option to remove big line break (-s)
option to add line number to non empty lines (-b)
option to add line numbers to all lines (-n)
option to encrypt the file (-e) (AES-128 bit)
option to decrypt the file (-de) (AES-128 bit)

1- node cat <filepath> => displays content of the file in the terminal 🗄
2- node cat <filepath1 filepath2 filepath3...> => displays content of all files in the terminal in (concatenated form) in the given order. 🗃
3- node cat -s <filepath> => convert big line breaks into a singular line break 📜
4- node cat -n <filepath> => give numbering to all the lines 🔢
5- node cat -b <filepath> => give numbering to non-empty lines 🔢📜
6- node cat -e <filepath> <key> => encrypt file with Military Grade(AES-128) bit encryption 🔒
7- node cat -de <filepath> <key> => decrypt file with Military Grade(AES-128) bit encryption 🔓
8- node cat -c <filepath> => Compresses the text based file using Huffman Coding 🗜
9- node cat -d <filepath> => Decompresses file compressed file 🗄
10- node cat -touch <filepath> => Creates new file/folder at the specified path 🆕
11- node cat -tree <filepath> => Draws the path tree 🌳
12- We can mix and match some of the options.
1- If file entered is not found then it gives file does not exist error.
2- -n and -b are 2 options which are mutually exclusive so if user types both of them together only the first enter option should work.
3- -s and any or both -n and -b present then -s will be executed first and then -n and -b according second rule.
4- Advanced options like encryption/decryption can not be mixed matched.
5- For Encryption and decryption 16 character (128 bit) key is required.
6- Compression is done using Huffman coding.
7- Can only decompress file which is compressed using this software only.
8- Touch command can create new folder or files.
9- filepath in tree command is optional.
