由于wdiff接受在插入和删除的开头和结尾指定字符串的参数，您可以使用ANSI颜色序列作为这些字符串:

wdiff -n -w $'\033[30;41m' -x $'\033[0m' -y $'\033[30;42m' -z $'\033[0m' file1 file2

例如，这是比较两个CSV文件的输出:

来自2.2的例子wdiff的实际使用示例。

下面是另一个解决方案，它调用sed来插入适当的颜色ANSI转义序列，分别以红色、绿色和青色显示+、-和@行。

diff -u old new | sed "s/^-/$(tput setaf 1)&/; s/^+/$(tput setaf 2)&/; s/^@/$(tput setaf 6)&/; s/$/$(tput sgr0)/"

与此问题的其他解决方案不同，此解决方案没有显式地阐明ANSI转义序列。相反，它调用tput setaf和tput sgr0命令来生成ANSI转义序列，分别设置适当的颜色和重置终端属性。

要查看tput setaf的每个参数的可用颜色，使用以下命令:

for i in {0..255}; do tput setaf $i; printf %4d $i; done; tput sgr0; echo

下面是输出的样子:

下面是tput setaf和tput sgr0命令生成适当的ANSI转义序列的证据:

$ tput setaf 1 | xxd -g1
00000000: 1b 5b 33 31 6d                                   .[31m

$ tput setaf 2 | xxd -g1
00000000: 1b 5b 33 32 6d                                   .[32m

$ tput setaf 6 | xxd -g1
00000000: 1b 5b 33 36 6d                                   .[36m

$ tput sgr0 | xxd -g1
00000000: 1b 28 42 1b 5b 6d                                .(B.[m

彩色，字级差异输出

下面是你可以用下面的脚本和diff-highlight做的事情:

#!/bin/sh -eu

# Use diff-highlight to show word-level differences

diff -U3 --minimal "$@" |
  sed 's/^-/\x1b[1;31m-/;s/^+/\x1b[1;32m+/;s/^@/\x1b[1;34m@/;s/$/\x1b[0m/' |
  diff-highlight

(这要归功于@retracile对sed高亮的回答)

到目前为止还没有人提到delta。它支持带有语法高亮的语法彩色差异视图。
