在 Linux 中,我们可以使用diff命令对文件内容进行比较。使用-i选项可以进行不区分大小写的内容比较,示例如下:
$ diff -i comparison_file1.txt comparison_file2.txt 2,4c2 < < This line should be removed. < We have added multiple consecutive blank spaces. --- > We have added multiple consecutive blank spaces. 5a4 > Addition of a line若要忽略多个空白字符,可以使用-b选项,如下:
$ diff -bi comparison_file1.txt comparison_file2.txt 2,3d1 < < This line should be removed. 5a4 > Addition of a line在文件系统中,文件数量众多,手动查找特定文件几乎不可能。UNIX 和 Linux 提供了find命令来解决这个问题。
