Hmm...

Is it sensible to replace $x40 with X40 and $x38 with X38 on any line
anywhere for the purpose of this test? As the downstream test is only
interested in a line with HTTP request line that asks for a specific path
under objects/??/?{38}_?{40}, wouldn't it make more sense to replace
occurrences of only such line?

	sed -n \
            -e "s/PUT /OP " \
	    -e "s/MOVE /OP /" \
	    -e "s|/objects/$x2/$x38_$x40|WANTED_PATH_REQUEST|p" \
	    "$HTTPD_ROOT_PATH/access.log" |
	grep -e "\"OP .*WANTED_PATH_REQUEST HTTP/[.0-9]*\" 20[0-9] "
