diff的手册页没有建议从内部进行着色的解决方案。请考虑使用色差。它是diff的包装器，产生与diff相同的输出，除了它使用彩色语法高亮显示来增强输出以增加可读性:

diff old new | colordiff

或者是:

colordiff old new

安装:

Ubuntu/Debian: sudo apt-get install colordiff OS X: brew install colordiff或port install colordiff

对我来说，我找到了一些解决方案:这是一个有效的解决方案

@echo off

SETLOCAL EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (

call :ColorText 0a "blue"
call :ColorText 0C "green"
call :ColorText 0b "red"

call :ColorText 19 "yellow"
call :ColorText 2F "black"
call :ColorText 4e "white"

goto :Beginoffile

:ColorText
echo off

:Beginoffile

我使用grc(通用着色器)，它允许您对包括diff在内的许多命令的输出进行着色。

它是一个Python脚本，可以封装在任何命令中。因此，不是调用diff file1 file2，而是调用grc diff file1 file2来查看着色的输出。我有别名diff到grc diff使它更容易。

你可以改变Subversion配置使用colordiff:

~ / .subversion / config.diff

 ### Set diff-cmd to the absolute path of your 'diff' program.
 ###   This will override the compile-time default, which is to use
 ###   Subversion's internal diff implementation.
-# diff-cmd = diff_program (diff, gdiff, etc.)
+diff-cmd = colordiff

我最喜欢的选择是vdiff <file1> <file2>函数(我忘记从哪里得到它)。

它将在Vim中并排打开两个窗口，以清楚地看到两个文件之间的差异。

vdiff () {
    if [ "${#}" -ne 2 ] ; then
        echo "vdiff requires two arguments"
        echo "  comparing dirs:  vdiff dir_a dir_b"
        echo "  comparing files: vdiff file_a file_b"
        return 1
    fi

    local left="${1}"
    local right="${2}"

    if [ -d "${left}" ] && [ -d "${right}" ]; then
        vim +"DirDiff ${left} ${right}"
    else
        vim -d "${left}" "${right}"
    fi
}

将这个脚本放在您的(.alias)或(.zshrc)中，然后使用 Vdiff <file1> <file2>. Vdiff <file1>。

结果如下:
