UNIX Basics about shell and editors and default settings
Hi all,
I have 3-4 years of experience working on unix environment. I am not a beginner, but unix is not my primary skill set. I am very good at awk programming and doing many of my tasks very well, really very weak on basics. I moved to a new job recently and the settings there are driving me nuts. Following are my questions:

1) Who decides what shell would be default when we login to unix enviroment? Is there any way we can overide it?

2) I am currently using korn shell and i was using the same shell in my old job, but i am not able to mimic mostly of the usual commands and functionality at my new environment. The things that are driving me nuts is :

- not able to use arrows on command line , gives me garbage
- escape \ to get the command history
- autocomplete the filenames
- when i use the vi editor, it does even tell me which mode i am in, when i press insert it changes the case of the text
- not able to use page up and page down to scroll through scripts

Many other things. they are very basic but i am so used to all these settings , it is literally driving me nuts. Can someone help me what settings need to be done?

Also some one can point to some books/documentation to understand the basics about shells and the settings and different editors how and when to use it would really help me a lot ! Thanks in advance .

What operating system were you using before? What operating system are you using now? What output do you get from the command?:
Code:
uname -a

How is the TERM environment variable set? What locale are you using? What are you using as a terminal or terminal emulator when logging in to your current system? What output do you get from the command?:
Code:
env

What shell settings are you using in the Korn shell? What output do you get from the command?:
Code:
set -o

If you can show us the output from the above requested command on your current system, it will help. If you can also show us the output from the above commands on your previous system, it will help us see things that are different between the two systems.

Your default shell when you login is defined in: /etc/passwd
Are you sure its the same?
Code:
ksh --version

Interactive features like braceexpand and histexpand only exist in pdksh (optional on Linux) and ksh93 (Solaris 11).
But you have got ksh88 on Solaris 10.
Regarding command history, get comfortable with the fc command! (I never did.)
Code:
man fc

Alternatively you can try bash on Solaris 10.

You can also do "which bash". I supported Solaris. The person who I worked with really wanted to use tcsh, and I would rather use bash. So every time I connected to a server, I needed to type bash to get the bash shell. Then I could maintain a .bashrc file to set preferences the way that I wanted them to be. This should work for you as well. There are plenty of sample .bashrc files on the web.
