It took a bunch of searching a testing, but I got something that works for me and I like well. Instead of every screen window being called “bash” or being named manually, I now have them all named after the working directory. This is the magic:<\/p>\n

PROMPT_COMMAND='echo -ne \"\\033k$(basename $PWD)\\033\\\\\"'<\/code><\/p>\n

PROMPT_COMMAND<\/tt> gets run every time bash displays a prompt, and those particular escape characters do the magic.<\/p>\n

To avoid crap outside of screen, I did this:<\/p>\n
