Another thing that may help you, if it’s absolutely needed:
Before we had ${PIPESTATUS[*]} I wrote things like this:
foo | (bar; echo $? >bar.rv) | baz
Similarily, you can do tricks with high file descriptors.
x=$( (echo foo | (tr a-z A-Z >&4) | (echo bla >&5)) 4>&1) 5>&1
echo x=$x
This gives:
bla
x=FOO
Both not as efficient as direct variable assignment, but…
And let's not forget using…
while …; do …; done <foo
… instead of…
cat foo | while …; do …; done
… (which is cat abuse anyway).
Often, some not-so-basic or more modern scripting approaches
can eliminate the need for a construct like you were asking for.
Good luck,
