Windows recursive grep command-line

Question

I need to do a recursive grep in Windows, something like this in Unix/Linux:

grep -i 'string' `find . -print`

or the more-preferred method:

find . -print | xargs grep -i 'string'

I'm stuck with just cmd.exe, so I only have Windows built-in commands. I can't install Cygwin, or any 3rd party tools like UnxUtils on this server unfortunately. I'm not even sure I can install PowerShell. Any suggestions using only cmd.exe built-ins (Windows 2003 Server)?

The sys admins are locking down permissions on our servers. If anyone has any powershell suggestions, throw them out, and I'll see if we can install PowerShell. — Andy White
btw, I've found that in linux it's better to write: "find . |xargs grep -i string". The difference is that if find returns a very long list, you might exceed the maximum command length (it's happened to me), and you won't be able to grep at all. with xargs grep is called once per found file. — Nathan Fellman
Many versions of Grep, including Gnu Grep, offer built-in recursive search (gnu.org/software/grep/manual/…), so your search could be written as grep -i 'string' -R . which, like @NathanFellman suggests, avoids the problem of overlong commands. — Scott Centoni

findstr can do recursive searches (/S) and supports some variant of regex syntax (/R).

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

Reference.
