#PROMPT_COMMAND='date +%T'
# with trap prints time twice.
#PROMPT_COMMAND='trap "date +%T" DEBUG'
# Regarding tracking execution time,
#  then github.com/paypal/gnomon is a handy tool.
# Without adding anything external, prepending `time` to a command 
#  prints out execution time.
# OR switch to ZSH which has $bash_preexec and other nifty features.

# TODO: 
#  * add an alias that extracts ip address from `ip a`
#  * Select distinct color-scheme for user and root prompt
#  X add install script for necessary applications
#    x snap [or flatpak or better] for slack
#    x neofetch
#  x show time after command has been entered. Either with PROMPT_COMMAND or bash-preexec

#  * bash 4.4.12 on Debian 9.9 stretch doesn't really like \e as an escape character
