You have been getting our help writing scripts for six and a half years. What have you tried to solve this problem on your own?
What two files do you want to create?
What two environment variables do you want to create? What is the rest of your script going to do with these environment variables? If your goal is to split one file into two files and add two variables to your environment. It is easy to do, but adding variables to the environment is a waste of time. As soon as your script exits, anything that your script added to the environment will disappear because environment variables created in a child process DO NOT magically appear in the environment of any parent processes; they only appear in the shell execution environment of your shell script and in the environment of children created by your script and its descendants.

envdir
envdir(8) System Manager's Manual envdir(8)
NAME
envdir - runs another program with environment modified according to files in a specified directory.
SYNOPSIS
envdir d child
DESCRIPTION
d is a single argument. child consists of one or more arguments.
envdir sets various environment variables as specified by files in the directory named d. It then runs child.
If d contains a file named s whose first line is t, envdir removes an environment variable named s if one exists, and then adds an environ-
ment variable named s with value t. The name s must not contain =. Spaces and tabs at the end of t are removed. Nulls in t are changed to
newlines in the environment variable.
If the file s is completely empty (0 bytes long), envdir removes an environment variable named s if one exists, without adding a new vari-
able.
EXIT CODES
envdir exits 111 if it has trouble reading d, if it runs out of memory for environment variables, or if it cannot run child. Otherwise its
exit code is the same as that of child.
