tee question [OT]

[Marc Perkel]

Just wondering if any of you experts know how to do
this. I want to take an imput stream and produce two
output streams to feed into two different pipes.

echo "1 2 3 4 5" | tee ...
| cut -d \  -f -4 >> file1.txt
| cut -d \  -f 1,2,5- >> file2.txt

The idea being that file1.txt would get "1 2 3 4" and
file2.txt would get "1 2 5"

How do I do it? Tee wants a file as an argument and I
want that file to be a process. Anyhow - I'm not very
smart. 

Thanks in advance.

Everything can be a process, and in almost arbitrary order ... :-)

tee >(cut >file2.txt -d" " -f 1,2,5-) < <(tee >(cut >file1.txt -d" " -f -4) < <(echo "1 2 3 4 5")) >/dev/null
