Spaces separate "words" in a command. And something that sometimes surprises people is that in shell scripts, brackets, that is, [ and [[ are both "commands". They take a series of arguments. For example, if [ "$?" -eq "0" ] ; then The "if" must be followed by a command to test its value. [ is a command, and takes four arguments: argument 1: $? argument 2: -eq argument 3: 0 argument 4: ] The "]" argument tells it to stop reading arguments. :) Using ; is equivalent to adding a newline, but prettier. It is legal to do this: if [ "$?" -eq "0" ];then It just looks really ugly. :) :) :) Spaces help you read. -- Eli Schwartz
