- Search for a pattern in all files recursively in a directory, ignoring binary files: egrep --recursive --binary-files=without-match "search_pattern" path/to/directory - 【重要】Search for lines that do not match a pattern: egrep --invert-match "search_pattern" path/to/file fgrep命令总结...
-c or --count option is also used, grep does not output a count greater than NUM. When the -v or --invert-match option is also used, grep stops after outputting NUM non-matching lines. 在NUM匹配行之后停止读取文件。如果输入是来自常规文件的标准输入,并且NUM匹配行是输出的,则grep确保将标准...
-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 FILE name Context control: // 上下文控制 -B, --before-context=NUM prin...
-v, --invert-match Invert matching. Show lines that do not match the given patterns. -w, --word-regexp Only show matches surrounded by word boundaries. This is roughly equivalent to putting \b before and after all of the search patterns. -x, --line-regexp Only show matches surrounded ...

Linux系统中grep命令是一种强大的文本搜索工具,它能使用正则表达式搜索文本,并把匹 配的行打印出来。grep全称是Global Regular Expression Print,表示全局正则表达式版本,它的使用权限是所有用户。
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: grep bash /etc/passwd 输出应该是这样的: ...
To match blank lines, use the pattern ‘^[[:blank:]]*$’. 即,grep 命令认为每一行都包含空字符串,所以提供的匹配模式为空字符串时,会匹配到所有行。 匹配模式写为 '^'、'$'、'.*',也是会匹配到所有行。 如果想要匹配空行,匹配模式可以写为 '^$',空行只包含一个行末的换行符。 如果想要匹配只...
是指通过grep命令在文本文件中查找匹配某个模式的行,并返回匹配行的数量。 grep是一种强大的文本搜索工具,可以在文件中查找指定的字符串模式,并将匹配的行打印出来。使用grep获取行数可以通过以下...
