Dear John,
I want to believe that "termcap" is still supported somehow. While
confusing, I kinda liked it too.
Regards,
Flint

The terminfo "database", these days, is some kind of binary... and, from
the source file(s), there is a program to "compile" them into a structure
the curses library can just suck in as chunk and then use.
I kinda miss the old /etc/termcap ... yes, I've been around. Everything
balances out over time...

And, yeah, I recall the magtapes w/ line printer files which would
overprint to make pictures... ( RECFM=FBA LRECL=133 BLKSIZE=1330 )

Greetings,
Note that I missed a '"' in the last message. ...My bad.
When I did a "man term" I discovered that terminal types were kept in
alphabetical order under the directory "/lib/terminfo". On my distro of
Linux, A painless way to list them is the following:
find /lib/terminfo/. |cut -d "/" -f 6 |grep . |less && wc -l
Which lets you look at them and tells you how many there are.
My first attempt, which is also valid is as follows:
sudo apt-get install tree or yum install tree
Then this bit of flummery:
tree /lib/terminfo | cut -c 14- |strings
Either of these will give you a list of terminal types available on your
system.
My Linux Mint appears to have 41 choices.
To pick one for use try:
echo $TERM # note where you start.
export TERM=ansi # you can pick one of the terminal types
# both "dumb" and "linux" are viable
echo $TERM # see the new type.
Enjoy.

Greetings John Campbell and Dell Harris,
I find that the output from the excellent line of bash provided below by
Big John great entertainment. But before we disappear into troff (or
sphinx :^), could I suggest a different approach if you are "man" enough...
Try this:
man term
Much information will come your way, and I look forward to further
discussion of this issue.
My favorite resolution of this has always been to type in:
echo $TERM
I always the same answer...
xterm
Finally, the bash line supplied by John will only work with "root
privilege. For now I would advise staying away from root, particularly
on production systems... I would be happy to consult on this topic some
more at your convenience and pleasure.
Sincerely,
Flint

Well...
Perhaps pawing through /etc/profile _might_ be edifying.
You can cheat by:
cd /etc
find . -type f -print | while read F ; do grep TERM "${F}" && echo
"${F}" ;
done
to find out where this can be getting set. It might even be somewhere
under /etc/defaults but don't quote me on that.
Mind you, I don't currently have access to BFI (Big Fast Iron, either a
zSeries or an S/390) at this point so YMMV.
A long, long time ago when there were many, many deviants of Unix, I
tended
to paw through various /etc and /usr/include files to pick up tricks.
Man
pages gave some hints but the actual _structures_ you need for ioctl()
and
fcntl() calls were a bit more entertaining :-) ...

Hi,
I'm trying to figure out why TERM is being set to linux instead of dumb
on
the GRUB_CMDLINE_LINUX_DEFAULT in the /etc/default/grub line of a
system-z
guest on install of SLES 12 SP2. TERM=dumb is set in the parmfile but
after the install it's set to linux. Does anyone know of a way to get
it
to set TERM=dumb on install?
Thanks
Dell Harris
