hi frank

i'm not a bash expert either: it took me 2 hours to come up with the following

enter the following 6 lines of code in a file called test

#!/bin/sh if [ $1 = $2 ]; then echo "ok" else echo "oops" fi

next, chmod 777 test then try it: ./test 1 1 and ./test 1 2

now go back and change the = to == and try it and you get

./test: [: ==: binary operator expected oops

With my bash, it always reacts correctly, regardless whether I call it as `bash' or `sh'.

note: bash is from slakware 3.5

Which version is this (try `bash --version')? Not that it's really important for GPC, but I always like to find out the reasons for problems.
