I parsed the grammer the other way. The messages are the almost same when the command you are looking for, mozilla in this case, is not found. > And they're builtin commands if 'bash' is your shell (and maybe others). Hopefully lots of others. Those are defined by standards such as SUSv3. I expect every standard shell to have them. And by standard that does leave out csh. ;-) But any shell that claims to be a POSIX shell that could function as /bin/sh on a modern system should be good to go for those. Bob
