Dan's Prompt
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 $PWD in his prompt because it makes the prompt grow and shrink too much. I address this somewhat in the twtty prompt.
Code:
#!/bin/bash # Dan's prompt looks like this: # 543,p3,0$ # PROMPT_COMMAND="" function dan { local cur_tty=$(tty | sed -e "s/.*tty\(.*\)/\1/") PS1="\!,$cur_tty,\$?\$ " }
