The command direnv deny ${-} is used to deny loading a .envrc file in the current shell session using direnv.

Here's a breakdown of the command:

• direnv is a tool used for managing environment variables in various shell environments.
• deny is a command in direnv that denies loading a .envrc file.

• ${-} is a special shell variable that expands to the current shell's option flags (or "flags" for short). These flags determine the behavior and settings of the shell.

  For example, if the current shell session has the -i flag (interactive mode) enabled, ${-} would expand to -i.

So when the command direnv deny ${-} is executed, it instructs direnv to deny loading the .envrc file based on the current shell's flags. This can be useful in scenarios where you want to prevent the loading of certain environment configurations temporarily.
