### push already published packages to a device

## usage: fx push-package-no-publish [-d|--device <device_address>] [pkg1 pkg2 ...]
##
## Push packages to a device. One or more package names may be supplied. If no
## package name is suppled all packages in the build output will be pushed. The
## target must be reachable from the host and most already know the host's IP
## address. This assumes the package has already been published.
##
## See https://fuchsia.googlesource.com/docs/+/master/development/workflows/package_update.md
## for more information about using this workflow.
##
## optional arguments (must be first):
##   -d|--device         IP address of the target
