What is the closest thing to grep that comes standard on a Windows install?
提问by nc.
I'd like to do something like "dsquery * | grep asdf" on a Windows machine that I can't install anything on. Any ideas?
我想在无法安装任何东西的 Windows 机器上执行类似“dsquery * | grep asdf”的操作。有任何想法吗？
Thank you.
谢谢你。

The findstr command is what you're looking for. It's a little different than grep, but you can do some of the same things.
findstr 命令就是您要查找的内容。它与 grep 有点不同，但您可以做一些相同的事情。
C:\Working>findstr /?
Searches for strings in files.
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]filename[ ...]]
/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 filename 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 for.
[drive:][path]filename
Specifies a file or files to search.
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-y] Range: any characters within the specified range
\x Escape: literal use of metacharacter x
\ Word position: end of word
For full information on FINDSTR regular expressions refer to the online Command
Reference.

"find" appears since DOS ages. "findstr" is newer and feature richer than "find"
“查找”出现于 DOS 时代。“findstr”比“find”更新，功能更丰富
