Given this file called playlist.txt:

"/music/Country/Rascal Flatts/Rascal Flatts/It's Not Just Me.mp3"
"/music/Rock/AC-DC/Back In Black/AC-DC - 09 - Shake A Leg.mp3"

If I cat the file in a meta command, it breaks up each line on the spaces
(See below) How can I ensure the entire line is passed to an application
like mplayer?


for i in $(cat playlist.txt); do echo "$i"; done
"/music/Country/Rascal
Flatts/Rascal
Flatts/It's
Not
Just
Me.mp3"
"/music/Rock/AC-DC/Back
In
Black/AC-DC
-

Shake

Try this:

while IFS= read -r i
do
printf "%s\n" "$i"
done < playlist.txt

[...]

That file happens to be in a format recognised by xargs, so
that's only:

xargs echo < playlist.txt

See man xargs for more options.

See man mplayer. You can use a playlist file on the command line.
(Not sure if it requires a special file format, but that's easy to find
out.)

You don't specify which shell you're using, but in bash, it's possible to
specify a "read" command without any variable, in which case the entire
line is read and stored in the default $REPLY variable.

For example:

while read
do
mplayer "$REPLY"
done < playlist.txt

Caveat: anytime you find yourself using "cat", try thinking again about
an alternative way to accomplish what you're trying to do. UUOC (Useless
Use Of Cat) awards abound in Usenet.
