总有一款适合你：Linux控制台界面让man命令显示彩色效果

Posted 2022-10-22 当年老王

在linux下面，让man命令显示彩色， 会比较醒目而且方便查看内容。不同的发行版，配置稍微有点差别。

在不改变 man命令的分页，也就是仍然采用 less命令分页的情况下，可以在

/etc/bashrc 或者 /etc/bash.bashrc 的末尾加入如下代码来显示彩色：

1） Debian 10 等：

#man color
export LESS=-R
export LESS_TERMCAP_mb=$'\\E[1;31m'     # begin blink
export LESS_TERMCAP_md=$'\\E[1;36m'     # begin bold
export LESS_TERMCAP_me=$'\\E[0m'        # reset bold/blink
export LESS_TERMCAP_so=$'\\E[01;44;33m' # begin reverse video
export LESS_TERMCAP_se=$'\\E[0m'        # reset reverse video
export LESS_TERMCAP_us=$'\\E[1;32m'     # begin underline
export LESS_TERMCAP_ue=$'\\E[0m'        # reset underline

2)  CentOS/Fedora系列：

#man for color
export LESS_TERMCAP_mb=$'\\E[1;31m'     # begin bold
export LESS_TERMCAP_md=$'\\E[1;36m'     # begin blink
export LESS_TERMCAP_me=$'\\E[0m'        # reset bold/blink
export LESS_TERMCAP_so=$'\\E[01;44;33m' # begin reverse video
export LESS_TERMCAP_se=$'\\E[0m'        # reset reverse video
export LESS_TERMCAP_us=$'\\E[1;32m'     # begin underline
export LESS_TERMCAP_ue=$'\\E[0m'        # reset underline
export GROFF_NO_SGR=1                  # for konsole and gnome-terminal

3) ArchLinux系列：

man() 
    env LESS_TERMCAP_mb=$(printf "\\e[1;31m") \\
        LESS_TERMCAP_md=$(printf "\\e[1;31m") \\
        LESS_TERMCAP_me=$(printf "\\e[0m") \\
        LESS_TERMCAP_se=$(printf "\\e[0m") \\
        LESS_TERMCAP_so=$(printf "\\e[1;44;33m") \\
        LESS_TERMCAP_ue=$(printf "\\e[0m") \\
        LESS_TERMCAP_us=$(printf "\\e[1;32m") \\
        man "$@"

4) Ubunt系列：

# Highlight the color man manual
export LESS_TERMCAP_mb=$'\\E[01;31m'
export LESS_TERMCAP_md=$'\\E[01;31m'
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[01;32m'

5）其它的：

# for color man page

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 "$@"

man() 
    LESS_TERMCAP_md=$'\\e[01;31m' \\
    LESS_TERMCAP_me=$'\\e[0m' \\
    LESS_TERMCAP_us=$'\\e[01;32m' \\
    LESS_TERMCAP_ue=$'\\e[0m' \\
    LESS_TERMCAP_so=$'\\e[45;93m' \\
    LESS_TERMCAP_se=$'\\e[0m' \\

    command man "$@"

6) 适用于 Fish shell：

$ vi ~/.config/fish/config.fish

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")
