title: tput: unknown terminal
body: <p>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:</p>
  
  <pre><code># tput
  unknown terminal "xterm"
  # echo $TERM
  xterm
  # tput -T ansi
  unknown terminal "ansi"
  </code></pre>
  
  <p>In fact, ...</p>
  
  <pre><code># ls /usr/lib/terminfo/x
