Shell Colors

Printing Colored Text

When printing colored text, make sure you end messages with the ‘reset’ escape sequence to stop the color from continuing past the message and affecting future messages.

color_msg() {
    local color="$1"
    local msg="$2"
    printf "%b%s%b\n" "$color" "$msg" "$RESET"
}

You can also use echo to print colors, but you need to use the -e flag to set the command to escape backslashes.

color_msg() {
    local color="$1"
    local msg="$2"
    echo -e "${color}${msg}${RESET}"
}
