This command is used in Arch Linux to locally sign a key with GnuPG. Here is an explanation of each part of the command:
-
sudo
is used to execute the command as a superuser or with administrative privileges. It allows the command to perform actions that require elevated privileges. -
pacman-key
is a utility in Arch Linux used to manage the package manager's keyring, which contains trusted keys. -
--lsign-key
is an option that specifies the action to be performed. In this case,--lsign-key
is used to locally sign a key. When a key is signed, it signifies that the signer trusts the associated public key. -
"${select}"
is a variable representing a key ID or fingerprint that is passed as an argument to the command. It is enclosed within double quotes and preceded by a dollar sign and curly braces to expand the variable.
In summary, the command sudo pacman-key --lsign-key "${select}"
is used to locally sign a key with GnuPG in Arch Linux. The key ID or fingerprint is provided as an argument to the command.
