Description:
 def compare(ctx, commands):
 """ Run 'show | compare' for set commands. @param ctx: The click context paramter, for receiving the object dictionary | being manipulated by other previous functions. Needed by any | function with the @click.pass_context decorator. @type ctx: click.Context @param commands: The Junos set commands that will be put into a candidate | configuration and used to create the 'show | compare' | against the running configuration. much like the commands | parameter for the commit() function, this can be one of | three things: a string containing a single command, a | string containing a comma separated list of commands, or | a string containing a filepath location for a file with | commands on each line. @type commands: str @returns: None. Functions part of click relating to the command group | 'main' do not return anything. Click handles passing context | between the functions and maintaing command order and chaining. """
