- Search only lines that match entirely in files: fgrep -x path/to/file1 path/to/file2 - 【重要】Count the number of lines that match the given string in a file: fgrep -c search_string path/to/file - Show the line number in the file along with the line matched: fgrep -n search...
在下面的例子中,搜索全部以“lines”开始以“empty”结束的字串,如搜索“lines[之间任意字]empty” ,并且忽略大小写。 $ grep -i "lines.*empty" demo_file Two lines above this line is empty. 正则表达式遵循的几个重复的操作 最多匹配一次 * 匹配零次或者任意多次 + 匹配一次以上 {n} 匹配n次 {n,}...
-v, --invert-match select non-matching lines // 搜索不匹配的行 -V, --version display version information and exit --help display this help text and exit Output control: // 输出控制 -m, --max-count=NUM stop after NUM matches -b, --byte-offset print the byte offset with output lines...

后n行,A记忆为(After) -B n 前n行,B记忆为(Before) -C n 前n行,后n行,C记忆为(Center) 举例 [root@localhost ~]# ifconfig | grep -A 2 "Link encap" eth0 Link encap:Ethernet HWaddr 00:0C:29:F3:38:15 inet addr:192.168.91.129 Bcast:192.168.91.255 Mask:255.255.255.0 ...
-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. ...
1. -A NUM,--after-context=NUM 除了列出符合行之外,并且列出后NUM行。 ex: $ grep -A 1 panda file (从file中搜寻有panda样式的行,并显示该行的后1行) 2. -a或--text grep原本是搜寻文字文件,若拿二进制的档案作为搜寻的目标, 则会显示如下的讯息: Binary file 二进制文件名 matches 然后结束。
2、显示/etc/passwd文件中不以/bin/bash结尾的行 3、找出/etc/passwd文件中,包含二位数字或者三位数的行。 4、显示/proc/meminfo文件中以大写或小写S开头的行;用三种方式实现。 5、使用echo输出一个绝对路径,使用egrep取出路径名,类似执行dirname /etc/passwd 的结果。
Instead of showing every matched line, show the number of lines that match. --color[=<when>] Show colored matches. The value must be always (the default), never, or auto. --no-color Turn off match highlighting, even when the configuration file gives the default to color output. Same ...
