scripting doubts

Thanks all for your questions.

I'm stacked, though in another problem.
I have the script almost done but I'm having a small problem.
I'm doing an "egrep "REPLICATION CLIENT|ALL" | wc -l" after the mysql
-pwhatever -e "show grants for...etc" all this is redirected to a file using
normal ">".
for i in `cat file` do mysql -p -e "show grants etc.." "egrep "REPLICATION
CLIENT|ALL" | wc -l > /tmp/whatever basically.

/tmp/whatever has the following "format":

I use another "for" to read this file and decide whether the database has
the right privileges, if it has REPLICATION CLIENT or ALL privileges, "wc
-l" will return 1 or more than 1, if it doesn't have any of them it will be
a 0.

What's the problem? When I can't log into a mysql database (mostly cause it
is down) I got a "0", what I want is to discard these machines, so they're
not included in /tmp/whatever.
I tried doing: grep -v "ERROR" and doing a 2> /dev/null after the mysql -p
-e "show grants etc.." but it doesn't work.

Any ideas?

Thanks you all a lot.
