calculate total used disk space by files older than 180 days using find

Question

I am trying to find the total disk space used by files older than 180 days in a particular directory. This is what I\'m using:

    find . -mtime +180 -exec d         


        

Answer 1

Why not this?

find /path/to/search/in -mtime +180 -print0 | du -hc --files0-from - | tail -n 1
