auracle:tldr:c93ab

This command is used to search the package repository in the Arch User Repository (AUR) using the auracle tool.

auracle is a command-line tool that provides an interface to interact with the AUR.

The specific command auracle search '${regular_expression}' searches for packages in the AUR that match a given regular expression. The regular expression is denoted by ${regular_expression}. You need to replace ${regular_expression} with your actual regular expression.

Regular expressions are patterns used to match and manipulate strings. By using regular expressions, you can search for specific patterns or characters in package names or descriptions in the AUR. The search will return all package names that match the given regular expression.

For example, if you want to search for all packages that have the word "python" in their name or description, you can use the command: auracle search 'python'. This will return a list of all packages in the AUR matching the regular expression 'python'.

Note that auracle needs to be installed on your system to use this command. You can install it using the package manager for your Linux distribution, such as pacman on Arch Linux.
