$ sidekiqctl --help
sidekiqctl - stop a Sidekiq process from the command line.

Usage: sidekiqctl <command> <pidfile> <kill_timeout>
 where <command> is either ‘quiet‘ or ‘stop‘
       <pidfile> is path to a pidfile
       <kill_timeout> is number of seconds to wait until Sidekiq exits
       (default: 10), after which Sidekiq will be KILL‘d

Be sure to set the kill_timeout LONGER than Sidekiq‘s -t timeout.  If you want
to wait 60 seconds for jobs to finish, use `sidekiq -t 60` and `sidekiqctl stop
 path_to_pidfile 61`

$ sidekiqctl stop ~/tmp/sidekiq.pid 
Sidekiq shut down gracefully.
