Ssh: remote execute (en)

example

ssh user1@server1 command1
ssh user1@server1 'command2'
ssh user1@server1 'command1 | command2'

ssh user1@server1 date
ssh user1@server1 'df -H'
ssh root@nas01 uname -mrs
ssh root@nas01 lsb_release -a

ssh -t user@server "time sudo /home/user/script.sh"

Where:

-t   - provides terminal access if the script requests a password
sudo - to allow execution as superuser

Copy id_dsa.pub & id_rsa.pub

Ensure id_dsa.pub or id_rsa.pub is copied to the remote server,

ssh -l remoteuser remoteserver.com 'mkdir .ssh'
ssh -l remoteuser remoteserver.com 'touch ~/.ssh/authorized_keys'
cat ~/.ssh/id_dsa.pub | ssh -l remoteuser remoteserver.com 'cat >> ~/.ssh/authorized_keys'
