# default PS1
#PS1='[\u@\h \W]\$ '

# depreciated
# 0: not bold, 91: bright red
# \e[m act like \e[0m, means reset so commands after it will not be colored 
# https://en.wikipedia.org/wiki/ANSI_escape_code#3-bit_and_4-bit
# need \[ and \] around color codes so bash ignore color codes when calculating line wraps?

#PS1='\[\e[0;91m\][\u@\h \W]\$ \[\e[0m\]'
# \033 can be used for dash printf, but \e can't? not sure why
#PS1='\[\033[0;91m\][\u@\h \W]\$ \[\033[0m\]'

# tput is better for different terminals? 
# but also need \[ and \] around color code for PS1! but seems no need for printf in script? why?
# setaf and sgr0 see `man terminfo`
PS1="\[$(tput setaf 1)\][\u@\h \W]\$ \[$(tput sgr0)\]"
