The command "gist ${file-txt} ${file2-txt}" refers to a command-line instruction for creating a "gist" on the GitHub Gist platform.

Here is a breakdown of the command:

• "gist": This is the main command that initiates the process of creating a gist.
• "${file-txt}": This is a placeholder indicating that you should replace "${file-txt}" with the name of a text file you want to include in the gist. You should remove the "$" sign and the surrounding curly brackets, replacing them with the actual file name and extension. For example, if your file is called "example.txt", you would replace "${file-txt}" with "example.txt".
• "${file2-txt}": Similar to the previous placeholder, this indicates that you can provide multiple files to be included in the gist. You should replace "${file2-txt}" with the name of another text file you want to include if necessary, following the same parsing rules.

In summary, this command is used to create a gist on GitHub that includes the contents of one or more text files.
