The command gpg --decrypt ${doc-txt-gpg} is used to decrypt a file that has been encrypted using GNU Privacy Guard (GPG).

Here's a breakdown of the command:

• gpg is the command-line tool for encryption and decryption using GPG.
• --decrypt is an option that tells GPG to decrypt the specified file.
• ${doc-txt-gpg} is a placeholder for the filename of the encrypted file. The ${} syntax is often used in Unix-like systems to reference variables.

To use this command, you need to replace ${doc-txt-gpg} with the actual name of the file you want to decrypt, including its path if it's not in the current directory. For example, if the encrypted file is named document.txt.gpg and it's in the current directory, you would run gpg --decrypt document.txt.gpg.
