    Ksh version problem under Redhat

    Hello
    I have RHEL 4 (Red Hat Enterprise Linux 4), installed on two machines. On one of this (machine 1), I made an installation "basic", i.e I have not used the extra CD. On the other (machine 2) I used this CD, which I found KSH, so I installed that. But surprise, I found myself with KSH on both (I want), but especially with two different versions of KSH. If I could identify version KSH, AC I would have fewer problems, but this is not the case: In the man ksh, it is clear that KSH set an environment variable, KSH_VERSION. Now on the machine 2, this variable is not present when I am in ksh. Is there a way to know what is the shell used in a given terminal? Any help on this is appreciated. Thanks in advance.

    Hello,
    I think you have not installed the korn shell properly during the installation, that is why you are getting such an error, with a little luck, ksh is installed via an rpm
    Here is the command to install it, if you have not installed it properly then you can try installing again
    Code:
    rpm-qa | grep ksh
    Here you have to issue this command in the terminal as a root user.

    Hello,
    This is what you should get when you do the man command in the terminal. The man may be for ksh (RHE3):

    Code:
    VERSION
    This page documents version
    @ (#) PD KSH v5.4.14 8/04/14.2
    public domain korn shell.
    Just type the man command in your terminal and see what is the result you are getting.

    Hello
    It gives something:
    Machine 1:
    Code:
    pdksh-5.2.14-30
    Machine 2:
    Code:
    ksh-20040229-12
    good as the first seems to be a correct result, which gives something usable, but the second ... Well I do not understand what it says. Can you please explain me, why the second is not showing the correct result.

    Hello,
    Just try the following commands
    Code:
    Which ksh
    followed by
    Code:
    ls-al [will display all]
    Sometimes a facility would have simply made a glib link (symbolic, it is more visible) on sh ksh or bash). Hope the following information will help you. If yo have any other problem then do post back.
