Digital signing a file using a specific key
Since I want to digitally "sign" a file using a specific key, I will run the following command using the PGP key pair called "Maria" which I have been using for digital signing and local testing:
gpg --local-user "Maria" -s inline_signature.txt
And this creates a file called inline_signature.txt.gpg, indicating it is an inline or complete signature.
The --local-user option specifies a user id (or name) to use for signing. In my case, it is "Maria". And that is how I set up the PGP key pair in the article entitled Making and verifying digital signatures using GPG in Linux.
That is what is meant by "Digital signing a file using a specific key".
