The environment is only exported to programs started by the one that exported it - that is, you can't affect your parent process. Normally, commands are executed in subshells that exit when finished. For the cases where you want to execute commands in your current shell, you must 'source' the file containing them. You can abbreviate the source command as '.', but probably want you really want is to put the commands in the files that are always sourced by your login shell which would be .profile for yourself or /etc/profile for everyone. There are also shell-specific variations of this, like .bash_profile and ones that are also source by subshells (so they can contain functions) like .bashrc. -- Les Mikesell lesmikesell@xxxxxxxxx If you want to execute commands in your current shell
