Hello

Im trying to use the 'grep' command.
when I type :

grep "hello" /library

I get a "grep undeclerd" error.

What am I doing wrong?

Do i have to include a certion header file?

Any help will be highly appreciated.

Thank you

Rotem

You aren't using a shell or your shell's PATH is not working correctly.
