This utility verifies the integrity of all files stored in disks of
all pools. For each file, it compares the checksum as computed by the 
individual pool, and the checksum as stored in PNFS. In result, OK or
BAD is appended depending on whether these checksums match.

It performs an exhaustive run (on all files), thus, a site may prefer 
to collect the results in a logfile. E.g.,

osg_dc_compare_checksum_disk_pnfs_for_all_files | tee allfiles.txt \
  | tee | grep BAD | sort > badfiles.log

No Arguments needed.
