Changing terminal colors

[infernosoft]

I've noticed that certain bash applications are customized in a way that let's certain things, like the 'username@hostname' part be in a different color.

How is this done?



P.S. I hope this makes sense

You can use escape codes, eg blue text on grey background:

echo -e "\033[47m\033[34m" "hello" "\033[0m"

The code sequences after the first two "\033" are for background and foreground respectively, use the table generated by this script (from a bash tutorial site I've forgotten) to choose:

#!/bin/bash

# prints a color table of 8bg * 8fg * 2 states (regular/bold)
echo
echo Table for 16-color terminal escape sequences.
echo Replace ESC with \\033 in bash.
echo
echo "Background | Foreground colors"
echo "---------------------------------------------------------------------"
for((bg=40;bg<=48;bg++)); do
	for((bold=0;bold<=1;bold++)) do
		echo -en "\033[0m"" ESC[${bg}m   | "
		for((fg=30;fg<=37;fg++)); do
			if [ $bold == "0" ]; then
				echo -en "\033[${bg}m\033[${fg}m [${fg}m  "
			else
				echo -en "\033[${bg}m\033[1;${fg}m [1;${fg}m"
			fi
		done
		echo -e "\033[0m"
	done
	echo "--------------------------------------------------------------------- "
done

echo
echo

I don't see any "Edit" option in my mrxvt terminal.

I think there is a misunderstanding as to what I'm asking. I wanted specific things colored in my terminal, like this (ie. the username is colored differently):

Does that make better sense? Sorry.

You do it this way:

PS1="\033[01;31m test \033[0m"

and put the username instead of "test". The PS1 environment variable is the primary prompt. There is also a
secondary and tertiary (PS2 and PS3) used for continuation lines of commands.

Check the man page on bash for some details. The first escape sequence sets the color, the second one resets.

Sweet. That works, now how can I set it so that it is like that when I open the terminal?
