@ Neo : Windows os only and im using Unix Shell/Bash scripting.
I have applied the below logic to eliminate comma if available in the string and then kept each string in array. Then I tried to search it in the file,but replacing the contents in the file is not working as expected.

For Scenario-1 :
Code:
#/bin/bash
STRING="user::r--,user:ourfrd:r--"
array=`echo $STRING | awk -F ',' '{ s = $1; for (i = 2; i <= NF; i++) s = s "\n"$i; print s; }'`
for word in ${array}
do
        sed -r -e 's/${array}[^{array}]+//g' file.txt
done

For Scenario-2 :
Code:
#/bin/bash
STRING="user::r--"
array=`echo $STRING | awk -F ',' '{ s = $1; for (i = 2; i <= NF; i++) s = s "\n"$i; print s; }'`
for word in ${array}
do
        sed -r -e 's/${array}[^{array}]+//g' file.txt
done

autorun

AUTORUN(1)																AUTORUN(1)

NAME

       autorun - automatically mounts/unmounts CDROMs and executes /path_to_cdrom/autorun after mounting

SYNOPSIS

       autorun [-lmqv?V] [-a EXEC] [-c CDPLAYER] [-e STRING] [-i MILLISEC] [-n STRING]
	       [-t STRING] [--autorun=EXEC] [--cdplayer=CDPLAYER] [--interval=MILLISEC]
	       [--lock] [--mountonly] [--notify=STRING] [--notify-insert=STRING] [--notify-eject=STRING]
	       [--quiet] [--verbose] [--help] [--usage] [--version] [cdromdevices...]

DESCRIPTION

       autorun	automagically  recognises  all	available CDROMs in your system, mounts them upon insertion and executes a possible 'autorun' exe-
       cutable on the CD. To allow an ordinary user to do this you have to add the options user,exec in /etc/fstab to the CDROMs you want to use.

       You may also use Autorun.desktop for KDE. Just place it in your Autostart folder.

       Command strings are parsed and %P% is replaced by the mountpoint path. %D% is replaced by the device path. After that  the  command  string
       will be executed using /bin/sh -c "command string";

OPTIONS

       -a, --autorun=EXEC
	      Execute  EXEC,  if the CD changes. This executable must be located on the CD. I.e. if you specify "--autorun=myprogram", and your CD
	      is mounted under /mnt/cdrom, after the CD is changed, autorun will attempt to run "/mnt/cdrom/myprogram". (default "/autorun")

       -c, --cdplayer=CDPLAYER
	      Run CDPLAYER, if an audio CD is inserted (default "/usr/bin/kscd")

       -i, --interval=MILLISEC
	      The time to wait in MILLISEC between checks (default 1000)

       -l, --lock
	      Lock the mounted media (unmount by hand)

       -m, --mountonly
	      mount/unmount only (do not execute anything)

       -n, --notify=STRING
	      Command STRING that will executed if the CD changes (default "/usr/bin/kfmclient configureDesktop")

       -t, --notify-insert=STRING
	      Command STRING that will executed if a CD was inserted and the autorun executable "/autorun" or the one specified with --autorun was
	      NOT executed. (default "/usr/bin/kfmclient openURL %P%")

       -e, --notify-eject=STRING
	      Command STRING that will executed if a CD was ejected (default "")

       -q, --quiet
	      Don't produce any output

       -v, --verbose
	      Produce verbose output

       -?, --help
	      Give this help list

       --usage
	      Give a short usage message

       -V, --version
	      Print program version

       Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
