To answer your question, I have liked UNIX Shells By Example by Ellie
Quigley (4th edition) it has good examples with explanations. The Linux
Command line and Shell Scripting Bible is a good teaching tool. A new
edition is due out next year but the current edition is still useful.

As to what you appear to want to do, if you require interactive logins (i.e.
ssh keys not set up for password-less logins) then bash is not the best
choice. For this you would want to use either Python (with pyexpect module)
or the Expect scripting language (Expect is an extension of the TCL
scripting language.
