Application to encode or decode data using Caesar cipher via command line.

Caesar cipher CLI

My implementaion of the task.

To run the code open any command line and run one of the examples below.

Here are some options:

• -a or --action should be equal to encode or decode, it is a required option;
• -s or --shift should be a not negative integer, it is a required option;
• -i or --input should be a string, it is a relative or an absolete path to the input file. If the file is not found, the message will be shown. If the option will not be provided, you will be offered to enter some text in a command line.
• -o or --output should be a string, it is a relative or an absolete path to the output file. If the file is not found, the message will be shown. If the option will not be provided, the output will be performed to the command line.

Examples:

node cli.js -s 7 -o output.txt --action encode -i input.txt

or

node cli.js --shift 7 --output "./output.txt" --action encode --input "./input.txt"
