Same as http://www.commandlinefu.com/commands/view/5876, but for bash.
This will show a numerical value for each of the 256 colors in bash. Everything in the command is a bash builtin, so it should run on any platform where bash is installed. Prints one color per line. If someone is interested in formatting the output, paste the alternative.
There are 9 alternatives - vote for the best!
I like the other three versions but one uses nested loops and another prints every color on a separate line. Both versions fail to reset colors before giving the prompt back.
This version uses the column command to print a table so all the colors fit on one screen. It also resets colors back to normal before as a last step.
This will show a numerical value for each of the 256 colors in ZSH. Everything in the command is a ZSH builtin, so it should run on any platform where ZSH is installed. Prints one color per line. If someone is interested in formatting the output, paste the alternative.
Shows the ?rendering? for each of the 256 colours in both the bold and normal variant. Using seq is helpful to get even lines, passing $((COLUMNS*2)) to column sort-of-handles the nonprintable characters.
Prints an easy-to-copy color code for each color.
