smartctl:tldr:b8f9a

This command is used to initiate a short self-test on a specific hard drive using the "smartctl" utility, with elevated privileges granted by "sudo".

• "sudo" is a command used in Linux and Unix-like systems to execute a command with administrative privileges. It allows users to perform actions as the "superuser" or "root" user.
• "smartctl" is a command-line utility used to monitor and perform various operations on storage devices that support Self-Monitoring, Analysis, and Reporting Technology (SMART). It provides information about the health, attributes, and status of the drives.
• "--test short" is an argument passed to "smartctl" to specify the type of self-test to be performed. In this case, a short self-test is chosen, which examines only a subset of the drive's surface.
• "${-dev-sdX}" is a placeholder indicating the drive on which the test should be performed. Replace "X" with the appropriate letter or number based on the specific drive you want to test (e.g. "sda", "sdb", etc.).

Overall, this command runs a short self-test on a specified hard drive using the "smartctl" utility with administrative privileges via "sudo".
