Clearing some boxes recently, and pulled up an old gem that I used to carry around university. Mark Sobell’s Unix System V – A Practical Guide A lot of it is still relevant today for linux and even OSX users, with basic guides to shells, redirections, awk, sed and vi. Some of it is however (predictably) dated. Chapter 7 has some lovely spots to dig for buried treasure.
finger
Does my current machine even have finger? hehe, wow, it does.
karlp@teros:~$ finger Login Name Tty Idle Login Time Office Office Phone Host karlp Karl Palsson *:0 Sep 7 10:09 (:0) karlp Karl Palsson pts/0 23 Sep 7 10:09 (:0) karlp Karl Palsson pts/1 29 Sep 7 11:35 (:0) karlp Karl Palsson pts/2 Sep 7 11:35 (:0) karlp@teros:~$
Ok, cool, let’s try the example from the book!
karlp@teros:~$ finger quake@gldfs.cr.usgs.gov finger: unknown host: gldfs.cr.usgs.gov karlp@teros:~$
Oh well, somewhat predictable. No live earthquake list for me.
telnet services
We’ll skip over all the descriptions of FDDI, XNS, rlogin and hosts files, proceed straight to the library of congress information system.
karlp@teros:~$ telnet locis.loc.gov telnet: locis.loc.gov: Name or service not known locis.loc.gov: Unknown host karlp@teros:~$
Or not.
archie and gopher
wow, archie, I’d forgotten about archie and gopher. can’t even try these, no archie in current fedora, and no package for it either :)
Oh well. it was fun to skim over the chapter again :)
