event or file wait scenario
i want to do 2 things
1) i should wait for a file called A.txt to fall on a specific path on the server
2) once the file arrives immediately another script called B.sh should be executed.
Could you please throw somelight on this.
Any code if already present that would be helpful.
Regards
Rajesh

Did not use 'wait' yet.
How I understand by now the wait works only for child processes, started background.

mongocursor.timeout
MONGOCURSOR.TIMEOUT(3) 1 MONGOCURSOR.TIMEOUT(3)
MongoCursor::timeout - Sets a client-side timeout for this query
SYNOPSIS
public MongoCursor MongoCursor::timeout (int $ms)
DESCRIPTION
A timeout can be set at any time and will affect subsequent queries on the cursor, including fetching more results from the database.
PARAMETERS
o $ms
- The number of milliseconds for the cursor to wait for a response. Use -1 to wait forever. By default, the cursor will wait
$30000 milliseconds (30 seconds).
RETURN VALUES
This cursor.
ERRORS
/EXCEPTIONS
Causes methods that fetch results to throw a MongoCursorTimeoutException if the query takes longer than the specified number of millisec-
onds.
EXAMPLES
Example #1
MongoCursor.timeout(3) example
In the following example, the driver will wait forever for the initial database response, and then wait 100ms for subsequent
responses.
<?php
$cursor = $collection->find();
$cursor->timeout(-1);
/* $cursor->hasNext() executes the query. An infinite timeout has been set, so
* the driver will wait as long as necessary for a response.
*/
while ($cursor->hasNext()) {
$cursor->timeout(100);
/* A timeout has now been set, so if the cursor needs to get more results
* from the database, it will only wait 100ms for a response.
*/
try {
print_r($cursor->getNext());
} catch (MongoCursorTimeoutException $e) {
echo "query took too long!";
}
}
?>
NOTES
Warning
This does not cause the MongoDB server to cancel long-running operations; it only instructs the driver to stop waiting for a
response and throw a MongoCursorTimeoutException after a set time. If you need to specify a server-side timeout for a query, con-
sider using MongoCursor::maxTimeMS.
