grep可以在搜索过程中指定(include)或排除(exclude)某些文件。我们通过通配符来指 定所include文件或exclude文件。 目录中递归搜索所有的 .c和 .cpp文件: $ grep "main()" . -r --include *.c{c,cpp} #注意,some{str1,str2,str3}会扩展成somestr1,somestr2,somestr3。 在搜索中排除所有的readme文件:...
grep可以在搜索过程中使用通配符指定(include)或排除(exclude)某些文件。使用–include选项在目录中递归搜索所有的 .c和 .cpp文件: [root@m01 ~]# grep "/bin/bash" . -r --include=*.{sh,py} ./filestat.sh:#!/bin/bash ./pwd.sh:#!/bin/bash ./IFS_test.sh:#!/bin/bash ./IFS_test.sh:lin...
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...
If TYPE is without-match, when grep discovers null input binary data it assumes that the rest of the file does not match; this is equivalent to the -I option. If TYPE is text, grep processes a binary file as if it were text; this is equivalent to the -a option. When type is ...
--include-dir=pattern When pcregrep is searching the contents of a directory as a consequence of the -r (recursive search) option, only those subdirectories whose names match the pattern are included. (Note that the --include option does not affect subdirecto- ries.) The pattern is a ...
11. Why does the empty pattern match every input line? The grep command searches for lines that contain strings that match a pattern. Every line contains the empty string, so an empty pattern causes grep to find a match on each line. It is not the only such pattern: ‘^’, ‘$’, ...
'grep' assumes that a binary file does not match; this is equivalent to the '-I' option. If TYPE is 'text', 'grep' processes a binary file as if it were text; this is equivalent to the '-a' option.Warning:'--binary-files=text' might output binary garbage, which can have nasty...
He said hi to me. Where are you going? In anticipation of a unique situation, Examples include the following: "Many men smoke, but fu man chu." Does not match: He said "Hi" to me Where are you going? I'm headed to the
Ignore files larger than NUM in size. This does not apply to directories. --path-separator <SEPARATOR> Set the path separator to use when printing file paths. --sort <SORTBY> This flag enables sorting of results in ascending order.
管道输出用作Linux上grep的搜索规范,是指在Linux系统中,通过管道(pipe)将一个命令的输出作为另一个命令的输入,从而实现多个命令的组合使用。在这个问题中,我们将讨论如何使用管道输出来搜索符合特定规范的文本。 在Linux系统中,grep是一个非常有用的命令,用于在文本中搜索特定的字符串或模式。通过使用管道输出,我们可...
