Trying to figure out how the environment variables are being set
I just started a new job and I've been tasked with cleaning up the files that set up all the environment variables. The system works as is. What happens is:
1. You log in to the server.
2. You call a file that sets a bunch of environment variables and that displays a list of all the databases you can connect to.
3. You select the database you want to connect to by calling a file that contains all the environment variables for that specific database (i.e. . filename).

This is all straight forward for some databases, but with others the file name starts with a period. Even though it starts with a period, executing the file with the . filename syntax seems to work fine.

With one database, there is no file under the home directory named after the database, and yet when you execute . filename for that database, you connect just fine.

Anyone have any ideas what is going on? I haven't been able to get any answers at my new job because everyone is so busy. Thank you in advance for any insight you can give.

LKBIB(1)                                                      General Commands Manual                                                     LKBIB(1)

NAME

       lkbib - search bibliographic databases

SYNOPSIS

       lkbib [ -v ] [ -ifields ] [ -pfilename ] [ -tn ] key...

       It is possible to have whitespace between a command line option and its parameter.

DESCRIPTION

       lkbib  searches bibliographic databases for references that contain the keys key... and prints any references found on the standard output.
       lkbib will search any databases given by -p options, and then a default database.  The default database is taken from the REFER environment
       variable  if it is set, otherwise it is /usr/dict/papers/Ind.  For each database filename to be searched, if an index filename.i created by
       indxbib(1) exists, then it will be searched instead; each index can cover multiple databases.

OPTIONS

       -v     Print the version number.

       -pfilename
              Search filename.  Multiple -p options can be used.

       -istring
              When searching files for which no index exists, ignore the contents of fields whose names are in string.

       -tn    Only require the first n characters of keys to be given.  Initially n is 6.

ENVIRONMENT

       REFER  Default database.

FILES

       /usr/dict/papers/Ind  Default database to be used if the REFER environment variable is not set.

       filename.i            Index files.
