grep like syntax with findstr
提问by bobbyrne01
ive been using grep a lot on linux lately but now i need to use findstr to carry out the same tasks on a windows machine and cant quite get the syntax just right.
我最近在 linux 上经常使用 grep，但现在我需要使用 findstr 在 Windows 机器上执行相同的任务，但不能完全正确地使用语法。
My grep command looks like:
我的 grep 命令看起来像：
grep "12/12/2011.\*followed by literal string" /myFile.txt
so this searches for the date and the literal string specified but can contain a mix of any other characters in between the two search terms by using .\*
所以这将搜索指定的日期和文字字符串，但可以通过使用在两个搜索词之间包含任何其他字符的混合 .\*
Anyone know how to convert this statement to findstr? thanks
任何人都知道如何将此语句转换为findstr？谢谢

The findstrcommand supports the /Roption to specify the search string as a regular expression. It's the default behavior, however, so you don't actually need to specify it:
该FINDSTR命令支持/R以指定搜索字符串作为一个正则表达式的选项。但是，这是默认行为，因此您实际上不需要指定它：
findstr "12/12/2011.*followed by literal string" myFile.txt
The above should give the same results as your grepexample.
以上应该给出与您的grep示例相同的结果。

In order to match a literal string, you should use the /Cflag, e.g: /C:"Your literal string here"Otherwise a space inside your regex is counted as an ORe.g. this:
为了匹配文字字符串，您应该使用/C标志，例如：/C:"Your literal string here"否则您的正则表达式中的空格被视为OR例如：
findstr "12/12/2011.*followed by literal string" myFile.txt
is the same as
是相同的
grep 12/12/2011.*followed|by|literal|string myFile.txt
In order to combine both, pipe the output of one into the other, like this:
为了将两者结合起来，将一个的输出通过管道传输到另一个，如下所示：
findstr "12/12/2011.*" myFile.txt | findstr /C:"followed by literal text"
