Hi rdrtx1, It works perfectly. Many thanks for your support.
Hello,
Can you explain why in the first 2 commands the awk does not print anything? Is it looking of a specific format ?
Thanks.

$ echo a123 | awk '($1>=2) {print $1}'

MPD-DYNAMIC(1p) User Contributed Perl Documentation MPD-DYNAMIC(1p)NAME
mpd-dynamic - a dynamic playlist for mpd
VERSION
version 1.120610
DESCRIPTION
This program implements a dynamic playlist for MPD, build on top of the Audio::MPD perl module.
MPD (music player daemon) is a cool music player, but it lacks a dynamic playlist. A dynamic playlist is a playlist that will change
automatically over time. In particular, it will remove already played songs (keeping at most a given number of songs) and add new songs to
the playlist so it never fall short of songs.
Note that since mpd is a daemon needing no gui to work, "mpd-dynamic" is also a daemon. That is, it will fork and do all its work from the
background. This way, you can fire "mpd" and "mpd-dynamic" and forget completely about your music (especially since "mpd-dynamic" is a
low-resource program): it will just be there! :-)
USAGE
mpd-dynamic [options]
OPTIONS
General behaviour
You can customize the usage of mpd-dynamic with the following options:
-o[ld] <old>
Number of old tracks to keep in the backlog. Defaults to 10.
-n[ew] <new>
Number of new tracks to keep in the to-be-played playlist. Defaults to 10.
-s[leep] <sleep>
Time spent sleeping (in seconds) before checking if playlist should be updated. Default to 5 seconds.
-d[ebug]
Run mpd-dynamic in debug mode. In particular, the program will not daemonize itself. Default to false.
-e[ncoding] <encoding>
Print debug messages with this encoding. Since mpd-dynamic is meant to be a silent daemon, this option will not be used outside of
debug mode. Default to "utf-8".
--version
--usage
--help
--man
Print the usual program information
Note however that those flags are optional: since "mpd-dynamic" comes with some sane defaults, you can fire "mpd-dynamic" as is.
Ratings
You can also take advantage of ratings if you want. With those options, songs need to have at least a given rating (or no rating yet) to be
inserted: this way, you will only listen to your favorite songs!
Ratings can be created / updated with "mpd-rate".
Note that if you supply a non-existant rating db-file, the rating mechanism will be ignored. The following options control the rating
mechanism:
-r[atings] <ratings>
The path of a db file with the ratings per song. The keys are the song path (relative to MPD root), and the value is an integer (the
rating). Default to "~/.mpd/ratings.db".
-m[in[imum]] <min>
The minimum rating for a song to be inserted in the playlist. Default to 4.
