I think the tsh is defined in your /etc/passwd file!

The tsh shell also can be invoked by defining it as the login shell in the /etc/passwd file.

Is that the root account you are using? I guess you need to change the login shell using chuser

hi khalidaa,

i think you didn't read my question properly

Well, I think you didn't state your problem properly... ;-)

Which user id?
How did you get stuck?
What did you do?

Khalidaa gave you a hint: the user's login shell is configured in /etc/passwd. Find a way (ask your system admin?) to change the login shell back to /usr/bin/ksh and you should be fine.

Thanks p5wizard for the clarification

I'm sorry rfkhan123 If I couldn't give you the answer you expect. Could you please explain your problem more so i can be of a help?

Like when did that happen? When was your last time to have ksh with no problem? and most important are you using root account?

Khalid

Thanks khalid and p5wizard for taking interest in my problem.

actually, i am practising unix commands on IBM AIX RS/6000 system. while working i pressed ctrl+x ctrl+r key and shutdown the system then when i restarted the system with the root account, it took me into tsh# shell. and from here tsh# shell it is not getting back to korn shell or any other shell. tsh shell is limited and when i was searching on google i found that it allows only 3 commands su, command, shell . i tried all the 3 but they are closing the terminal and when i am restarting the terminal, it's showing me again the same tsh# shell.

please let me know if you understand my question clearly.


Thanks

Ok there should be an easy way out of this!

But if you say that you are using root! then i suggest you boot into maintenance mode using AIX 5.2 CDs and access rootvg with mounting the filesystem and then try to change the root shell using chuser!

There must be an easier way than this but that's what i can think of for now! i will look into this problem tomorrow when i got access to an AIX box!

Try this command from within tsh to reset root's shell to ksh:

chuser -a shell=/usr/bin/ksh root

The three commands you are referring to are normally used to end tsh and get back to ksh or whatever shell you had before. Other commands (as long as they are in the TCB - Trusted Computing Base - a.o. chuser) should work from within tsh also.

If it doesn't work, then you may need to boot in maintenance mode and proceed as Khalid explained.
