Code:
-s : is file test operator. Replace with the test operator you need.
filename : is file name. Replace with your file name.

Code:
if [ -s filename ]
then
      # Perform your action here.
fi

Compiling? Not sure what you are talking about. I think below article will help you:-

If you have the file "TCM_HC_ERR_Report.txt" in the same directory which is the script, it must work, on the other hand...you should declare a variable, for example "file" and to assign to this the name of file. It's better to assign the whole path of file, for example, /home/xxx/xxx/TCM_HC_ERR_Report.txt.

Does the output send any kind of error? SmilieSmilie
