oracle@172.16.1.165 ' s Password:

2. Connected Remote host:

remotehost$

3. To temporarily return to the local host, enter the exit symbol: "~" and "control-z" combination.

When the input "~" is not immediately visible on the screen, it is displayed together when you press and press ENTER.
as follows, enter "~" in the remote host.
remotehost$ ~^z [suspend SSH]
[1]+ Stopped ssh 172.16.1.165
localhost$

4. It has now been returned to the local host, and the SSH remote client session is running in the UNIX background and can be viewed as follows:

localhost$ Jobs
[1]+ Stopped ssh 172.16.1.165

5. You can switch the SSH session process running in the background to the foreground and back to the remote host without entering a password

localhost$ FG%1
SSH 172.16.1.165
remotehost$
