Yeah, great!

I'm almost done.

The remaining problem is that this date is on the same line with a lot of other stuff and when I launch your command, the whole line is retrieved.
I obtain only the date with
Code:
strings binaryFile | grep -E "Sep" | awk '{ print $21 }'

because there are only strings, separated by blanks or tabs.

But I have a lot of those file to parse...what if this date is not always at position 21?

Is there a way to generalize it?

SYNOPSIS

       string xdiff_string_bdiff (string  $old_data, string  $new_data)

       Resulting patch can be later applied using xdiff_string_bpatch(3)/xdiff_file_bpatch(3).

	For more details about differences between algorithm used please check libxdiff website.

PARAMETERS

	      o $old_data
		- First string with binary data. It acts as "old" data.

	      o $new_data
		- Second string with binary data. It acts as "new" data.

RETURN VALUES

	Returns string with binary diff containing differences between "old" and "new" data or FALSE if an internal error occurred.

SEE ALSO

       xdiff_string_bpatch(3).
