"grep" Command (SystemV/68 system)

How can i use grep command in order to look for into subdirectories?
I want to searche some word in a folder and in all its sub-directories in the same time.
(my system is based on "SystemV/68 R3V6"(UNIX))
Note:
1) "rgrep" program isn't installed on my system
2)-r option is not available ("grep -r" doesn't work)
Available options i got are: -b -l -n -s -v -i

If r isn't any option, much like on Solaris, what you'll end up doing is this:

grep -i blah *
grep -i blah */*
grep -i blah */*/*

Until there are no more sub directories, or there are so many subdirectories that grep doesn't work anymore.

Assuming your find has the -exec switch, you should also be able to do:

find . -name "*" -exec grep whatever /dev/null {} \;

The /dev/null is to give grep two arguments to force it to print the file name of matching lines.

That one will run faster, and doesn't need a /dev/null hack.

Code:

find . -type f -exec grep whatever {} +

If the "+" flag is unsupported by SVR3 find, use instead

Code:

find . -type f | xargs grep whatever
