Unix: Useful and pretty prompt
Some servers at work has varying degrees of useful prompts when I connect to them through SSH. Usually they are quite annoying and for example showing the shell type and version, which I frankly don't care much about. Here's how to make it show the current user, hostname and working directory. In addition the hostname is made more visible, which is a nice effect.
$ bold=$(tput bold) $ reset=$(tput sgr0) $ export PS1="\u@\[$bold\]\h\[$reset\]:\w\$ "
Stick it in your
.bash_profile or whatever else you've got going on to make it more permanent.
