Zero's Uncle: dir_colors - 終端機下檔案目錄顯示顏色

2021-06-09

Debian 系的 Linux (Ubuntu、MintLinux、AntiX、MX Linux..) 都没 /etc/DIR_COLORS 這個檔，可以自行建立，或是建立 ~/.dircolors ( Centos 是在 ~/.dir_colors )

輸出預設值可以導入到 ~/.dircolors (注意會覆蓋 ~/.dircolors)

dircolors --print-database > ~/.dircolors
或 
dircolors -p > ~/.dircolors

# 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
# archives or compressed (bright red)

修改 ~/.dircolors 內的顏色設定值，(改目錄(di)為 green → 32 ，DIR 01;34 → DIR 00;32 )
其中 .tar 01;31 ，( .tar：.tar 附檔名， 01：粗體， 31：紅色 ) ( .tar是基本文件類型，01是效果，31是顏色 )
效果列表 ( Attribute codes:00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed )
- 00 - 預設
- 01 - 加粗
- 04 - 下底線
- 05 - 閃爍
- 07 - 反顯
- 08 - 暗(隱藏)
顏色列表
- Text color codes: 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white

export LS_COLORS

註：在 ~/.bashrc 最後，加入 export LS_COLORS=“di=32”，會把 LS_COLORS 中其他設定清掉，成為預設值，可以在終端機 ( terminator ) 測試一下
```
export LS_COLORS="di=00;35" 
```
在其他地方看到的：編碼-顏色/動作
