Due to some wierdness where my Bash only evaluates a variable as a single command (i.e. ignoring ';', '&&', & '||'), the following was necessary: test='eval exit 77 && dummy' This does the Right Thing (tm) in all the following cases: $test ($test) $test -args and -more args :; $test; dummy; more : && $test : || $test false || $test false && $test $test && : $test || : $test && false $test || false if $test; then :; fi I expect more parens aren't going to change anything.

tests & graceful tool dependencies
>From tests/defs: # User can set which tools from Autoconf to use. test -z "$AUTOCONF" && AUTOCONF=autoconf if ($AUTOCONF --version) >/dev/null 2>&1; then has_autoconf=: needs_autoconf=: else has_autoconf=false needs_autoconf='exit 77' fi What's preventing you from removing the needs_autoconf variable entirely and assigning something like AUTOCONF='exit 77 &&' in the case that autoconf is missing or broken? It removes a step and becomes transparent when a test doesn't want to test $has_autoconf.
