Again, thank you very much - I'm quite blown away at how supportive this community is; very motivating. I will have to see what a "bash tutorial" search turns up because beyond "ls" & "cd" I don't know all that much (& those man pages can be something horrible to decipher!). I'll have to find a way to incorporate this exploration with my studies, because there is not all that much spare time for learning 'on the side' as it were (!). Warm regards to you all & my sincere thanks. - Abel --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "mnemosyne-proj-users" group.
