hi Don

Code:
while read -r line
do
for i in $(cat test2)
do
if [ $line != $i ];
then
echo " The different value us $line"
fi
done
done < test1

i do not get the correct output. As per the my expectation i shud be getting all line from test1 except for the word "one". can you please help me correct the code. I am trying to extract lines from test1 that do not match lines in test2.

NAME
music123 - plays various sound files (usually including MP3, Ogg and Wav). SYNOPSIS
music123 [ -hqrvz ] file ... DESCRIPTION
music123 is a shell around various command line programs to play music files. It will descend directories trees with -r, and randomize file lists with -z. The programs used and the options given them are listed in /etc/music123rc or ~/.music123rc. OPTIONS
-h Show command help and exit; -q Quiet mode. No messages are displayed. -r Recurse into directories, instead of ignoring them. -v Display version information and exit. -z Play files in random order. -Z Play the files randomly and endlessly. -l Loop. -z -l differs from -Z in that -z -l will randomize, play through the song list (without repetition) in random order once, and repeat the songs in that order over and over; -Z will randomly play the songs, without any order, and will possibly play a song right after itself. -i Ignore extension case. -L List files and exit. -T Start a task that handle commands, only one command supported : quit, using q or Q will quit the application at the end of the cur- rent song. -D Set music123 not to delay between songs. (May make music123 harder to kill). -d Customize the time music123 delays between songs. -d takes one argument, expressed in seconds, which may have a fractional part. -@ Play the files listed in the mandatory argument of -@. Other files can be added on the command line, and this option can be given several times. Note that music123 doesn't yet play URLs. -- End option list. EXAMPLES
Play three songs: music123 test1.ogg test2.mp3 test3.wav Play a couple of directories and other songs at random: music123 -z -r Rock/ test1.ogg Pop/ test4.wav FILES
/etc/music123rc Describes which programs music123 uses, which files types it supports, and which options it passes those programs. ~/.music123rc Per-user config file to override the system wide settings. AUTHORS
