|
|
><P
|
|
>Dan was a coworker of mine at the university I work at for a while. Dan
|
|
used csh and tcsh for a long time before moving to Bash, so he uses the
|
|
history number a lot. He uses "screen" a lot, and for that, it's helpful to
|
|
have the tty. The last part of his prompt is the return value of the last
|
|
executed command. Dan doesn't like having the $PWD in his prompt because it
|
|
makes the prompt grow and shrink too much. </P
