Bash Customizing PS1 Show previous command return status and time
Example
Sometimes we need a visual hint to indicate the return status of previous command. The following snippet make put it at the head of the PS1.
Note that the __stat() function should be called every time a new PS1 is generated, or else it would stick to the return status of last command of your .bashrc or .bash_profile.
# -ANSI-COLOR-CODES- #
Color_Off="\033[0m"
###-Regular-###
Red="\033[0;31m"
Green="\033[0;32m"
Yellow="\033[0;33m"

function __stat() {
if [ $? -eq 0 ]; then
echo -en "$Green ✔ $Color_Off "
else
echo -en "$Red ✘ $Color_Off "
fi
}
PS1='$(__stat)'
PS1+="[\t] "
PS1+="\e[0;33m\u@\h\e[0m:\e[1;34m\w\e[0m \n$ "
export PS1
