Re: sometimes i go huh (grep result)




What's tripping you up is that some processing is being done by the
shell before grep ever sees your pattern.  Taking that into account,
what grep is seeing is:

> me@ant(26)$ env | grep -F '-g'
grep -F -g
> grep: invalid option -- 'g'

> Try 'grep --help' for more information.
> me@ant(27)$ env | grep -F 'CFL'
> CFLAGS=-g
grep -F CFL
> me@ant(28)$ env | grep '\-g'
> CFLAGS=-g
grep \-g
(I'll note that in this case you need the quotes or the shell would have
stripped the \ .  I'm guessing this one is doing what you want)
