I am about to write a shell script. I would like to be able to visually distinguish some of its output text as a warning, by setting its color to yellow.
How is this done?
From "Shell colors: colorizing shell scripts":
echo -e "\033[33mThis is yellow\033[0m"
echo -e "\e[33mThis is yellow\e[0m"
\033 or \e as an Escape character starts the escape sequence, which in this case contains the controls to change colors.
