Function - play # uses mplayer random directories

I have this in my .bashrc and use it to play my music. It is organized by directories and this will play them in random order:

Code:

play(){ ## play directories with mplayer (random)
if [ $# -eq 0 ]
then
    # if no option show music types
    echo -n "
play {directory|style}

Styles:
-------"
    find  ~/music/ -maxdepth 1 -type d -print | cut -d'/' -f5|sort
else
    # create tmp list
    xtitle "mplayer tunes!"
    clear
    [ ! -e $1 ] && cd ~/music
    find -L $1 -type f -name \*.\* >play.$$
    if [ "$1" == "vids" ]
    then
        \mplayer -fs -msgcolor -shuffle -playlist play.$$ 2>/dev/null
    else
        \mplayer -msgcolor -shuffle -playlist play.$$ 2>/dev/null
    fi

    \rm play.* 2>/dev/null
    cd -
fi
}

I have many other tools and such, if folks find them of use I will post them.

rl(1) User Commands rl(1) NAME
rl - Randomize Lines. SYNOPSIS
rl [OPTION]... [FILE]... DESCRIPTION
rl reads lines from a input file or stdin, randomizes the lines and outputs a specified number of lines. It does this with only a single pass over the input while trying to use as little memory as possible. -c, --count=N Select the number of lines to be returned in the output. If this argument is omitted all the lines in the file will be returned in random order. If the input contains less lines than specified and the --reselect option below is not specified a warning is printed and all lines are returned in random order. -r, --reselect When using this option a single line may be selected multiple times. The default behaviour is that any input line will only be selected once. This option makes it possible to specify a --count option with more lines than the file actually holds. -o, --output=FILE Send randomized lines to FILE instead of stdout. -d, --delimiter=DELIM Use specified character as a "line" delimiter instead of the newline character. -0, --null Input lines are terminated by a null character. This option is useful to process the output of the GNU find -print0 option. -n, --line-number Output lines are numbered with the line number from the input file. -q, --quiet, --silent Be quiet about any errors or warnings. -h, --help Show short summary of options. -v, --version Show version of program. EXAMPLES
Some simple demonstrations of how rl can help you do everyday tasks. Play a random sound after 4 minutes (perfect for toast): sleep 240 ; play `find /sounds -name '*.au' -print | rl --count=1` Play the 15 most recent .mp3 files in random order. ls -c *.mp3 | head -n 15 | rl | xargs --delimiter=' ' play Roll a dice: seq 6 | rl --count 2 Roll a dice 1000 times and see which number comes up more often: seq 6 | rl --reselect --count 1000 | sort | uniq -c | sort -n Shuffle the words of a sentence: echo -n "The rain in Spain stays mainly in the plain." | rl --delimiter=' ';echo Find all movies and play them in random order. find . -name '*.avi' -print0 | rl -0 | xargs -n 1 -0 mplayer Because -0 is used filenames with spaces (even newlines and other unusual characters) in them work. BUGS
The program currently does not have very smart memory management. If you feed it huge files and expect it to fully randomize all lines it will completely read the file in memory. If you specify the --count option it will only use the memory required for storing the specified number of lines. Improvements on this area are on the TODO list. The program uses the rand() system random function. This function returns a number between 0 and RAND_MAX, which may not be very large on some systems. This will result in non-random results for files containing more lines than RAND_MAX. Note that if you specify multiple input files they are randomized per file. This is a different result from when you cat all the files and pipe the result into rl. COPYRIGHT
