ksh93 not reading $HOME/.profile!!!

Max_4 — Sun, 21 Mar 2004 09:29:10 GMT

Hi folks!

I am kind of frustrated with this... I just downloaded and installed
the rpm for ksh93 from this link:
http://rpmfind.net//linux/RPM/contrib/libc6/i386/ksh93-2000.10.31.0-1.i386.html

I am running under Red Hat 8.0. and KDE. The thing is that I created a
user
#useradd -s /bin/ksh student

and I created under ~student:

.profile
VISUAL=emacs
export VISUAL

then I logged out and logged back in as user 'student'
and did:

$set | grep VI

and NOTHING was displayed!!!!!

The curious thing is that it works when I do as 'student':

$su - student
...
$set | grep VI
VISUAL=emacs

WHY could this be happening!!! What else do I need to make it work?

Thank you very much in advance!

Max

Now I think ksh93 is indeed reading .profile, the problem was that the terminal was forking a normal subshell not a
login shell.

I haven't found yet the way of how to fix this for gnome. But I tried
adding --ls to the options for starting 'konsole' and it worked!

What still bothers me is WHY when I log in graphically gdm doesn't
start a login shell like IT SHOULD. I mean when I log in graphically
gdm should know which my login shell is, and read my .profile at that
very first time, so that when I start any subshell I will have my
.profile env variables already set.

The curious thing is that it does indeed read .bash_profile when
logging in graphically, when the login shell is bash not ksh!

I wonder if there's something I can set to make it work correctly.?

Thanks a lot in advance,

Max

Red Hat usually defaults to the .bash_profile

Please check /etc/passwd for the users shell and that file. This may explain any unusual behavior.

Max,

Well, terminals shouldn't be reading .profile when started by gdm and it "is the way of things". If bash does do it for you, it needs a slap on the wrist.

When you get Gnome up, it has arrived courtesy of your login shell, starting a new terminal is starting a sub-shell and hence, no .profile.

A way around this is to edit the xresources file for which ever terminal you use and specify that it should default to a "login" shell in there.

Mark thanks for the input. As a matter of fact, I agree with you regarding a subshell (subshells do not read .profile).

But GDM, I mean the initial graphical login screen, *should* read .profile if your login shell is /bin/ksh. As I said in the case of having a user with login shell bash, GDM does read .bash_profile at login time. Of course when you fork a terminal it does only read .bashrc, as one would expect it to be.

The situation is quite different when the user's login shell is /bin/ksh. GDM _initial login_ screen does not read .profile NOT even once. I think this is wrong because at initial login time (not subshells) ksh should read .profile.

The issue doesn't have to do with terminals reading .profile, for that _one can add_ --ls in the command that creates the terminal, for example to force it to read .profile or .bash_profile/.profile anytime I span a subshell via a terminal. But this is not good. The issue has to do with the Initial GDM login, that doesn't want to read .profile in case of /bin/ksh.

I don't know, possibly I have to change something in gdm.conf, but I don't know.

Thanks!

Hello Manuel,

I guess there is room for disagreement here but I still think bash is wrong. I don't think a GUI should read through .profile by default. Many people have interactive commands in their .profile which can cause lots of nasty things to happen if a GUI is running it. On HPUX the GUI allows you to specifically set wether to read .profile or not and this, for me, is borderline usage :)

However, on a linux box I guess the distinction is not so clear.

However, if you want to achieve this thing, why not just find your system wide Xsession file (which I assume GDM runs) and get it to source $HOME/.profile in there with ". $HOME/.profile". This is the beauty of unix.
