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

       48
# 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.
