dump and restore (and their XFS equivalents for RHEL7) are still the 
only guaranteed ways to get a 100% accurate replica of a file system. 
Definitely worth keeping around.

Definitely not finger. It's a gaping security risk. Not so much chfn. 
The move to cross-platform federated identity services have made chfn 
far less relevant than it used to be. Likewise chsh.

Use netcat. It's a better tool for the kinds of things you might use 
telnet for other than logins. Use ssh for logins.

No. As with chfn, other identity services have supplanted YP/NIS.

I still occasionally use wall (write all) to notify users of impending 
shutdowns.

Yes, but I'm old fashioned this way. :)
