Thanks Sina,
In your first post you said:
ls --help | wc -l
Wouldn't it only count the number of lines within the help file of the ls
command?
The grep is a much better idea, I tried something like:
ls --help | grep -c '-'
and it returned 51 because it counted both '-' and '--', but don't know how
to ... is there a logical or operator for situations like this?
I want to check for '-' or '--'
How to do that?
Many thanks!
Ned
