Often it’s required to execute on a remote server a command or a whole bash script.
\nNot everyone knows that through ssh<\/code> it’s possible to execute this task.<\/p>\n

Here’s the ssh syntax:<\/p>\n

usage: ssh [-1246AaCfgKkMNnqsTtVvXxY] [-b bind_address] [-c cipher_spec]\r\n           [-D [bind_address:]port] [-e escape_char] [-F configfile]\r\n           [-i identity_file] [-L [bind_address:]port:host:hostport]\r\n           [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]\r\n           [-R [bind_address:]port:host:hostport] [-S ctl_path]\r\n           [-w local_tun[:remote_tun]] [user@]hostname [command]<\/pre>\n
In the following example , the ls<\/code> command is run on the remote server.<\/p>\n
ssh remoteuser@remoteserver.com ls<\/pre>\n
To run a local script on the remote server, it’s required to upload it (through scp<\/code>), set it as executable and finally run it.<\/p>\n
The related example:<\/p>\n
scp myscript.sh remoteuser@remoteserver.com:\/remotedir\/myscript.sh\r\nssh remoteuser@remoteserver.com \"chmod +x \/remotedir\/myscript.sh\"\r\nssh remoteuser@remoteserver.com \/remotedir\/myscript.sh<\/pre>\n
Of course it’s required to type the password after each command (or to use a identity key file)<\/p>\n
Looking through the ssh<\/code> options it’s possible to find many other feature offered by this common command.<\/p>\n","protected":false},"excerpt":{"rendered":"
