Hi All,

I know how to read things on the command line.  But
how to other's figure out what goes together when things
don't arrive in order?

For instance, from "man grep"

 -E, --extended-regexp
              Interpret PATTERN as ...

 -F, --fixed-strings
              Interpret PATTERN as ...

The -E and the -F can be in any order on the command line

Is there some module that you can send the run string
to with  "-E" (or similar) and it gives you back
what comes directly after "-E"?

I could do this manually, but it seems to be a lot of work.

How do they do that?

Many thanks,
