You would use it like this: <pre>find "$D" | while read f; do stat -c'%n %s %b %f %u %g %D %i %h %t %T %Y %Z %o' "$f"; done | sha1sum | sed 's/[ -]//g'</pre> So instead of the <code>-t</code> option, you must use <code>-c'%n %s %b %f %u %g %D %i %h %t %T %Y %Z %o'</code> which is actually the exact same thing but without the <em>%X</em> format parameter which represents the access timestamp. Using the <code>-c...</code> options you can customize the script in any way you want, in very fine detail. Just see <code>man stat</code> for a reference on the format parameters. Hope this helps! :) Of course! You would use it like this:

find "$D" | while read f; do stat -c'%n %s %b %f %u %g %D %i %h %t %T %Y %Z %o' "$f"; done | sha1sum | sed 's/[ -]//g'

So instead of the -t option, you must use -c'%n %s %b %f %u %g %D %i %h %t %T %Y %Z %o' which is actually the exact same thing but without the %X format parameter which represents the access timestamp.

I am wondering because I need a way to scan a removable hard disk for new/modified files, but am not interested in if they were accessed or not since my app will be accessing the files in normal operation.

Without the backticks the command yields the same result, obviously. [Edit] Removed a useless backtick execution of stat (i.e. echo `stat -c%s $f`).
