Question posted in 
I am new to linux so please go easy and talk slow =)
In Plesk I have some options for accessing the server over SSH. I just want to connect, add my public key and run rsync for backup.
- What is the difference between these options?
- Which option should I choose?
- What are these? They look like directories to me.
Access to the server over SSH:
- /bin/sh
- /bin/bash
- /sbin/nologin
- /bin/tcsh
- /bin/csh
- /bin/ksh
- /bin/bash (chrooted)
- /bin/rbash
Here is an image of the Plesk control panel:

Most of options are various Unix shells. A shell is basically what interprets the text that you type in the window. Some people prefer one shell over others. If you are not familiar with any shell in particular, pick one based on your needs Comparison Chart
If you don’t know, you should use /bin/bash. It’s the most popular, and will be the easiest for you to get help using. That said, they all do the same thing, just in slightly different ways.
Use /bin/bash
These are different options for default shell given to users who connect via SSH
If you haven’t used any of these shells before, I think bash is the best option for you. Most tutorials and articles for linux commands online assume you are using bash.
However, you have two options for bash:
/bin/bashand/bin/bash (chrooted).To do backups, you will probably need the bash to have full access to execute all commands.
I’m not sure whether you can get what you want done with a chrooted bash.
Basically, chrooted bash is for avoiding mishaps.
