Byobu provides a special PS0 and PS1 prompt command, compatible with Bash shells. It will display the
previous command's total runtime and exit code, if it's not zero. It will use 3 separate colors for the
local username, hostname, and the current working directory.
byobu-enable-prompt will add one line to your ~/.bashrc.
You can safely remove the line from your ~/.bashrc, which ends in #byobu-prompt.
byobu-disable-prompt will remove its color configuration from ~/.bashrc.
byobu-prompt is an interactive wrapper of the previous two tools.
