NAME

       newpid - launch a command in a new PID namespace

SYNOPSIS

       newpid [-inNu] command

DESCRIPTION

       newpid uses the clone(CLONE_NEWPID) syscall to launch a command in a new PID namespace.
       The /proc filesystem is remounted so the new process IDs are also visible there.

OPTIONS

       -i  Use CLONE_NEWIPC to run in a new IPC namespace.

       -n  Use CLONE_NEWNET to run in a new network namespace.

       -N newpidname
           Use CLONE_NEWNET to run in a new network namespace, and join an existing network
           namespace. The name must start with newpid.

       -u  Use CLONE_NEWUTS to run in a new UTS namespace.

EXAMPLE

        $ newpid ps aux
        USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
        myon         1  0.0  0.0   4080    84 pts/3    S+   12:15   0:00 newpid ps aux
        myon         2  0.0  0.0  19984  1316 pts/3    R+   12:15   0:00 ps aux

        $ ./newpid -n ip link
        1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
            link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
