The command "encfs --reverse ${path-to-plain_dir} ${path-to-cipher_dir}" is used to create an encrypted folder using EncFS in reverse mode.

Here's what each part of the command means:

• "encfs": This is the command to invoke the EncFS tool. EncFS is an open-source cryptographic file system that provides encryption and decryption of files on a directory level.
• "--reverse": This flag tells EncFS to work in reverse mode. In reverse mode, instead of creating an encrypted folder and mounting it as a virtual drive, EncFS will create a plain folder that will be automatically encrypted on-the-fly when files are written to it.
• "${path-to-plain_dir}": This is the path to the directory you want to use as the plain directory. This is where you will store your unencrypted files.
• "${path-to-cipher_dir}": This is the path to the directory where the encrypted files will be stored. EncFS will automatically encrypt the files in the plain directory and save them in this directory.

By running this command, EncFS will create the necessary virtual file system and start encrypting any files you add to the plain directory. The encrypted files will be saved in the cipher directory, and you can access them through the plain directory as if they were unencrypted.
