What command is used to display the current date and time?

The command used to display the current date and time in a Linux environment is "date." When this command is executed in the terminal, it retrieves the system's date and time settings and presents them in a human-readable format. This command can also be modified with various options to display the date and time in different formats or to perform various operations related to date and time.

For instance, simply running the command without any options will yield the current date and time in the default format. Additionally, the "date" command can be used to set the system date and time when executed with the appropriate privileges and options, making it a versatile tool for managing time settings in Linux.
