使用bat命令:

diff file1 file2 | bat -l diff

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
Title a game for YouTube
explorer "https://thepythoncoding.blogspot.com/2020/11/how-to-echo-with-different-colors-in.html"
SETLOCAL EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
  set "DEL=%%a"
)
echo say the name of the colors, don't read

call :ColorText 0a "blue"
call :ColorText 0C "green"
call :ColorText 0b "red"
echo(
call :ColorText 19 "yellow"
call :ColorText 2F "black"
call :ColorText 4e "white"

goto :Beginoffile

:ColorText
echo off
<nul set /p ".=%DEL%" > "%~2"
findstr /v /a:%1 /R "^$" "%~2" nul
del "%~2" > nul 2>&1
goto :eof

:Beginoffile

字符级色差: 安装ccdiff

ccdiff -r /usr/share/dict/words /tmp/new-dict

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

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

使用Vim:

diff /path/to/a /path/to/b | vim -R -

或者更好的是，VimDiff(或vim -d，打字更短)将并排显示两个、三个或四个文件之间的差异。

例子:

vim -d /path/to/[ab]

vimdiff file1 file2 file3 file4
