Then use a better command:

ls /dev/rdsk/*

>And print the PV id for this device files using the below script

for disk in $(ls /dev/rdsk/*); do

   xd -j8200 -N16 -tx $disk

Yes, you can get that with:

ll /dev/rdsk/*

Or use: find /dev/rdsk -mtime -N

Or use: find /dev/rdsk -newer reference-file

Just pipe to grep:

grep -v -e "^00000010" -e "       0               0               0               0"

(Assuming I counted the spaces correctly.)
