Hello -

I am not sure if this is what you mean, but go to your search engine of choice and search on "UNIX Rosetta Stone" and you will find things like this:

Rosetta Stone for Unix

This will show you lots of the programs on various *nix systems organized by tasks.

Ummm - I meant to also mention a useful command on many flavours of *nix

apropos

If you are on a system and are wondering about (for example) partitioning utilities, type:

"apropos partition"

(sans quotes)

and you will see a list of commands that have the keyword 'partition' in their man pages. This will lead you to the man pages and the info pages that can get the in depth info you need.

Michael

thanx for your help
