As the path was guaranteed to start on column 40, I think cut is the 
simplest, fastest, and most "correct" solution .  However, as we're 
still talking about it today however, I offer a couple more regex based 
solutions:

       # this anchors the match to the beginning, and removes the
       # first 39 characters.
     $ perl -pe "s/^.{39}//" < filename.txt

       # Rather than blanket removing the first 39 characters,
       # this matches for removal the 19+ characters of the date
       # and time, and the 20+ characters of the size.  Given the
       # column alignment, I assume this would _not_ be necessary
       # unless you have files larger than 10 TB.  Hmm.
     $ perl -pe "s/^\S{10}\s+\S{5} .M\s+\d\S+ //" < filename.txt

Cheers,
