What's the DOS equivalent of the Unix find-grep combo for searching

Put in other words, more simply, how do I find within \freedos hierarchy
which text files have the string "foobar" occurring in them?
Looking for a DOS-centric way of doing that. As last resort I know I
can always install DJGPP's find and grep.
On PC DOS 7, there's find /s, but I don't think any other version of DOS
(including DR DOS or Win9x) supports that and I have no idea about FreeDOS.
Unfortunately, it seems FreeDOS does not support it as well:
C:\FREEDOS>find/?
FreeDOS Find, version 3.0
GNU GPLv2 - copyright 1994-2007 by Jim Hall, Eric Auer and Imre Leber
FIND: Prints all lines of a file that contain a string
FIND [ /C ] [ /I ] [ /N ] [ /V ] "string" [ file... ]
/C Only count the matching lines
/I Ignore case
/N Show line numbers
/V Print lines that do not contain the string
C:\FREEDOS>
That makes sense. It's on keel with MS-DOS 6.22, which is FreeDOS'
intention.
I did write my own FIND, but it doesn't support /S either. Using some
GNUey version of grep or fgrep is probably your best bet.
-uso.
