Re: Where is a good reference for setting PATH in all the various shells

Let me suggest that you read the man page entries for the various shells
you are interested in working with.  For example, the man page for bash
states:

       When  bash is invoked as an interactive login shell, or as a
non-interactive shell with the --login option, it first reads and
executes  commands  from  the file /etc/profile, if that file exists. 
After reading that file, it looks for ~/.bash_profile, ~/.bash_login,
and ~/.profile, in  that order, and reads and executes commands from the
first one that exists and is readable.  The --noprofile option may be 
used  when  the shell is started to inhibit this behavior.
