dumb-init v1.2.5
Usage: /usr/bin/dumb-init [option] command [[arg] ...]

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:
   -c, --single-child   Run in single-child mode.
                        In this mode, signals are only proxied to the
                        direct child and not any of its descendants.
   -r, --rewrite s:r    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.
   -v, --verbose        Print debugging information to stderr.
   -h, --help           Print this help message and exit.
   -V, --version        Print the current version and exit.
