Folks:

I need to do the following stuff:

Find the particular string in a file and remove that line which has that particular string from the file , that should be done from the command line or from the script.

Thanx... Britto

Read all about it:

	man sed

In particular:

	sed -e'/REGEX_PATTERN/d' < input_file > output_file

Note that input_file and output_file need to be different.

Regards,

Kapil. --

Sounds like a homework question and we don't do people's homework for them.

I will give you a hint. Read the man page for grep.
