    由于不满意1.0版本的UI风格,星博客V2.0今日进入开发阶段

Mac/Linux系统Terminal中不同文件类型的颜色
ex fx cx
directory symbolic link socket
dx bx  
pipe executable  
eg ed ab
block special character special executable with setuid bit set
ag ac ad
executable without setuid / black / cyan directory with sticky / black / green directory without sticky / black / brown

Now, let’s learn how we can configure our Terminal to obtain the colors of the figure.

Terminal custom colors

Colors can be changed using the LSCOLORSvariable in the ~/.zsh_profile. By default is set to

LSCOLORS=exfxcxdxbxegedabagacad

where the string exfxcxdxbxegedabagacad is a concatenation of pairs of the format TB, where T is the text color and B is the Background color.

The order of these pairs correspond to:

  1. directory
  2. symbolic link – special kind of file that contains a reference to another file or directory.
  3. socket – special kind of file used for inter-process communication.
  4. pipe – special file that connects the output of one process to the input of another.
  5. executable
  6. block special – a kind of device file.
  7. character special – a kind of device file.
  8. executable with setuid bit set (setuid is a short for set user ID upon execution).
  9. executable with setgid bit set (setgid is a short for set group ID upon execution).
  10. directory writable to others, with sticky bit – only the owner can rename or delete files.
  11. directory writable to others, without sticky bit – any user with write and execution permissions can rename or delete files.

And the different letters correspond to:

  • a black
  • b red
  • c green
  • brown
  • blue
  • f magenta
  • g cyan
  • h light grey
  • x default color

The same letters in uppercase indicate Bold.

The Terminal default colors, described by exfxcxdxbxegedabagacad, and ordered by file type / text color / background color, are:

  1. ex –> directory / blue / default
  2. fx –> symbolic link / magenta / default
  3. cx –> socket / green / default
  4. dx –> pipe / brown / default
  5. bx –> executable / red / default
  6. eg –> block special / blue / cyan
  7. ed –> character special / blue / brown
  8. ab –> executable with setuid / black / red
  9. ag –> executable without setuid / black / cyan
  10. ac –> directory with sticky / black / green
  11. ad –> directory without sticky / black / brown

You can change the colors of your terminal by creating a new concatenated string, like
GxFxCxDxBxegedabagaced, and writing in the .bash_profile file the following line:

export LSCOLORS=GxFxCxDxBxegedabagaced

Enjoy the new Terminal layout!
