Here's an annoying issue that I've run into a few times while using the terminal (or iTerm) on OSX Lion.
tput: unknown terminal "xterm-256color"
No entry for terminal type "xterm-256color";
using dumb terminal settings.
The issue derives from OSX Lion's terminal color settings, which is not always compatible with the settings on remote servers. There are a few ways to fix this issue.
- manually set:
$ export TERM=xterm-256
- override $TERM in ~/.profile on remote server:
[ "$TERM" = "xterm" ] && TERM="xterm-256color" alias ls='ls --color'
- change the emulation type for terminal from xterm-color256 to xterm-color, in preferences->advanced
