u-shuf

This supports a subset of the extended m3u format - requires the #EXTM3U header and keeps #EXTINF attached to each entry while shuffing.

CLI tool to shuffle a m3u file

Usage: m3u-shuf [OPTIONS] [FILE]

Arguments:
  [FILE]  m3u file to shuffle

Options:
  -o, --output <OUTPUT>  output file to write to
  -h, --help             Print help (see more with '--help')
  -V, --version          Print version

Install

Install cargo, then:

cargo install --git https://github.com/purarue/m3u-shuf

Example Usage

m3u-shuf playlist.m3u -o shuffled.m3u

If no output file is specified, it will write to STDOUT; can be piped to another command, or redirected to a file:

m3u-shuf playlist.m3u > shuffled.m3u

m3u-shuf | tee shuffled.m3u

Shuffling in place:

m3u-shuf playlist.m3u -o playlist.m3u

If no input file is specified, it will read from STDIN (e.g. with plainplay):

plainplay m3u rock | m3u-shuf | tee rock.m3u
