[Help-bash] How to get all the return status in an assignment statement?

[Peng Yu]

Hi,

The following code shows that I can only get the return status of the
last $(). Is there a way to get all the return status like the way
with PIPESTATUS?

#!/usr/bin/env bash

x=$(echo x; exit 1) || echo $?
echo "^$x\$"

x=$(echo x; exit 1)/$(echo y z; exit 2) || echo $?
echo "^$x\$"

x=$(echo x; exit 1)/$(echo y z) || echo $?
echo "^$x\$"
