because you're testing "A==B" you need to give 3 parameters "A" "==" "B" $ cat x #!/bin/bash A="A" B="A" if [ $A != $B ]; then echo "not identical" fi if [ $A == $B ]; then echo "identical" fi if [ A!=B ]; then echo "not identical" fi if [ A==B ]; then echo "identical" fi Lee -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
