The exec command allows the user to execute a text file of CLI commands as if it were typed at a console device.
The exec command and the associated exec files can be used to conveniently execute a number of commands that are always executed together in the same order. For example, an exec command can be used by a user to define a set of commonly used standard command aliases.
The echo command can be used within an exec command file to display messages on screen while the file executes.
