- Run a command on two hosts, and print its output on each server inline:

`pssh {{[-i|--inline]}} {{[-H|--host]}} "{{host1}} {{host2}}" {{hostname --ip-addresses}}`
- Run a command and save the output to separate files:
`pssh -H {{host1}} -H {{host2}} -o {{path/to/output_dir}} {{hostname -i}}`
`pssh {{[-H|--host]}} {{host1}} {{[-H|--host]}} {{host2}} {{[-o|--outdir]}} {{path/to/output_dir}} {{hostname --ip-addresses}}`
- Run a command on multiple hosts, specified in a new-line separated file:
`pssh -i -h {{path/to/hosts_file}} {{hostname -i}}`
`pssh {{[-i|--inline]}} {{[-h|--hosts]}} {{path/to/hosts_file}} {{hostname --ip-addresses}}`
- Run a command as root (this asks for the root password):

`pssh -i -h {{path/to/hosts_file}} -p {{10}} '{{cd dir; ./script.sh; exit}}'`
`pssh {{[-i|--inline]}} {{[-h|--hosts]}} {{path/to/hosts_file}} {{[-p|-par]}} {{10}} '{{cd dir; ./script.sh; exit}}'`
