Mike,
thanks again, and it surely works. Would you explain a little bit of what you have done?
cat <<EOF | mailx -s "subject" target@address
is it like, you cat whatever in the new file EOF which contains the "mailx -s ..... " does the | works just like the regular | does? thanks

Hey, no problem, glad I could help out
The syntax of this is a little confusing, even to me if I just give it a quick glance. But so many things with Linux/Unix are until you get used to them
Basically, I'm catting everything up to the EOF delimiter (which could have been called anything like END or something) and piping all that to mailx, like a regular pipe (|)
The confusing part is the input/output on the same line:
It's equivalent to sending output to a file, which looks like it makes more sense, even though it's the exact same principle
except instead of dumping the output from after the cat command up to EOF into a file, we're piping it to mailx.
Does that make sense? When you've done it enough times it seems harder to explain it
Best wishes,
Mike
