Expected results: In step 2, the output is 1 (false in shell semantics). Sorry for the typo.. (In reply to comment #0) > 2. test -n $VAR ; echo $? You need to write: test -n "$VAR" ... so that "test" actually gets an empty string. Otherwise shell will throw the empty string away. Additionally, you are probably using the shell built-in command "test", not the executable /usr/bin/test from coreutils: http://www.gnu.org/software/coreutils/faq/coreutils-faq.html#I-am-having-a-problem-with-kill-nice-pwd-sleep-or-test_002e |
