assume(假定) that the file(二进制文件) is of type TYPE. By default, TYPE isbinary, and grep normally outputs either aone-line messagesaying that a binary file matches, or no message if there is no match. If TYPE iswithout-match, grep assumes that a binary file does not match; this i...
By default, TYPE is binary, and grep suppresses output after null input binary data is discovered, and suppresses output lines that contain improperly encoded data. When some output is suppressed, grep follows any output with a one-line message saying that a binary file matches. If TYPE is ...
By default grep searches case sensitive which means upper and lower case chars are interpreted as different. If we are looking for ahostnamein a file it is not important uppercase and lowercase so we will turn off case sensitivity for grep. We will provide-ioption to for case insensitive s...
1 grep grep 命令,用来搜索字符串所在位置,可以具体到不同文件,不同行; 在Linux 下,查看命令释义如下 zhaoc@ubuntu2004:~$ grep --help Usage: grep [OPTION]... PATTERNS [FILE]... Search for PATTERNS in each FILE. Example: grep -i 'hello world' menu.h main.c PATTERNS can contain multiple p...
grep:原生的grep命令,使用“标准正则表达式”作为匹配标准。 egrep:扩展的grep命令,相当于grep -E,使用“扩展正则表达式”作为匹配标准。 fgrep:简化版的grep命令,相当于grep -F,不支持正则表达式,只支持固定的字符串,但搜索速度快,系统资源使用率低。

Treat all files as ASCII text. Normally grep will simplyprint“Binary file ... matches”iffiles contain binary characters. Use of this option forces grep to output lines matching the specified pattern. -B num, --before-context=num Print num lines of leading context before each match. See al...
This switch will interpret a pattern as an extended regular expression. There’s a ton of different things you can do with this, but here’s an example of what it looks like to use a regular expression with grep. Let’s search a text document for strings that contain two consecutive ‘...
