Environments belong to *processes*, and a process cannot change the environment of another process, with one exception: when a new process is created with fork(), the child process is initialized with a copy of the environment of its parent. Typically you accomplish this kind of thing by setting the variable in some kind of shell initialization script like .profile which is read by your shell when it starts. Then when you start any program from your shell, that program will pick up the setting, since it's a child of the shell. That still doesn't take care of processes that aren't started by your shell (web servers, etc.). Those programs will have their own way of initializing their environment (e.g. Apache's httpd.conf file). -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
