tput: unknown terminal

Question

I'm on AIX-6.1 and I'm trying to make use of tput inside my $PS1. I've confirmed I can't even run tput from the commandline. Following is my session:

# tput
unknown terminal "xterm"
# echo $TERM
xterm
# tput -T ansi
unknown terminal "ansi"

In fact, ...

# ls /usr/lib/terminfo/x
x1700  xl83        xterm+pcc3  xterm+pcfkeys   xterm-88color  xterm-hp     xterm-old  xterm-vi

# ls /usr/lib/terminfo/x | wc -l

# for term in $(ls /usr/lib/terminfo/x) ; do tput -T $term ; done 2>&1 | grep 'unknown terminal' | wc -l
      48
# for term in $(ls /usr/lib/terminfo/x) ; do TERM=$term tput ; done 2>&1 | grep 'unknown terminal' | wc -l
  48

Any ideas? Thanks in advance.

Answer 1

Is your TERMINFO variable set? Without it, I believe the system won't find your terminfo files. Or perhaps it is set incorrectly?

If you're running sh, ksh, bash or similar, try:

export TERMINFO=/usr/lib/terminfo

If you're not sure what shell you're using (I'm pretty sure you do, but others might read this too), type:

echo $SHELL

If you're using csh, tcsh or similar, then you should instead type:

setenv TERMINFO /usr/lib/terminfo

After that, try running tput again.

Thank you for this answer, Enfors! I was having a problem with Drush on Ubuntu 12.04 throwing me a "tput: unknown terminal..." error each time I executed a Drush command. Your advice fixed my problem. Thanks!! – Wedged

I had this issue under MSYS2 on Windows (x86_64). It was working, then I installed gcc and a few tools and it started failing. Anyway, adding a conditional export of TERMINFO fixed it. Thanks! – Emigrate

Answer 2

I fixed this in Mac OS Catalina with,

export TERMINFO=/usr/share/terminfo
