Recently we tried to establish an SSH connection from our VPS to a Shared Hosting environment trying to download some backup files via rsync. The process was successful but with one error notification:
stdin: is not a tty.
To fix this issue follow the steps below:
Login to your server where you wish to run rsycn
Go to the home directory of your user account.
cd /home/username
But normally, each time we logged in, We should automatically be in that user home directory.
Now edit a file named .bashrc using your favorite editor
nano .bashrc
Now add below line to the top of your .bashrc file:
[ -z "$PS1" ] && return
Now save that file and exit.
Done,now you will not encounter this error anymore.
