With a bit of precaution, this should work:

foo-status=$(mktemp -t)
(foo; echo $? >foo>$foo-status) | bar
foo_status=$(cat foo$foo-status)

With a bit of precaution, this should work:

(foo; echo $? >foo-status) | bar
foo_status=$(cat foo-status)

With a bit of precaution, this should work:

foo-status=$(mktemp -t)
(foo; echo $? >$foo-status) | bar
foo_status=$(cat $foo-status)
