dumb-init v1.2.5

dumb-init is a simple process supervisor that forwards signals to children. It is designed to run as PID1 in minimal container environments.

Optional arguments:

Run in single-child mode. In this mode, signals are only proxied to the direct child and not any of its descendants.
Rewrite received signal s to new signal r before proxying. To ignore (not proxy) a signal, rewrite it to 0. This option can be specified multiple times.
Print debugging information to stderr.
Print this help message and exit.
Print the current version and exit.
