The command "gpg --clearsign ${doc-txt}" is a command-line instruction that uses the GNU Privacy Guard (GPG) tool to digitally sign a plain text document.

Here is a breakdown of the command components:

• "gpg" is the command used to invoke the GNU Privacy Guard tool.
• "--clearsign" is an option that specifies the type of signing operation. When using this option, GPG creates a detached signature that is embedded within the document itself.
• "${doc-txt}" represents the variable for the document's filename or path. It is expected that the user will replace "${doc-txt}" with the actual name or path of the plain text document they want to sign.

So, when executing this command with an appropriate document path or filename, GPG will generate a digitally signed version of the document, where the signature is embedded in the document itself.
