I find it weird that such a convention exists. I would think that a hidden file would be an attribute of the file properties and not of the filename itself. It sounds weird to have to change the filename if you want to unhide it. What if your app is referring to .filename and then someone renames it?
2) With cat there should be no need to use "./" This should really only be used for running executeables in hte current directory. When you cat a file it won;t look in your path.
Ok, why wouldn't the shell search the current directory first for the executable?
Is there some tutorial I can read on this stuff? WHat would I search under.
