The ANSI/VT100 terminals and terminal emulators are not just able to display black and white text; they can display colors and formatted texts thanks to escape sequences. Those sequences are composed of the Escape character (often represented by "^[" or "Esc") followed by some other characters: "Esc[FormatCodem".

In Bash, the character can be obtained with the following syntaxes:

The commands (for easy copy-paste):

echo -e "\e[1mbold\e[0m"
echo -e "\e[3mitalic\e[0m"
echo -e "\e[3m\e[1mbold italic\e[0m"
echo -e "\e[4munderline\e[0m"
echo -e "\e[9mstrikethrough\e[0m"
echo -e "\e[31mHello World\e[0m"
echo -e "\x1B[31mHello World\e[0m"
