ACTION is 'read', which means that directories are read just as if they were ordinary files (some operating systems and file systems disallow this, and will cause 'grep' to print error messages for every direct

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...
grepOPTIONS PATTERN INPUT_FILE_NAMES OPTIONS部分可以指定0或多个。只有当没有使用"-e PATTERN"或"-f FILE"时,指定的PATTERN才被grep可视。可以指定0或多个INPUT_FILE_NAMES。 Command-line Options(命令行选项) 'grep'有大量选项可用:一些是POSIX.2中的,一些是GNU扩展的。长选项都是GNU扩展选项,即使它们来自于...
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 lines. grep在命名的输入文件中搜索与给定模式匹配的行。如果没有指定文件,或者给...

When type is binary, grep may treat non-text bytes as line terminators even without the -z option. This means choosing binary versus text can affect whether a pattern matches a file. For example, when type is binary the pattern q$ might match q immediately followed by a null byte, even...
