Re: [PLUG] UNIX File Equivalence

=> Here is a good general UNIX question that somebody might know the answer
=> to.
=> On UNIX, or at least on Linux, how can I determine if two files are
=> the same, preferably very quickly (ie via a system/library call and
=> not a page of PERL - though I'd still be interested in scripting/bash
=> solutions as well).

   In C, check out the stat() family of system calls. It returns a "struct
stat", and if the st_dev and st_ino values are the same, the file is
the same.
