Which command prints environment variables in a Linux terminal?

The command that prints environment variables in a Linux terminal is "env." When executed, this command displays a list of the current environment variables along with their values, which is useful for users to check the environment they are operating in.

It's worth noting that while "printenv" is also a command that prints all or part of the environment, it is often seen as a more specialized tool specifically focused on environment variables rather than all shell variables. The "set" command shows all shell variables, including environment variables, shell functions, and positional parameters, but its output can be bulkier and may include unnecessary details for just checking environment variables. The "showenv" command is not a standard command in most Linux distributions, making it an invalid option when looking to print environment variables.
