    Put very simply, it means that "no matter who, or where, you are,
    'postmaster' isn't running."

    'ps' doesn't care which directory you're in, it just lists the running
    processes.

    The output is piped to 'grep postmaster' which looks for the string
    "postmaster".

    Since there is now a running process (namely; 'grep postmaster') - the
    output is piped further into 'grep -v grep' which *inverts* the match,
    discarding anything containg the string "grep", leaving... nothing...

    Have a look at 'grep --help'
