Question: 1 / 400

Which command is used to view the current set of environment variables?

set

The command to view the current set of environment variables is 'env'. This command displays a list of all environment variables and their values for the current session, providing a clear view of the configuration and settings that are active in the user's shell environment.

The 'set' command does provide information about shell variables and functions, but it displays not only environment variables but also shell variables, which makes it less focused than 'env' for the purpose of viewing only environment variables. Meanwhile, 'list' and 'show' are not standard commands used for displaying environment variables in Linux. Thus, 'env' is the most suitable choice for this task.
