+## Bash command: ssh
+
+**Used to connect to a remote computer** ,for example `ssh 123.456.789.012` will try to establish a connection with that host. The
+address of the remote computer can be provided using an IP address or, if provided, an identifier.
+
+If the remote computer requires user login, the form `ssh username@remote_address` can be used, which will then prompt for the user
+password on successful connection.
