# Discard find's stderr, since SELinux or others may prevent us from parsing

# grep's -s suppresses errors about files that vanished before they could be
# read.  It isn't entirely portable, but GNU grep should be a given on Linux.
# Sadly awk has no such equivalent option or we could skip grep altogether.
