`cpio` has three operating modes, each corresponding to a different function:

1. **copy-out mode** - Create a backup (archive). You can enable this mode through the `-o` or `--create` options. In this mode, you must generate a list of files with a specific command (`find`, `ls` or `cat`) and pass it to cpio.

* `find` : browses a tree, recursive or not;
* `ls` : lists a directory, recursive or not;
* `cat` : reads a file containing the trees or files to be saved.

2. **copy-in mode** – extracts files from an archive. You can enable this mode through the `-i` option.
3. **copy-pass mode** – copies files from one directory to another. You can enable this mode through the `-p` or `--pass-through` options.

Like the `tar` command, users need to pay attention to how the file list is saved (**absolute path** or **relative path**) when creating an archive.
