Printf "Greyscale 232 to 255 for 256 colors\n" Printf "Colors 0 to 15 for the standard 16 colors\n"įor ((c = 0 c 5 & (i = 0, ++j))) & printf " |" The \ symbols allow bash to understand which parts of the prompt cause no cursor movement without them, lines will wrap incorrectly.Īnd here is a function to pick colors in a 256 color terminal
Storing the values means we don't have to fork a tput process multiple times every time the prompt is displayed tput is only invoked 4 times during shell startup. Instead, we store the output of the tput command into variables, which are then used when $PS1 is expanded.
Note that we do not hard-code ANSI color escape sequences. If you want fancy colors in your prompt, consider using something manageable: This also turns off boldface ( tput bold), underline, etc. Tput sgr0 resets the colors to their default settings. For more details, see the terminfo(5) man page. Tput reads the terminfo database which contains all the escape codes necessary for interacting with your terminal, as defined by the $TERM variable.
#Linux remove ansi escape sequences using vi install
Tput bold echo "boldface (and still green)"Ĭygwin users: you need to install the ncurses package to get tput (see: Where did "tput" go in 1.7?) Do not hard-code ANSI color escape sequences in your program! The tput command lets you interact with the terminal database in a sane way:
