The command "glances -c ${hostname}" is used to run the "glances" system monitoring tool with a specific configuration defined by the hostname variable.

Here's a breakdown of the command:

• "glances" is the name of the command or executable file that launches the glances system monitoring tool.
• "-c" is a command line flag or option that specifies the configuration file to use.
• "${hostname}" is a variable or placeholder that represents the hostname of the current machine.

By using this command, the glances tool will be launched, and it will load the configuration file specific to the provided hostname. The configuration file typically contains settings and preferences that dictate how glances will operate, such as what system resources to monitor and how to display the information.
