Description:
With "set -u", invoking "which" results in the output of:
environment: line 1: _declare: unboundvariable
That should not happen, and does not happen, with prior versions
of bash.
I'm using Fedora 34 (beta).
Repeat-By:
Run this shell script:
#!/bin/bash
set -u
echo "$(which bash)"
`which' is not a bash builtin. It's probably a shell function that gets
loaded from one of your startup files.
