# Genders and PDSH

Genders and PDSH grant a way to control multiple nodes at once. As such it will not function on a single node environment. To test its functionality:

Show a space separated list of all the nodes with the gender <gender>.
```
nodeattr -s <gender>
```
Execute the uptime command on all nodes of the gender <gender>
```
pdsh -g <gender> uptime
```
This should show the time since last boot for each node.

All information about Genders and PDSH can be found the dedicated documentation section.
