UNIX for Dummies Questions & Answers

Dear guys,
I don't know the response of a for loop in this situation:
suppose that file1 is an empty file.

and i make a for loop as :
for i in `cat file1`

What will be the response of the for loop:
1- will an error message apear
2- or the for loop simply will not run,and it will escape the for loop to the next step in the script?

i know that I can try it myself but the problem is that I can't log to my system for 5 days as i am on vacation.
thanks for your usual support.

Marwan,
In this case, if you have an empty file, nothing inside of the
'for' command will be executed.

thanks Shell_Life for your fast reply
