Commands tagged color

A bit different from some of the other submissions. Has bold and uses all c printable characters. Change the bs=value to speed up and increase the sizes of the bold and non-bold strings.

blue and yellow colored bash prompt for a Hanukkah celebration on your box

I've been using linux for almost a decade and only recently discovered that most terminals like putty, xterm, xfree86, vt100, etc., support hundreds of shades of colors, backgrounds and text/terminal effects.

This simply prints out a ton of them, the output is pretty amazing.

If you use non-x terminals all the time like I do, it can really be helpful to know how to tweak colors and terminal capabilities. Like:

Removes ANSI color and end of line codes to the [{attr1};...;{attrn}m format.

but you can't see the colors in that sample output :(

Same as the cool matrix style command ( http://www.commandlinefu.com/commands/view/3652/matrix-style ), except replacing the printed character with randomness. The command mentioned is much faster and thus more true to the matrix. However, mine can be optimized, but I wasted ... i mean spent enough time on it already

I like the fact the Patola's version uses only ones and zeros, but I also like the sparse output of the other versions. This one combines both of those features and eliminates some unnecessary cruft.

You can vary the sparseness by changing "$(($RANDOM % 5))" to another number. The number in this term "$(($RANDOM % 4))" controls how frequently the numbers are output bold.

I was looking for the fastest way to create a bunch of ansi escapes for use in echo -e commands throughout a lot of my shell scripts. This is what I came up with, and I actually stick that loop command in a function and then just call that at the beginning of my scripts to not clutter the environment with these escape codes, which can wreck havok on my terminal when I'm dumping the environment. More of a cool way to store escape ansi codes in an array. You can echo them like:

I usually just use with a function:

CC[15] has a background of bright green which is why it is separate. R resets everything, and X is my default font of bright white.

Those are just my favorite colors that I often use in my scripts. You can test which colors by running

This will diff your local version of the file with the latest version in svn. I put this in a shell function like so:

Same as above but slooooow it down

It's the same command as submitted, but first with a command to make all characters green. It's the only way it looked "matrix-like" on my gnome-terminal.

Another wall matrix :)

This will create a permanent alias to colorize the search pattern in your grep output

Solves "tr" issues with non C-locales under BSD-like systems (like OS X)

Simple way to achieve a colored SVN diff

Get your colorized grep output in less(1). This involves two things: forcing grep to output colors even though it's not going to a terminal and telling less to handle those properly.

This is a simple command, but extremely useful. It's a quick way to search the file names in the current directory for a substring. Normally people use "ls *term*" but that requires the stars and is not case insensitive. Color (for both ls and grep) is an added bonus.

It colors the machine name and current directory different colors for easy viewing.
