grep searches the named input FILEs for lines containing a match to the given PATTERN. If no files are specified, or if the file “-” is given, grep searches standard input. By default, grep prints the matching
-L, --files-without-match print only names of FILEs containing no match -l, --files-with-matches print only names of FILEs containing matches -c, --count print only a count of matching lines per FILE -T, --initial-tab make tabs line up (if needed) -Z, --null print 0 byte after...
-l Only the names of files containing selected lines are written to standard output. grep will only search a file until a match has been found, making searches potentially less expensive. Pathnames are listed once per file searched. If the standard input is searched, the string ``(standard ...

grep 命令最基本的用法是在文件中搜索字符串(文本)。 For example, to display all the lines containing the string bash from the /etc/passwd file, you would run the following command: 例如,要显示/etc/passwd 文件中包含字符串 bash 的所有行,可以运行以下命令: 代码语言:javascript 代码运行次数:0 运行...
