Hi,
when I execute some simple commands on my solaris system, I am getting the following warning message:

Could anybody tell me what could be the reason

Ex:- If I give the command,
which ls
Warning: cannot determine current directory
/usr/bin/ls

Thanks in advance

please post the output from "df -h" or "df -k" maybe the /var filesystem is full....? and what is the output of "pwd"?

The output of df -k is:-

If i give, man ls command,it is displaying error message as
getcwd: Permission denied

If i run the commands from the (/) file system, they are working fine
whereas If i run commands from my directory it is giving the above error messages.

Thanks for ur response

your filesystem is fine.. seems like some rights problem occure....

There is one scenario where this can happen.
You are in a directory. And somebody else might have deleted the directory without your knowledge.

Change to a different directory and try.

yeah, you are right... or a filesystem ist unmountet without your knowledge...
