rsync exits with the message "stdin is not a tty"
I want to use rsync to my remote server for which I have SSH access. I use the following command:
rsync -e 'ssh -p 22222' -rtz --delete content_dir/ user@example.com:/home/user/public_html
After entering the command, it asks for the password for the remote location. When I type it, it exits with the message,
stdin: is not a tty
How do I supply the password to rsync? The method suggested should also work when I use it in a shell script.
You need to add:
[ -z "$PS1" ] && return
to the beginig of .bashrc that is located in your home dir.
The password is being accepted here, as you've stated yourself the operation does happen.
The error message "stdin: is not a tty" is due to something in the startup script on your server attempting to process an action that should only happen for interactive logins (when you connect with ssh direct to the server, etc).
[ -z "$PS1" ] && return
solves the problem but it checks whether the prompt string length equals to zero and if it does then exits. Although $PS1 will not be set in a non-interactive shell, $PS1 being of zero length doesn't ultimately mean that the shell is not interactive.
Better approach is to check the shell's current options using $-
. For example [[ $- != *i* ]] && return
.
