The greatest benefit of Unix to me has been its pervasiveness, it has made it possible for me to move between organisations without having to learn another operating system before I can work on the databases.

This is mainly about the shell - because that's what I use to do everything outside the database.  I have avoided using 'C' type shells, so this is about Bourne style shells, Korn, Z and of course bash.


My favourite feature is 'disown'.  This allows you to start a huge database export at lunch time, realise you should have run it in a 'nohup' hours later and to disown it instead, so that when you log out it doesn't get terminated.

There will be more about shell matters later!
