• The "f" option signifies that the next argument is the name of the archive file.

For instance, the "zip" command is commonly used to create and modify zip files, not to extract contents from .tar.gz files. Meanwhile, "gunzip" can be used to decompress files that are solely gzip compressed (without the tar functionality); using it on a .tar.gz file would remove the gzip compression layer but leave you without the ability to handle the tar archive itself. Lastly, the "
