LSCOLORS Cheat-sheet

You can define color for each attribute with the help of LSCOLORS, when colors are enabled with CLICOLOR. This string is a concatenation of pairs of the format fb, where f is the foreground color and b is the background color. The default value is:

exfxcxdxbxegedabagacad Where,

The color and their code values are as follows:

Code Meaning (Color)

• a Black
• b Red
• c Green
• d Brown
• e Blue
• f Magenta
• g Cyan
• h Light grey
• A Bold black, usually shows up as dark grey
• B Bold red
• C Bold green
• D Bold brown, usually shows up as yellow
• E Bold blue
• F Bold magenta
• G Bold cyan
• H Bold light grey; looks like bright white
• x Default foreground or background

You can now customize it as per your need in ~/.bashrc:

• export CLICOLOR=1
• export LSCOLORS=cd GxFxCxDxBxegedabagaced I think this is a typo

When running a command that displays files in the shell, like the ls command, There are default colors set for each file type as follows:

On Linux systems, you can install some utilities package (can't remember which one) that includes a command dircolors That lets you manage coloration of files.

dircolors --print-database

This will display the current settings of all your file endings. You can edit this database as follows:

The output of the above command also explains what it does. Here are some experpts from that output:

Below are the color init strings for the basic file types. A color init string consists of one or more of the following numeric codes:

• Attribute codes:

~ 00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed

• Text color codes: 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
• Background color codes: 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white
• #NORMAL 00 # no color code at all
• #FILE 00 # regular file: use no color at all
• RESET 0 # reset to "normal" color

        DIR 01;34 # directory
    LINK 01;36 # symbolic link. (If you set this to 'target' instead of a
   # numerical value, the color is as for the file pointed to.)
  MULTIHARDLINK 00 # regular file with more than one link
  FIFO 40;33 # pipe
  SOCK 01;35 # socket
  DOOR 01;35 # door
  BLK 40;33;01 # block device driver
  CHR 40;33;01 # character device driver
  ORPHAN 40;31;01 # symlink to nonexistent file, or non-stat'able file ...
  MISSING 00 # ... and the files they point to
  SETUID 37;41 # file that is setuid (u+s)
  SETGID 30;43 # file that is setgid (g+s)
  CAPABILITY 30;41 # file with capability
  STICKY_OTHER_WRITABLE 30;42 # dir that is sticky and other-writable (+t,o+w)
  OTHER_WRITABLE 34;42 # dir that is other-writable (o+w) and not sticky
  STICKY 37;44 # dir with the sticky bit set (+t) and not other-writable
  # This is for files with execute permission:
  EXEC 01;32
  # List any file extensions like '.gz' or '.tar' that you would like ls
  # to colorize below. Put the extension, a space, and the color init string.
  # (and any comments you want to add after a '#')
  # If you use DOS-style suffixes, you may want to uncomment the following:
  #.cmd 01;32 # executables (bright green)
  #.exe 01;32
  #.com 01;32
  #.btm 01;32
  #.bat 01;32
  # Or if you want to colorize scripts even if they do not have the
  # executable bit actually set.
  #.sh 01;32
  #.csh 01;32

• defaults write com.apple.Terminal FocusFollowsMouse -string YES

from the command prompt. Only has to be done once.

- defaults write com.apple.Terminal FocusFollowsMouse -string NO to revert back to original.

You must include the entire color code information between the \[ and \] characters. Inside the tag, you must begin with either \033[ or \e[ to indicate to Bash that this is color information.

Both \033[ and \e[ do the same thing. \e[ is shorter so might be more convenient to use, but we’ll use \033[ here as it matches what’s used by default.

You must indicate the end of a colour tag with m\

So, every color tag will look like: \[\033[COLORm\] where foreground COLOR is:

• Black: 30
• Red: 31
• Green: 32
• Yellow: 33
• Blue: 34
• Purple: 35
• Cyan: 36
• White: 37

Bash also allows you to change the color of foreground text, add attributes like “bold” or “underline” to the text, and set a background color.

Attributes are added before the color number So, every attribute color tag will look like \[\033[ATTRIBUTE;COLORm\] or also, \e in place of \033

Where ATTRIBUTE is:

• 0 Normal text ( the default )
• 1 Bold or light text
• 2 Dim text
• 3
• 4 Underlined text
• 5 Blinking text
• 7 Reversed text
• 8 Hidden text.

Background colours cannot have attributes, but are:

• 40 Black
• 41 Red
• 42 Green
• 43 Yellow
• 44 Blue
• 45 Purple
• 46 Cyan
• 47\ White

So just changing the background colour to purple would be: \[\033[45m\]

You can specify both foreground and background color tags. For example, 42 represents a green background and 31 represents red text. So, to make the default prompt become red text on a green background, you’d use both the color prompts, one after another, OR, separated by a semicolon.

• PS1="\[\033[42m\]\[\033[31m\]\u@\h:\w\$ "
• PS1="\[\033[42m\]\[\033[01;31m\]\u@\h:\w\$ "

The background and foreground text colors keep going past the prompt unless you specify color code 00 clear the color information.

You can also use this tag within the variable to reset formatting back to default somewhere in your prompt. For example, the following line would end all coloring before the \$ character.

• PS1="\[\033[42m\]\[\033[31m\]\u@\h:\w\\[\033[00m\]\$ "

Some examples:

echo -e "\e[31;44mred on blue\e[0m"
echo -e "\e[34;41mblue on red\e[0m"

You can also change color of the PS1 prompt using tput. This works nicely when changing colour in a bash script output. /

NC=`tput setaf 0`
RED=`tput setaf 1`
GREEN=`tput setaf 2`
YELLOW=`tput setaf 3`
BLUE=`tput setaf 4`
PURPLE=`tput setaf 5`
CYAN=`tput setaf 6`
tput bold

echo "${RED}  tput setaf 1"
echo "${GREEN}  tput setaf 2"
echo "${YELLOW}  tput setaf 3"
echo "${BLUE}  tput setaf 4"
echo "${PURPLE}  tput setaf 5"
echo "${CYAN}  tput setaf 6"

This looks like this on my Macbook:

And if you :

• export PS1="\[$(tput bold)$(tput setb 4)$(tput setaf 7)\]\u@\h:\w $ \[$(tput sgr0)\]“

tput Color Capabilities:
tput setab [1-7] – Set a background color using ANSI escape
tput setb [1-7] – Set a background color
tput setaf [1-7] – Set a foreground color using ANSI escape
tput setf [1-7] – Set a foreground color
tput Text Mode Capabilities:
tput bold – Set bold mode
tput dim – turn on half-bright mode
tput smul – begin underline mode
tput rmul – exit underline mode
tput rev – Turn on reverse mode
tput smso – Enter standout mode (bold on rxvt)
tput rmso – Exit standout mode
tput sgr0 – Turn off all attributes
Color Code for tput:
0 – Black
1 – Red
2 – Green
3 – Yellow
4 – Blue
5 – Magenta
6 – Cyan
7 – White
