Need help with this shell script

I made a shell script to make it easier to ssh, ssh with port forwarding, and mount sshfs on my 3 amazon servers. This is my first time making an advanced shell script and I keep getting the error:main.sh: line 98: syntax error: unexpected end of file
It asks me what I want to do. I type 1 and hit Enter so I can SSH to one of my servers. Then I get the error and the script ends. I don't know what's wrong.

Your problems is from having multiple if statements without closing them. For example with your if statements in lines 93 to 129 you have multiple if statements start and only one ends, I beleive you intended them to be a single statement, if that is the case you will want to use if..elif..fi, so the middle statements would start with elif.0

Thanks so much! I wonder how I could have forgotten about the elif statements when I was using them in the main one.0 -
We all forget little things like that every once in a while, I would also like to recommend adding your the remote server to your hosts file and adding port entries to your ssh.conf file for the remote hosts.
In addition, have you considered using an array of values for remote hosts in the script? this would make it easier to add additional hosts and reduce the redundancy.0 -
Hi Everyone,
I am currently studying for the linux exam. One of the questions is a bit vague. I would like someone to please explain why the answer is as such. It would be much appreciated.
I am having a hard time triing to read the statement. Can someone please explain it too me? I don't see where this "Hello" comes from either.
What is the output when the following shell script executes?
cat<<foobar
Hello foobar
Foobar
A. The contents of the file foobar.
B. Hello
C. No output but a file named foobar is created.
D. Hello foobar
E. Hello foobar foobar
Answer: D
Thanks in advance.
