mac2unix Command (with examples)

Change the line endings of a file

mac2unix filename

Motivation: This use case is helpful when working with files that have macOS-style line endings and need to be converted to Unix-style line endings for compatibility with other systems.
Explanation: The first argument filename specifies the name of the file that needs its line endings changed. This can be a relative or absolute path.
Example Output: The file specified by filename will have its macOS-style line endings converted to Unix-style line endings.

mac2unix -n filename new_filename

Motivation: This use case is useful when you want to create a copy of a file with Unix-style line endings, while preserving the original file.
Explanation: The -n option instructs mac2unix to create a copy of the file filename with Unix-style line endings. The first argument filename specifies the name of the original file. The second argument new_filename specifies the name of the new file that will be created.
Example Output: A new file named new_filename will be created, which is an exact copy of the original file filename, but with Unix-style line endings. The original file filename remains unchanged.

Remember to replace filename and new_filename with the actual filenames or paths in your command.
