It is often desirable to change the way a program behaves to better suit your environment. Intercom has many options which can be set by the user. This chapter takes to step by step through these options and helps you tailor Intercom to your specific requirements. We will begin with the most important options and proceed from there to some options which most people won't need to change but are provided in the event you do.
Before we get into the options Intercom has to offer, you will want to save your settings once you have things set up. Intercom reads two files when it starts, a file called intercomrc in SYSCONFDIR (usually /etc or /usr/local/etc) and .intercomrc in the home directory of the user running intercom. This file is simply a list of Intercom commands which get executed on startup. The rc file may have comments denoted by the # character at the beginning of the line.
The save command saves all settings (variables, aliases, and hooks) to the .intercomrc file in your home directory. Any information previously contained therein is erased. save does have a few options which control its behavior, use help save for a usage summary. They are fairly self-explanatory so they will not be discussed here.
