/R	将搜索字符串作为一般表达式使用。
/S	在当前目录和所有子目录中搜索匹配文件。
/I	指定搜索不分大小写。

/O	在每个匹配行前打印字符偏移量。
/P	忽略有不可打印字符的文件。
/OFF[LINE]	不跳过带有脱机属性集的文件。
/A:attr	指定有十六进位数字的颜色属性。请见 "color /?"

/C:string	使用指定字符串作为文字搜索字符串。
/G:file	从指定的文件获得搜索字符串。 (/ 代表控制台)。
/D:dir	查找以分号为分隔符的目录列表。
strings	要查找的文字。

.	通配符:任何字符。

Windows Vista and later syntax

FINDSTR [/B] [/E] [/L] [/R] [/S] [/I] [/X] [/V] [/N] [/M] [/O] [/P] [/F:file] [/C:string] [/G:file]
[/D:dir list] [/A:color attributes] [/OFF[LINE]] strings [[drive:][path]file name[ ...]]

/B	Matches pattern if at the beginning of a line.
/E	Matches pattern if at the end of a line.
/L	Uses search strings literally.
/R	Uses search strings as regular expressions.
/S	Searches for matching files in the current directory and all subdirectories.
/I	Specifies that the search is not to be case-sensitive.
/X	Prints lines that match exactly.
/V	Prints only lines that do not contain a match.
/N	Prints the line number before each line that matches.
/M	Prints only the file name if a file contains a match.
/O	Prints character offset before each matching line.
/P	Skip files with non-printable characters.
/OFF[LINE]	Do not skip files with offline attribute set.
/A:attr	Specifies color attribute with two hex digits. See "color /?"
/F:file	Reads file list from the specified file(/ stands for console).
/C:string	Uses specified string as a literal search string.
/G:file	Gets search strings from the specified file(/ stands for console).
/D:dir	Search a semicolon-delimited list of directories.
strings	Text to be searched.
[drive:] [path:] file name	Specifies a file or files to search.

You'll need to use spaces to separate multiple search strings unless the argument is prefixed with /C. For example, 'FINDSTR "hello there" x.y' searches for "hello" or "there" in file x.y. 'FINDSTR /C:"hello there" x.y' searches for "hello there" in file x.y.

Regular expression quick reference:

.	Wildcard: any character.
*	Repeat: zero or more occurrences of previous character or class.
^	Line position: beginning of line.
$	Line position: end of line.
[class]	Character class: any one character in set.
[^class]	Inverse class: any one character not in set.
[x-z]	Range: any characters in the specified range.
\x	Escape: literal use of metacharacter x.
\ < xyz	Word position: beginning of word.
xyz\>	Word position: end of word.

findstr "computer help" myfile.txt

在上面的例子中，任何包含“computer help”的行都将被打印到屏幕上。

findstr /s "computer help" *.txt

与第一个示例类似，上面的代码将在当前目录和所有子目录的任何txt文件中找到包含“computer help”的行。

findstr /x /c:"computer help" *.txt

包含“计算机帮助”上的精确匹配的Match .txt文件;因此，不显示包含“computer help”或其他不精确匹配的文件。重要的是要认识到使用/x必须是一个完全匹配“计算机帮助”的行;换句话说，如果在同一条线上还有其他东西，那就不是完全匹配的。

findstr /n /i /c:"computer help" *

搜索任何包含“计算机帮助”的文件，不论其大小写，并显示找到文本的行。下面是一个示例，展示了上面示例的结果。

Computer Hopes free computer help.computer help, computer, hardware, help, hardware help,
support, video card, video card support, video card help, vlb, vesa, local, bus

findstr "computer help" myfile.txt

In the example above, any lines containing "computer help" would be printed to the screen.

findstr /s "computer help" *.txt

Similar to the first example, the code above would find lines containing "computer help" in any txt file in the current directory and all subdirectories.

findstr /x /c:"computer help" *.txt

Match .txt files that contain an exact match on "computer help"; therefore, files that contain "computer helps" or other non-exact matches are not shown. It's important to realize that using /x must be a line that exactly matches "computer help"; in other words, if anything else is on the same line, it's not an exact match.

findstr /n /i /c:"computer help" *

Search for any file containing "computer help" regardless of its case and display the line where the text is found. Below is an example of how the results in the example above may look.

Computer Hopes free computer help.computer help, computer, hardware, help, hardware help, 
support, video card, video card support, video card help, vlb, vesa, local, bus
