ANSI codes

[miriam_e]

For the past few years I've grown increasingly interested in using ANSI codes. They are codes that can make ordinary text do very interesting things, such as display in bold, italic, underlined, in color, or on a colored background. It can also do things like delete a word, or to the end of the line, or to the beginning of a line, or the entire line. It can move the cursor to a specific point on the screen, and many other things. Way back, decades ago, when I had my Amiga I used to play around with ANSI codes, but they have largely fallen out of fashion. As I say, in recent years my interest in them has renewed. Here is a file I refer to a lot, so much so, in fact, that I keep it on my desktop:

NOTE:  'ESC' is the escape character.

ESC[0m	  normal display (clear all F/X, use normal colors)
ESC[1m	  bold (bright colours in older rxvt)
ESC[2m	  dim or faint
ESC[3m	  italics (+ bright in some rxvt, not older ones)
ESC[4m	  underline
ESC[5m	  slow blink (or bright colours or bold)
ESC[6m	  rapid blink
ESC[7m	  reverse (swap background/foreground colors)
ESC[8m	  conceal (hidden)
ESC[9m	  strike through
ESC[21m	  double underline (or reset bold)
ESC[22m	  normal intensity (not bold, not faint)
ESC[23m	  not italic
ESC[24m	  not underline
ESC[25m	  not blinking
ESC[26m	  ???
ESC[27m	  not reversed
ESC[28m	  reveal (not concealed)
ESC[29m	  not strike through
ESC[3*m	  fg color (replace * with number below)
ESC[9*m	  fg bright color (replace * with number below)
ESC[4*m	  bg color (replace * with number below)
ESC[10*m	  bg bright color (replace * with number below)
	 *	color		bright color
	---	-----			------------
	 0	black		dark grey
	 1	red			bright red
	 2	green		bright green
	 3	orange		yellow
	 4	dark blue		bright blue
	 5	violet		bright violet
	 6	cyan		bright cyan
	 7	light grey		white

Commands can be combined: ESC[5;1;33;40m

Literal ESC character:
	shell scripts: echo -e "\e"
	sed  \x1b or \d27 or \o33 or \c[
	awk  \033 or \x1b
	rxvt or vi/vim/gvim  press CTRL-V then the ESC key. 

For more ANSI info study the output of 'infocmp' command.
