Problem with looping construct

Hi all

I have tried to search for this, but keep getting a MySQL db connect error, so am posing the question here, and taking a risk of incurring the wrath of the mods with my first post...

I have the following test script:
Code:
#!/bin/bash

HTTPD=`/bin/ps -axcu | /usr/bin/grep httpd >/dev/null; echo $?`

        while [ ${HTTPD} -eq 0 ]
        do
                echo "Apache is still running..." 
        done

echo "Apache has stoppped..."
echo "exiting..."

The final idea is to run the while loop until the state of httpd changes from 0 to 1 (i.e. from running to stopped). However, when I set this script to run, the output to stdout is obviously "Apache is still running...". Yet when I halt Apache with the command "sudo apachectl stop", the output to stdout is still "Apache is still running...", which quite clearly, is not true.

This is running on Mac OS 10.4.7 Server on a dual PPC Xserve

Anyone got a clue as to what I am doing wrong?

Mike

NAME
Apache::TestHandler - a few response handlers and helpers SYNOPSIS
package My::Test; use Apache::TestHandler (); sub handler { my ($r) = @_; my $result = do_my_test; Apache::TestHandler::ok1 $r, $result; } sub handler2 { my ($r) = @_; my $result = do_my_test; Apache::TestHandler::ok $r, $result; } DESCRIPTION
"Apache::TestHandler" provides 2 very simple response handler. FUNCTIONS
ok $r, $boolean The handler simply prints out "ok" or "not ok" depending on the optional $boolean parameter. If $boolean is omitted "true" is assumed. ok1 $r, $boolean This handler implements a simple response-only test. It can be used on its own to check if for a certain URI the response phase is reached. Or it can be called like a normal function to print out the test result. The client side is automatically created as described in <http://perl.apache.org/docs/general/testing/testing.html#Developing_Response_only_Part_of_a_Test>. $boolean is optional. If omitted "true" is assumed. same_interp_counter same_interp_fixup TODO SEE ALSO
