Bash Version: 3.0 Patch Level: 16 Release Status: release Description: POSIX XCU 2.9.1 requires that for all simple commands (special built-ins or otherwise), variables be set in the current environment BEFORE executing the command. Therefore, both of the two special built-ins that can unset variables (unset and .) should end up with foo not set in the environment after completion, but with bar remaining set. The trace shows that unset is buggy. See my report to the austin group, https://www.opengroup.org/sophocles/show_mail.tpl?source=L&listname=austin-group-l&id=8356 Repeat-By: $ set -o posix $ echo unset foo > dot $ unset foo bar $ foo=bar bar=blah unset foo # BUG - foo should be unset $ echo ${foo-unset} ${bar-unset} bar blah $ unset foo bar $ foo=bar bar=blah . ./dot # Correct - only bar remains set $ echo ${foo-unset} ${bar-unset} unset blah $ - -- Life is short - so eat dessert first!
