martin's questions

I set up a git repository on my Ubuntu machine as a server, which is on a home network. Then I SSH to this repository on the same computer or from another home computer. Login is fine. However, when I type a partial file or directory name at the terminal, then press tab, the cursor moves toward right on the terminal, without bringing the full file or directory name up as it normally does.

After I exit from the SSH server, the tab key works normally.

Edit:

Also, the →, ←, ↑ and ↓ keys don't work. When I press any of this, I get these at the terminal:

$ ^[[A^[[D^[[C^[[A

What could be the reason?

Add:

$ env

I have a file named like file.bin.gz.

I tried using gzip -d f.bin.gz to uncompress it, and got a .bin file.

Is the correct way to uncompress .bin files to use gzip -d? Also, .bin is a binary file, right?

this is my first time to install kubuntu. After i followed the steps to install and initially logged it, it displayed this page to me. It does't have the usual start or launch menu for me to access anything. I can't even start a terminal.

What's the problem? I can't even restart the system.
