This project is a command-line tool that executes various commands similar to the cat command but with additional functionalities such as line numbering, filtering empty lines, and converting multiple lines into single lines.

• Line numbering (-n): Adds numbers to each line of the specified file(s).
• Non-empty line numbering (-b): Adds numbers to each non-empty line of the specified file(s).
• Single line conversion (-s): Converts multiple lines into a single line.
• Multiple Commands(e.g., -n -s): Multiple commands could be applied together except for -n and -b as their operations clash.

• -n: Line numbering.
• -b: Non-empty line numbering.
• -s: Single line conversion.

• Line numbering: w-c-at -n filename1 filename2 filename3 ...
• Non-empty line numbering: w-c-at -b filename1 filename2 filename3 ...
• Single line conversion: w-c-at -s filename1 filename2 filename3 ...

• >: Writes output of commands to a file.

  • Example: w-c-at -n filename1 > filename2

• >>: Appends output of commands to a file.

  • Example: w-c-at -n filename1 >> filename2
