Ok, thanks again, to you and Curt!

I see the difference, but it may take a little while for it to really soak in 
(and / or to recognize a use / need for it (for me)), but I guess I learned 
something ;-)

It sort of looks like that, with the -l option, if there were additonal files 
that also had matches, I might have to restart the command to find others, but, 
I'm not sure of that, and I guess I'd have to run a more extensive  test to 
confirm that, like creating at least two files with matches and put them in a 
directory (probably with some other files that don't match).

I'm not ready to do that at the moment, so I'll leave it there for now.

(And, I doubt there's a way to run the same command using standard input twice 
(e.g., something like grep test - - ...).)

For anyone else who is interested, my tests are shown below:

<quote>
rhk@s19:/rhk/ked1$ grep test - >| /tmp/a ; echo "and the output is" ; cat 
/tmp/a
one
two
test
one
two
test
^C
rhk@s19:/rhk/ked1$ less  /tmp/a
rhk@s19:/rhk/ked1$ grep -l test - >| /tmp/a ; echo "and the output is" ; cat 
/tmp/a
one
two
test
and the output is
(standard input)
rhk@s19:/rhk/ked1$ grep -L test - >| /tmp/a ; echo "and the output is" ; cat 
/tmp/a
one
two
test
and the output is
rhk@s19:/rhk/ked1$
