I'm a beginner at shell scripting and I would like to borrow someone's help. I
wrote a little test script which I would like to run nightly. /I cannot figure
out how to erase files only if they are void/. I searched the net to no avail
and how to do this is beyond my knowledge, I'm afraid.
The script is below if anyone is truly curious
#!/bin/bash
cd /home/roy/Main/Programs/Syndication/
