How do I look for specific options in a man page?


Say I want to lookup the compiler flag -Wall under the man page for the GNU fortran compiler gfortran.

I know that 'man gfortran' will get me the manual page for gfortran, but how do I lookup only the bit I want, which is '-Wall'? I can't find anything in the manual page for man.

I could use 'man gfortran | grep -Wall' but that would return just a single line and not the whole paragraph.

Thanks for any help

Search by pressing / then typing -Wall

'n' to move to the next match.

Just as a side note, on my system, I need to escape the dash to find a match. So, in the man page, I need to type:

/\-Wall

Not quite sure why that is. I never looked into it to find out.

If you normally have access to the web, http://linux.die.net/man/

This is actually a facility of the paginater program, not the man-page itself. Generally less in distros these days - "man less" will help greatly I would think.
