Final answer:

The command to print a previously executed command list is the 'history' command, relevant to computer terminals or command line interfaces.

Step-by-step explanation:

The command that will print a list of the commands that you've previously executed in a shell is the history command. When you type history into your terminal or command line interface, it retrieves a list of the commands you have entered in the past for the current session or from a history file where these are stored. This can be extremely helpful for recalling past commands, repeating them, or correcting errors in previous command sequences.

Other options like list, eval, and exec do not serve this particular function. The list command typically does not exist in UNIX/Linux shells, eval is used to evaluate a given string as a command, and exec is used to execute a command and replace the current shell process without creating a new one. The history command is a powerful tool in command-line interfaces, allowing users to review and access a chronological list of previously executed commands. By typing 'history' and pressing Enter, users can see a numbered list of commands along with their execution sequence. This feature aids in command recall, facilitating efficiency and reducing the need for repetitive typing. Users can re-execute commands by referencing their corresponding numbers, leveraging a seamless workflow. This command is particularly valuable for troubleshooting, script development, and maintaining an organized record of command-line activities, enhancing overall productivity and command-line management.
