Which commands will give me information about following using Terminal?

1. Kernel Version
2. Distribution version no.
3. All partition size of the HDD

I have, by default, 250MB of swap space in Ubuntu, and I want to expand it to a larger size. I need 800MB, which I think will be enough to open several applications without having to hit the current limit of swap. I hope someone can help me.

I've written this small utility script:

for h in $SERVER_LIST; do ssh $h "uptime"; done

When a new server is added to $SERVER_LIST, the script is stopped with:

The authenticity of host 'blah.blah.blah (10.10.10.10)' can't be established.
RSA key fingerprint is a4:d9:a4:d9:a4:d9a4:d9:a4:d9a4:d9a4:d9a4:d9a4:d9a4:d9.
Are you sure you want to continue connecting (yes/no)?

I've tried yes:

for h in $SERVER_LIST; do yes | ssh $h "uptime"; done

with no luck.

Is there a way to parametrize ssh to automatically accept any new key?

In older versions it was easy to create a launcher on my desktop. All I had to do is right click on my desktop and select the "create launcher" option.

How can I create such launchers now?

I have a friend who has got a computer that is not connected to the Internet. Is there any way to install software offline easily?
