tlmgr-repository:tldr:90896

This command is used to add a new repository to the TeX Live Manager (tlmgr) tool, which is a package manager for TeX Live, a popular typesetting system used for creating documents with high-quality typography.

Here is an explanation of each part of the command:

• sudo: This is a command that allows the user to execute a command with superuser (root) privileges. It is commonly used in Unix-like operating systems to perform administrative tasks.

• tlmgr: This is the main command for the TeX Live Manager. It is responsible for managing packages, updating the TeX Live system, and performing other package-related tasks.

• repository: This is an option that specifies the action we want to perform with the tlmgr command. In this case, we want to add a new repository.

• add: This is another option that specifies the specific subcommand we want to execute. With the repository option, the add subcommand is used to add a new repository.

• ${select}: This is a placeholder or variable that represents the URL or path of the repository we want to add. The actual value for this variable should be provided when executing the command.

• ${tag}: This is another placeholder or variable that represents a tag or identifier for the repository. This is also a variable that should be replaced with a specific value when executing the command.

To use this command, you would need to replace ${select} with the actual URL or path of the repository you want to add, and ${tag} with a suitable identifier for the repository.
