Thanks Andreas!

Here is what I ended up doing:

   find /COMM/DOC/html -type f | xargs -n1 -i grep -il " database " {}

What I wanted (and received) was a list of the files which contain the
string " database " (notice the blanks before and after), and that is what
the above command generates.

Note that in my case I specified "-il" for grep so that it would be case
insensitive (-i) and only list the name of the files containing the search
word (-l).

As Mark Bixby and Andreas Schmidt both noted (and very kindly), my mistake
was trying to use the "ls" command instead of "find".

The "-type f" option on the "find" command causes "find" to only list files
(as opposed to listing files and directories).

The "xargs" command takes the output of the find command and creates
individual commands from it ("grep" commands in this case).  There are
really three parameter groups to the "xargs" command.  First, the "-n1"
tells "xargs" to use only one file name at a time.  Second, the "-i" tells
"xargs" to replace any instance of "{}" with the file name.  Third, the
"grep -il ' database ' {}" provides the pattern (or template) of the
command(s) that "xargs" is to create from the list the "find" command
generates.

Thanks again to all who wrote!  Once again, the HP3000-L comes through!
