Re: shell tricks (Re: bash if file exists)

 Just as a quick question and i'm not trying to be a dick about it, but if 
you have a major file system corruption, why would the ability to know what 
files are there be important. I really do ask this question in earnest, and 
more to the point even, if the file system is hosed, and you can still 
though the luck of the gods read the inode table how would the actual files 
themselves not be corrupted. I mean, i'm kinda assuming that you picked this 
info up because you had to, i'm just wondering about the circumstances.
