| -d domain |
| | Specify a particular domain. The NIS domain of the local host system is used by default. If the local host’s domain name is not set, the domain name must be specified with this flag. |
| -t timeout |
| | Specify a timeout value in seconds. This timeout controls how long yppush will wait for a response from a slave server before sending a map transfer request to the next slave server in its list. |
| -j #parallel jobs |
| | The yppush utility normally performs transfers serially, meaning that it will send a map transfer request to one slave server and then wait for it to respond before moving on to the next slave server. In environments with many slaves, it is more efficient to initiate several map transfers at once so that the transfers can take place in parallel. The -j flag is used to specify the desired number of parallel jobs: yppush will initiate the specified number of transfers immediately and listen for responses. If the number of specified parallel jobs is less than the number of slave servers, yppush will initiate only the number of specified jobs and then wait for some of them to finish before starting any more. Note that yppush handles callbacks asynchronously, which means that it will collect and display the callback information received from ypxfr(8) as soon as it arrives, even it arrives before all of the map transfer requests have been sent. |
| -h host |
| | Can be used to transfer a map to a user-specified machine or group of machines instead of the list of servers contained in the ypservers map. A list of hosts can be specified by using multiple instances of the -h flag. |
| -p path |
| | By default, yppush expects all the local NIS maps to be stored under /var/yp. The -p flag can be used to specify an alternate path in the event that the system administrator decides to store the NIS maps somewhere else. |
| -v | Verbose mode: it causes yppush to print debugging messages as it runs. Specifying this flag twice makes yppush even more verbose. |
