In the left had pane choose the profile you want to adjust, and in the right hand pane select the Colors tab. TIPS FOR HOW TO ADJUST YOUR OWN SYSTEM'S COLORSįrom the GNOME Terminal menu select Edit | Preferences. But you can edit DIR_COLORS used by dircolors (see notes above) to adjust things with LS_COLORS. No amount of messing in GNOME Terminal (below) seems to affect these colors. Note that there are some reverse video folders and files that display funny with ls (e.g. ![]() # <- where this value is created from /etc/DIR_COLORSįor reference, how I'm enabling colors in various commands in /etc/profile (which is read whenever a login is done, (including $ bash -login)) is below, at the very bottom of this answer. # /etc/DIR_COLORS is a data file from: $ dircolors -p > /etc/DIR_COLORSĮval "$(dircolors -b /etc/DIR_COLORS)" # This reads /etc/DIR_COLORS # = Create DEFAULT LS_COLORS ENVIRONMENT VARIABLE = I call dircolors early in my /etc/profile where I use it to set and export LC_COLORS. To read DIR_COLORS and create and export the LS_COLORS (ANSI color codes are escapeĬ) Run dircolors again, this time in both Request a particular ANSI color combination. For example, any filenames like *.png can The ANSI color code system is a very old system, first originating on stand-alone hardware terminals.Ī colored text request looks something like: /etc/DIR_COLORS # to produce DIR_COLORS template fileī) Hand edit /etc/DIR_COLORS to adjust ANSI color codes that will be outputįor various things to display. Here I emphasize that these are only requests to the terminal, which has the final decision of how to display them. What are requested, and what are finally output to your terminal screen that you'll see, can be two different sets of colors.ġ) Any text based program or shell built-in, can by design, output ANSI (American National Standards Institute) color-request escape codes. Your terminal emulator can then choose to display different colors than those requested. I stress request to be displayed, because the colors a command requests are only what is sent to your terminal emulator. To do that, you probably want to be adjusting the color palette in your terminal emulator.įor instance, dircolors is not used to adjust the colors requested by grep, vi, tmux, or man.ĭircolors is used to adjust the colors that the commands ls and tree request to be displayed when displaying your filenames. wav 01 04 05 38 5 160 48 5 240 # Pure madness: make bold (01), underlined (04), blink (05), fg color 160, and bg color 240!ĭircolors (short for Directory Colors) can't be used to modify colors globally. flac 48 5 240 # Set bg color to color 240 The format for 256 color escape codes is 38 5 colorN for foreground colors and 48 5 colorN for background colors. They won't work on the Linux text console, for example. You can use xterm's 256 color escape codes in your dircolors file, but be aware that they'll only work for xterm compatible terminals. I just bring this up to point out that setting dircolors for truly everybody depends on the shell they use.Īs for where dircolors gets its settings from, when you don't specify a file it just uses some builtin defaults. Your distribution might have zsh do that already. # $(dircolors) effectively sets the LS_COLORS environment variable.įor zsh, you'd either put it in /etc/zshrc or arrange for zsh to read /etc/profile on startup. To have this environment variable take effect system-wide, put it in your shell's startup file.įor bash, you'd put this in /etc/profile: # `dircolors` prints out `LS_COLORS='.' export LS_COLORS`, so eval'ing dircolors is merely a convenient way to generate this environment variable. Thanks to a revamped interface plus some powerful and accessible features, GraphicConverter is a solid photo application for managing, converting and editing your pictures.Ls takes it color settings from the environment variable LS_COLORS. GraphicConverter lacks the more advanced web sharing features that are integrated into iPhoto however. Although there clearly aren't as many editing tools as in Aperture or Lightroom, GraphicConverter comes with a very wide list of filters and effects that you can place onto your images all of which are accessible from the menu bar.
