Every now and then I get the following upon logging into a FreeBSD box:

Nice bash prompt: PS1='(\[$(tput md)\]\t <\w>\[$(tput me)\]) $(echo $?) \$ 

Seems like an odd choice for a tip, given bash is GNU and doesn’t come with the base system. I guess the maintainers figure sufficient numbers of sysadmins install bash from ports.

I try as much as possible to still use tcsh for my interactive shell, and standard sh for scripts.
