Wow,
I realized from your questions that I really did not provide much detail. Thanks for attempting to decipher.

Once the script identifies that there is a duplicate file residing on the /data1 partition I would like to then pass a rm argument to remove the file from /data2 cleaning up space on that partition.


Quote:
Also, is there a directory hierarchy or is there just /data1 and /data2 with no subdirectories?
Yes there is a hierarchy involved. Here is a snippet of it for you. Each partition has a 4 to 6 letter subdirectory that is mirrored on each partition. Files in that structure could be the same.

Code:
/data1/wcnn/*.mp3
/data1/wxxr/*.mp3
/data1/trrn/*.mp3

/data2/wcnn/*.mp3
/data2/wxxr/*.mp3
/data2/trrn/*.mp3

So there may be the same mp3 file in the station abbreviation on /data1 and /data2. I only need that file in one partition.

If I can provide any output commands please let me know.

Jaysunn

fmemcmp

fmemcmp(3)						     Library Functions Manual							fmemcmp(3)

NAME

       fmemcmp - fuzzy comparison of two memory areas

SYNOPSIS

       #include <fstrcmp.h>
       #define FSTRCMP_IDENTICAL
       #define FSTRCMP_THRESHOLD
       #define FSTRCMP_ERROR
       double fmemcmp(const void *data1, size_t size1, const void *data2, size_t size2);

DESCRIPTION

       The fmemcmp() function compares the two memory areas, the size1 bytes pointed to by data1 and the size2 bytes pointed to by data2.

RETURN VALUE

       The  fmemcmp  function returns a floating point value between 0.0 and FSTRCMP_IDENTICAL.  A value of 0.0 means the memory areas are utterly
       un-alike.  A value of FSTRCMP_IDENTICAL means the memory areas are identical.  A value of more than FSTRCMP_THRESHOLD (it lies between  0.0
       and FSTRCMP_IDENTICAL) would be considered "similar" by most people.

       A value of FSTRCMP_ERROR (always negative) indicates a malloc(3) failure.
