gh-extension:tldr:17352

The command "gh extension upgrade ${extension_name}" is used to upgrade a specific GitHub CLI (gh) extension to its latest version.

Here's a breakdown of the command:

• "gh": It is the command-line tool provided by GitHub, used for interacting with the GitHub platform.
• "extension": It is a sub-command of "gh", used to manage and interact with installed extensions.
• "upgrade": It is a command within the "extension" sub-command, used to upgrade an installed extension.
• "${extension_name}": Represents the name of the extension you want to upgrade. You need to replace "${extension_name}" with the actual name of the extension you want to upgrade.

By running this command and specifying the name of the extension, the GitHub CLI will check for any available updates for that particular extension. If an upgrade is available, it will download and install the latest version, bringing your extension up-to-date with the most recent features and bug fixes.
