user profile script confusion

[Kurt Lieber <debian@kirpatrick.com>]

I'm fairly new to linux in general and am confused about all the different 
login scripts.

I would like to have a single ssh command started when I login, be it to the 
console or to KDE.  If I put the command in .bash_profile, KDE doesn't 
execute it.  If I put it in .xinitrc, then bash won't execute it.  Then 
there's .xsession and .kderc which only add to my confusion.

So, two questions:

1. If I want a command executed whenever (and however) I log in, is there one 
userland file I can put this in? 

2.  Can anyone recommend a site that discusses all the different userland 
login/profile scripts and when to use one over the other to achieve whatever 
result you're trying for?

Thanks.
