The command atool --each --extract ${*-zip *-rar} is used to extract multiple files with different formats using the atool command-line tool.

Here is a breakdown of the command:

• atool: It refers to the atool command-line tool which is used for file compression and extraction. It supports various archive formats.

• --each: It is an option used to perform the specified action on each file individually. In this case, it will extract each file individually.

• --extract: It is an option used to specify that the action to be performed is extraction. It tells atool to extract the files.

• ${*-zip *-rar}: This is a shell expansion syntax that is used to expand to a list of filenames matching the patterns *-zip and *-rar.

  • *-zip: This pattern matches any file ending with .zip.
  • *-rar: This pattern matches any file ending with .rar.

  The ${*} part is used to refer to all the command-line arguments passed to the script or command. So, ${*-zip *-rar} will expand to a list of filenames that end with .zip or .rar based on the files present in the current working directory or the arguments passed.

Overall, the command atool --each --extract ${*-zip *-rar} will extract each file individually from the arguments that end with .zip or .rar using the atool command-line tool.
