Compare files in a directory
Hi friends, can anyone help me comparing files in a directory. I have files f1, f2, f3, f4, f5, f6, f7, f8 in a directory each created on a daily basis as f1 on day1, f2 on day2, f3 on day3, f4 on day4, f5 on day5, f6 on day6, f7 on day7, f8 on day8. I need ignore the latest two files (here f7 and f8) from comparison.
I just need to compare files f1, f2, f3, f4, f5, f6 and print the difference. Also can i compare only a set of files say f4, f5, f6 as the file count increases on a daily basis ignoring the latest two files.
Any clue or suggestions would be great.
Thanks in advance!

tiffcmp
TIFFCMP(1) General Commands Manual TIFFCMP(1)
NAME
tiffcmp - compare two TIFF files
SYNOPSIS
tiffcmp [ options ] file1.tif file2.tif
DESCRIPTION
Tiffcmp compares the tags and data in two files created according to the Tagged Image File Format, Revision 6.0. The schemes used for com-
pressing data in each file are immaterial when data are compared-data are compared on a scanline-by-scanline basis after decompression.
Most directory tags are checked; notable exceptions are: GrayResponseCurve, ColorResponseCurve, and ColorMap tags. Data will not be com-
pared if any of the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal. By default, tiffcmp will terminate if it encoun-
ters any difference.
OPTIONS
-l List each byte of image data that differs between the files.
-t Ignore any differences in directory tags.
BUGS
Tags that are not recognized by the library are not compared; they may also generate spurious diagnostics.
The image data of tiled files is not compared, since the TIFFReadScanline() function is used. A error will be reported for tiled files.
The pixel and/or sample number reported in differences may be off in some exotic cases.
