So either set konsole up to launch ksh as a login shell, or set ENV

The .profile is always gets parsed (both in a login and a non-login
shell).

This is not correct, unless you have a line such as the following in
your .profile:

export ENV=~/.profile

However, your non-login shells will inherit exported variables from
your login shell, so your prompts will still be set, etc. This is the
difference between variables that are exported and not exported.

When I start pdksh in a non-login shell, the .profile gets parsed, and
the PATH and every other env.var. gets set. Only the aliases gets
ignored, but why?

Because you are mistaken... the .profile does not get parsed. The
environment variables are being inherited from the parent shell. if
the .profile was being parsed, your aliases would be there too.


If I add the ENV="~/.kshrc" line to my .profile and my ~/.kshrc contains
my aliases, then I still can not see my aliases...

You need to export ENV. This can be done as I did above, or like
this:

ENV=~/.profile; export ENV

The man says that "if the ENV parameter is set when the shell starts" :)
This is funny because I can set the ENV parameter in a shell, and I can
not set it before running the shell :)

Yes you can... you can export it from a parent shell.

Something must be running already (eg. KDE) to be able to set up the
variable. I can put a file which contains 'ENV="~/.kshrc"' to my
~/.kde/env/ and that gets sourced by kde startup, so the ENV
parameter will be set when I start konsole. Wait a minute... that
is what I'm gonna do! :)

And if you tried that, it didn't work either... because you didn't
export ENV.
