echo statement when find returns null
Hi,
How do you echo something once when a find statement returns null results?
This is when using mutiple locations and mutiple arguments.
The below find command the inner loop of a nested for loop where the outter loop holds the $args and the inner loop holds the locations.
find $location -name $args
Want the statement to print 'no such file' for the $args when all locations have been searched and not found a matching file in any of the locations. But just print the location and nothing else if the arg is found in any of the locations.
Sorry if this has been asked before I've searched and not found anything.

NOTES
Note
In PHP versions before 5.0.0 you must use ocicolumnname(3) instead. This name still can be used, it was left as alias of
oci_field_name(3) for downwards compatability. This, however, is deprecated and not recommended.
