I would try

cat munna.c | grep -v disable_from_plugins > outputfile

This will output all lines except those matching the pattern disable_from_plugins, and direct it into outputfile.

You don't need the cat - give grep the filename, or redirect the file. These are pretty much equivalent:

grep -v disable_from_plugins munna.c >outfile
grep -v disable_from_plugins <munna.c >outfile

Or you could use sed and modify the source file directly:

sed -i /disable_from_plugins/d munna.c

i would not like to remove the line.
just wanna do some changes in the line..


for example "disable_from_plugins" , this is the word containing the line
search the line and change the line i.e
rame("rr.disable_from_plugins", 2);
to

If this is stuff you're going to be doing regularly, and the solution fits, you might want to use the c pre processor for this.
