Recently my company is moving an application system from mainframe z/OS to AIX. I have some experience on Ubuntu, but am completely new to AIX 6.1. Just wondering a few question:

1. We use putty to connect to the AIX servers, but putty is very difficult to operate. You cannot use up arrow to recall the command in history. Is there any better terminal that is more user friendly in AIX?
2. AIX is using ksh, instead of Bash. Is there any login shell with a special name that every time you login it can execute automatically, just like the .bash_rc in ubuntu?
3. There's no gedit nor nano nor vim on my AIX, only vi. Is there any text editor that I can download/use without root permission?
