I recently backported some bash scripts developed on cygwin to linux.
to my surprise I got an interpretation error on a few of them. here's a
if [ "$1" == "" ]; then
while [ -z "$INSTALL_DOMAIN" ] ; do
echo -n "Enter server web domain name: " ;
read INSTALL_DOMAIN ;
this works on cygwin bash (latest fix) but gives:
t.sh: [: ==: binary operator expected
my Oreilly 'Learning the bash shell' book says that using == is a
common beginner mistake. I was wondering about this.....
