Fedora 20 using dash 0.5.7 works: $ dash -c 'unset "a|b"' dash: 1: unset: a|b: bad variable name $ rpm -q dash dash-0.5.7-8.fc20.x86_64 But RHEL 6 fails: $ dash -c 'unset "a|b"' $ rpm -q dash dash-0.5.5.1-4.el6.x86_64 so this is at least one bug that has already been fixed upstream. >> $ env 'a|b=' dash -c 'set | grep a"."b' >> a|b='' > > This I can reproduce though. Meanwhile, I just tested the latest dash.git (commit f21016a12) and this behavior is no longer present: $ env 'a|b=' ./src/dash -c 'set | grep a"."b' so it has also been fixed in the meantime.
