Create a C$-$Shell script program that will read environment variable from a $$environment$.$cfg$$ which contains the values of three environment variables as shown below:

enVar$1$Create a C$-$Shell script program that will read environment variable from a $$environment$.$cfg$$ which contains the values of three environment variables as shown below:

enVar$1$

enVar$2$

enVar$3$

In your script program, please do the following:

Put $$#$!/$bin$/$csh$$ in the first line $($interpreter line$)$ of the program.

Check to see if the environment.cfg file exists if it does not display an error to the user, and exit the program.

Create a loop to read from the environment.cfg$,$ and place each of the lines read into an array element.

Create a switch statement within the loop where each case will check what was read from the array in the respective iteration.

Within each case, set the environment variable based on the value in the array element that was read from the configuration file.

Once the loop has completed, create another loop to echo only the environment variable name, and display to the screen as well as displaying to an output file named $$outputFile$.$txt$.$

After the final loop has completed, exit the script.
