Hidasta
A simple cross-process signalling mechanism for shell scripts.
This is not an officially supported Google product
Why?
Sometimes you need multiple shell script processes to wait for an event.
How?
To wait:
hidasta -w $socket_path
, called from any number of processes, will block until signalled.
To signal:
hidasta -s $socket_path
just once. All instances currently waiting on the socket path will return, and the callers can continue.
Where?
$socket_path
is the path at which a new Unix Domain Socket will be created (and removed once signalled). Only works on Unix, but can use filesystem permissions to restrict who can signal or wait.
