diff[编辑 | 编辑源代码]

diffutils from version 3.4 includes the --color option (GNU mailing list).

$ alias diff 'diff --color=auto'

Alternatively, the following wrappers can be used:

  • colordiff — A Perl script wrapper for 'diff' that produces the same output but with pretty 'syntax' highlighting
https://www.colordiff.org/ || colordiff
  • cwdiff — A (w)diff wrapper to support directories and colorize the output
https://github.com/junghans/cwdiff || cwdiffAUR, cwdiff-gitAUR

grep[编辑 | 编辑源代码]



alias grep='grep --color=auto'


您还可以直接设置GREP_OPTIONS 环境变量,不过这有可能会影响到那些用到grep [1]的脚本:

 export GREP_COLOR="1;32"


less[编辑 | 编辑源代码]

环境变量[编辑 | 编辑源代码]

请在您的 shell 配置文件添加:

export LESS=-R
export LESS_TERMCAP_mb=$'\E[1;31m'
export LESS_TERMCAP_md=$'\E[1;36m'
export LESS_TERMCAP_me=$'\E[0m'
export LESS_TERMCAP_se=$'\E[0m'
export LESS_TERMCAP_so=$'\E[01;44;33m'
export LESS_TERMCAP_ue=$'\E[0m'
export LESS_TERMCAP_us=$'\E[1;32m'

值随您所愿修改,请参照:ANSI escape code

注意: The LESS_TERMCAL_xx variables is currently undocumented in less(1), for a detailed explanation on these sequences, see this answer.

Wrappers[编辑 | 编辑源代码]

您可直接开启less内置的代码高亮。先安装 软件包 source-highlight,再在您的Shell配置文件里添加以下:

export LESSOPEN="| /usr/bin/source-highlight-esc.sh %s"
export LESS='-R '


用户可以使用以下 less 命令列出一个压缩包里的文件列表:

$ less compressed_file.tar.gz
==> use tar_file:contained_file to view a file in the archive
-rw------- username/group  695 2008-01-04 19:24 compressed_file/content1
-rw------- username/group   43 2007-11-07 11:17 compressed_file/content2
compressed_file.tar.gz (END)

读取标准输入时彩色化输出[编辑 | 编辑源代码]

注意: 建议将这些 #环境变量 添加到 ~/.bashrc or ~/.zshrc. 因为本节完全基于: export LESS=R 写成

当你运行一个命令和使用管道连接 标准输出 (stdout) 到 less 作为分页视图 (e.g. yaourt -Qe --date | less), 你也许会发现输出不再是彩色化的. 这通常是因为该程序试图检测如果其 stdout 是交互式终端, 在这种情况下将输出彩色化文本,否则输出未着色文本. 当你想重定向 stdout 到一个文件中,这是一个很好的行为, e.g. yaourt -Qe --date > pkglst-backup.txt. 但是,当你想在 less 浏览输出时这将不是很好的行为.

一些程序提供禁用交互式 tty 检测的选项:

# dmesg --color=always | less

如果程序不提供任何类似选项,可以欺骗程序相信stdout 是交互式终端,有几种可行方式:

  • stdoutisatty 是一个用c写成的小程序, 它可以调用 "fake interactive tty". 你可以通过 AUR: stdoutisattyAUR安装. 用法示例:
$ stdoutisatty yaourt -Qe --date | less
  • unbuffer 是一个基于 shTcl 的很好的 (手册比程序本身还要长), 古老的脚本. unbuffer 附带 expect. 我们只需要这样使用:
$ unbuffer yaourt -Qe --date | less

zptyzsh 的一个模块, 这里有一个来自 依云[2] 的小函数, 将其放入 ~/.zshrc:

zmodload zsh/zpty

pty() {
	zpty pty-${UID} ${1+$@}
	if [[ ! -t 1 ]];then
		setopt local_traps
		trap '' INT
	zpty -r pty-${UID}
	zpty -d pty-${UID}

ptyless() {
	pty $@ | less


$ ptyless program

通过管道转接到其它程序 (less in this example):

$ pty program | less

ls[编辑 | 编辑源代码]


alias ls='ls --color=auto'


eval $(dircolors -b)

man[编辑 | 编辑源代码]


有两种常用的实现man手册页彩色显示的方法:使用 mostless .

使用 less[编辑 | 编辑源代码]

You can set various LESS_TERMCAP_* environment variables to change how it highlights text. For example, LESS_TERMCAP_md is used for bold text and LESS_TERMCAP_me is used to reset to normal text formatting[3].

In Bash, the escape sequences you can use are the same ones from Bash/Prompt customization and these variables can be defined in a function wrapping the man command:

man() {
    LESS_TERMCAP_md=$'\e[01;31m' \
    LESS_TERMCAP_me=$'\e[0m' \
    LESS_TERMCAP_se=$'\e[0m' \
    LESS_TERMCAP_so=$'\e[01;44;33m' \
    LESS_TERMCAP_ue=$'\e[0m' \
    LESS_TERMCAP_us=$'\e[01;32m' \
    command man "$@"

For Fish you could accomplish this with:

set -xU LESS_TERMCAP_md (printf "\e[01;31m")
set -xU LESS_TERMCAP_me (printf "\e[0m")
set -xU LESS_TERMCAP_se (printf "\e[0m")
set -xU LESS_TERMCAP_so (printf "\e[01;44;33m")
set -xU LESS_TERMCAP_ue (printf "\e[0m")
set -xU LESS_TERMCAP_us (printf "\e[01;32m")

Remember to source your config or restart your shell to make the changes take effect.

For a detailed explanation on these variables, see this answer. Bash/Prompt customization#Examples has some (non-Bash-specific) examples of escape sequences that can be used.

Using most[编辑 | 编辑源代码]

The basic function of 'most' is similar to less and more, but it has a smaller feature set. Configuring most to use colors is easier than using less, but additional configuration is necessary to make most behave like less.

pacman 安装软件包 most.


DEFINE     pager     most -s


$ man whatever_man_page

通过修改~/.mostrc(不存在的话请自行创建)或全局配置文件 /etc/most.conf。示例~/.mostrc:

% Color settings
color normal lightgray black
color status yellow blue
color underline yellow black
color overstrike brightblue black


% less-like keybindings
unsetkey "^K"
unsetkey "g"
unsetkey "G"
unsetkey ":"

setkey next_file ":n"
setkey find_file ":e"
setkey next_file ":p"
setkey toggle_options ":o"
setkey toggle_case ":c"
setkey delete_file ":d"
setkey exit ":q"

setkey bob "g"
setkey eob "G"
setkey down "e"
setkey down "E"
setkey down "j"
setkey down "^N"
setkey up "y"
setkey up "^Y"

setkey search_backward "?"
setkey bob "p"
setkey goto_mark "'"
setkey find_file "E"
setkey edit "v"

Using X resources[编辑 | 编辑源代码]

A quick way to add color to manual pages viewed on xterm/uxterm or rxvt-unicode is to modify ~/.Xresources.

xterm[编辑 | 编辑源代码]

*VT100.colorBDMode:     true
*VT100.colorBD:         red
*VT100.colorULMode:     true
*VT100.colorUL:         cyan

which replaces the decorations with the colors. Also add:

*VT100.veryBoldColors: 6

if you want colors and decorations (bold or underline) at the same time. See xterm(1) for a description of the veryBoldColors resource.

rxvt-unicode[编辑 | 编辑源代码]

URxvt.colorIT:      #87af5f
URxvt.colorBD:      #d7d7d7
URxvt.colorUL:      #87afd7


$ xrdb -load ~/.Xresources

Launch a new xterm/uxterm or rxvt-unicode and you should see colorful man pages.

This combination puts colors to bold and underlined words in xterm/uxterm or to bold, underlined, and italicized text in rxvt-unicode. You can play with different combinations of these attributes (see the sources (archived) of this item).

pacman[编辑 | 编辑源代码]

Pacman has a color option. Uncomment the Color line in /etc/pacman.conf.

Virtual console[编辑 | 编辑源代码]


原因:Lacks clarity on what "the colors" are, i.e. in #Virtual console they are about the representations of the 16 base colors (RGB values for yellow, red, blue, etc.), while in #Login screen they are about the base colors themselves. See also console_codes(4) and User:Isacdaavid/Linux_Console(在Talk:在终端输出彩色讨论)

The colors in the Linux virtual console—see console(4)[失效链接 2017-09-06]—running on the framebuffer can be changed. This is done by writing the escape code \\e]PXRRGGBB, where X is the hexadecimal index of the color from 0-F, and RRGGBB is a traditional hexadecimal RGB code.

For example, to reuse existing colors defined in ~/.Xresources, add the following to the shell initialization file (such as ~/.bashrc):

if [ "$TERM" = "linux" ]; then
    _SEDCMD='s/.*\*color\([0-9]\{1,\}\).*#\([0-9a-fA-F]\{6\}\).*/\1 \2/p'
    for i in $(sed -n "$_SEDCMD" $HOME/.Xresources | awk '$1 < 16 {printf "\\e]P%X%s", $1, $2}'); do
        echo -en "$i"

Login screen[编辑 | 编辑源代码]

The below is a colored example of the virtual console login screen in /etc/issue. Create a backup of the original file with mv /etc/issue /etc/issue.bak as root, and create a new /etc/issue:

X window system[编辑 | 编辑源代码]

Most Xorg terminals, including xterm and urxvt, support at least 16 basic colors. The colors 0-7 are the 'normal' colors. Colors 8-15 are their 'bright' counterparts, used for highlighting. These colors can be modified through X resources, or through specific terminal settings. For example:

! Black + DarkGrey
*color0:  #000000
*color8:  #555753
! DarkRed + Red
*color1:  #ff6565
*color9:  #ff8d8d
! DarkGreen + Green
*color2:  #93d44f
*color10: #c8e7a8
! DarkYellow + Yellow
*color3:  #eab93d
*color11: #ffc123
! DarkBlue + Blue
*color4:  #204a87
*color12: #3465a4
! DarkMagenta + Magenta
*color5:  #ce5c00
*color13: #f57900
!DarkCyan + Cyan (both not tango)
*color6:  #89b6e2
*color14: #46a4ff
! LightGrey + White
*color7:  #cccccc
*color15: #ffffff
警告: Color resources such as foreground and background can be read by other applications (such as emacs). This can be avoided by specifiying the class name, for example XTerm.foreground.
