the subdirectories of the current directory?
Thx.

Try grep -r -e '<pattern>' *

find . -name '*string*' -print

What is this -r switch?

grep: illegal option -- r

How about:
grep '<pattern>' `find .`
or better:
find . -exec grep 'pattern' {} \;

This works for me too:

ls -R */pattern

One drawback is it will recursively list all subdirectories.

But only if you have GNU grep installed, which is not the Solaris default.

% find . -type f -exec grep pattern {} /dev/null \;

I prefer find . -type f -exec grep -i "pattern" {} /dev/null \; to the
xargs one, coz.. in the later, SHELL limitations.. come into picture
and it may fail.. when the list gets too longer.

It shouldn't fail when the list gets too long. That's the whole
purpose of "xargs" -- to fit just as many arguments onto the command
line as will be allowed.

The "find"/"xargs" combo will fail, though, when the filename contains
newlines or other special characters, since there is a stream of
newline-separated filenames going from one to the other, and it's
possible to disturb the structure by adding your own newlines.

Not a specific reply to your's, but

may I point everyone to this nice little tool called tgrep from Sun.
It does a multithreaded recursive grep (very fast on multi cpu
machines).
I don't know where I got it from (source code), but a search on the Web
should give the right answer.

Apparently, according to http://www.bconnex.net/~ronw/tgrep/ , this
utility was written by someone else and used by Sun as an example of
threads-based programming. The reason I mention this is that the
version Sun used is said to be out of date.

Yes, but if you use the GNU version of these, there's a -print0
option on the find and a -0 option to xargs which prints and expects
a null-terminated string, respectively. We use this version and
it has been quite successful.
