margarit,

The word cat is used as an abbrevaition for concatenate.  The result would be printed.  If there is more than one "input" then they are combined and that result is printed.

The line you have seems to start have  the start of a "here-doc" so it is hard to tell what the result would be.  If this doesn't seem to fit what you are getting or using then please provide more of a sample of the code and clarify what runs it (i.e. the language used).

Let me know if you have any questions or need more information.
