>Description:
The man page for the command grep has a typo/error in it.

The option syntax for "line-buffered" output is specified in the man page as:

--line-buffering

Whereas the command itself takes (from grep --help, and checked by running)

      --line-buffered       flush output on every line      
>How-To-Repeat:
Check "man grep" and "grep --help", also trying passing both to grep to verify.
>Fix:
Update man page to reflect actual syntax with " --line-buffered"
