gh-gist:tldr:45ed8
This command is using the "gh gist list" command-line tool to list the Gists (code snippets) associated with the authenticated GitHub user.
The "--limit" option allows you to specify the maximum number of Gists to display. In this case, the value of "${42}" is being used as the limit, which suggests that the limit is set to the value of the environment variable "42".
Environment variables are placeholders that can hold values, and they are often used in scripts or commands to make them more flexible. By using "${42}" instead of a specific number, the command can dynamically retrieve the limit value from the environment variable during execution.
So, when this command runs, it will utilize the "gh gist list" tool to retrieve the list of Gists associated with the user, and it will show a maximum of 42 Gists in the output.
