In Unix, what startup and termination files do the various shells use?
Although not a comprehensive list, the following should provide you with a basic understanding of what startup and shutdown files the various Unix shells use.
Note: This information comes from the Unix
FAQ, which is posted regularly to the Usenet
newsgroups comp.unix.questions and
comp.unix.shell. You can obtain it by FTP from
rtfm.mit.edu in the /pub/usenet directory,
and on the web at:
