This is fine.. but i want it generalised. I mean i should be able to give input text to it..

---------- Post updated at 05:10 AM ---------- Previous update was at 05:08 AM ----------

Code:
#sed -n '/efgh/,/%/{s/efgh-- //;s/%//;p;}' sample.txt

This gives the desired output for that 'efgh'
But does not give correct output for 'abcd'..
pls suggest

Code:
sed -n '/abcd/,/%/{s/efgh-- //;s/%//;p;}' sample.txt
abcd -- this is the first line
this is the
second line and not
able to print

SYNOPSIS

       head [OPTION]... [FILE]...

       -n, --lines=NUMBER
	      print first NUMBER lines instead of first 10

       -q, --quiet, --silent
	      never print headers giving file names

       -v, --verbose
	      always print headers giving file names

       --help display this help and exit

       --version
	      output version information and exit

       SIZE may have a multiplier suffix: b for 512, k for 1K, m for 1 Meg.
