After doing some experimentation of my own, I noticed that the access times on files are not always updated when accessed, either through a text editor -- without modifying the file -- or cat.
Although I don't have the server edition of Ubuntu installed, I imagine this would be pretty useful in a server environment, in cases where a breach is suspected.
In particular, I'd like to know which file I need to modify so that the access times on files get automatically updated no matter how many times they're accessed.
