[lug] Changing paths

This problem has has bitten me a couple of times. Each time I have to
the man pages and try and figure out what is happening. After reading a
about the problems discussed here I decided to make a matrix and hold
onto it.
Hopefully the BLUG users will find it usefully too. I just did a quick
of the man pages so if I made mistakes I'm sure everyone will let me

In my understanding there is a difference between "interactive" and
"non-interactive" shells, at least for bash, and what files they source
is to
avoid the problem where a user aliased ls='ls -l' and this will break a
script expecting a standard ls. Similar problems arise with PATH
pointing to an
ls which is unexpected.

Session Type    ksh          bash                 csh          tcsh
------------    ------------ -------------------  ------------
interactive     /etc/profile /etc/profile         /etc/.login 
login           ~/.profile   ~/.bash_profile* or  ~/.cshrc    
                $ENV++       ~/.bash_login*       ~/.login    
                             ~/.profile*                       ~/.cshrc*
interactive     $ENV++       ~/.bashrc            ~/.cshrc    
non-interactive $ENV++       $BASH_ENV++          ~/.cshrc    

* Which ever file it finds first.
++ If this variable exists, and has the correct uid it reads the file
which it
points to.
