ack在Windows上工作得很好(如果您有Perl)。我发现它在很多方面比grep更好。

多年来，我每天都在使用AJC Grep。我发现的唯一主要限制是文件路径被限制在255个字符，当遇到一个字符时它就会停止，而不仅仅是发出警告。这很烦人，但不经常发生。

我在64位的Windows 7 Ultimate上使用它，所以它的64位凭证没问题。

dnGREP是一个开源的Windows grep工具。它支持许多很酷的功能，包括:

撤销替换 能力搜索右键单击文件夹在资源管理器 高级搜索选项，如语音搜索和xpath 在PDF文件、档案和Word文档中搜索

恕我直言，它也有一个漂亮干净的界面:)

PowerShell的Select-String cmdlet在v1.0中很好，但在v2.0中明显更好。在最新版本的Windows中内置PowerShell意味着你在这里的技能总是有用的，而不需要先安装什么。

新的参数添加到Select-String: Select-String cmdlet现在支持新的参数，例如: 上下文:这个选项允许你查看匹配行之前和之后的行 -AllMatches:允许你看到一行中的所有匹配(以前，你只能看到一行中的第一个匹配) -NotMatch:等价于grep -v o -Encoding:指定字符编码

我发现为Get-ChildItem -Recurse .创建一个函数gcir比较方便，使用smarts来正确传递参数，并为Select-String创建一个别名ss。所以你可以这样写:

Gcir *.txt | ss foo

FINDSTR相当强大，支持正则表达式，并且具有在所有Windows机器上都可以运行的优点。

c:\> 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 occurances 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
  \<xyz    Word position: beginning of word
  xyz\>    Word position: end of word

用法示例:findstr text_to_find *或递归搜索findstr /s text_to_find *

我推荐AstroGrep。

它是免费的，开源的，并且有一个简单的界面。我一直用它来搜索代码。
