在linux下的ls使用--color的參數時，雖然目錄有上色，但是顏色是深藍色很難辨識，加上老花加重，實在看不清楚，要怎麼修改呢？

這篇主要是參考[1]裡的說明，非常的詳細，節錄一部分符合我的需要。

一、修改 ~/.bashrc

最後面加入以下內容

LS_COLORS=$LS_COLORS:'di=0;94:'; export LS_COLORS;

修改完後執行生效

$ source ~/.bashrc

非常的簡單

二、設定方式說明

LS_COLORS 的格式如下：

類型=格式1;格式2;格式3...:類型=格式1;格式2;格式3...:...

類型可有多種格式，格式間用分號區隔 ';'，多個類型用冒號區隔 ':'。

例如

LS_COLORS=$LS_COLORS:'di=0;94:fi=1;4;41;93';

這樣目錄會是減藍色，一般檔案會是粗體黃色加底線，像這樣。

三、類型代號

bd = (BLOCK, BLK)   Block device (buffered) special file
cd = (CHAR, CHR)    Character device (unbuffered) special file
di = (DIR)  Directory
do = (DOOR) [Door][1]
ex = (EXEC) Executable file (ie. has 'x' set in permissions)
fi = (FILE) Normal file
ln = (SYMLINK, LINK, LNK)   Symbolic link. If you set this to ‘target’ instead of a numerical value, the color is as for the file pointed to.
mi = (MISSING)  Non-existent file pointed to by a symbolic link (visible when you type ls -l)
no = (NORMAL, NORM) Normal (non-filename) text. Global default, although everything should be something
or = (ORPHAN)   Symbolic link pointing to an orphaned non-existent file
ow = (OTHER_WRITABLE)   Directory that is other-writable (o+w) and not sticky
pi = (FIFO, PIPE)   Named pipe (fifo file)
sg = (SETGID)   File that is setgid (g+s)
so = (SOCK) Socket file
st = (STICKY)   Directory with the sticky bit set (+t) and not other-writable
su = (SETUID)   File that is setuid (u+s)
tw = (STICKY_OTHER_WRITABLE)    Directory that is sticky and other-writable (+t,o+w)
*.extension =   Every file using this extension e.g. *.rpm = files with the ending .rpm

四、格式及顏色代號

0   = default colour
1   = bold
4   = underlined
5   = flashing text (disabled on some terminals)
7   = reverse field (exchange foreground and background color)
8   = concealed (invisible)

顏色代碼 <下面圖是由[1]提供的shell執行結果>

最後提供我的設定 ~/.bashrc：

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

# User specific environment
if ! [[ "$PATH" =~ "$HOME/.local/bin:$HOME/bin:" ]]
then
PATH="$HOME/.local/bin:$HOME/bin:$PATH"
fi
export PATH

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
alias ll='ls --color -al'
alias vi='vim'

LS_COLORS=$LS_COLORS:'di=0;94:'; export LS_COLORS;

顏色就這麼多，加減用。
