Kind of like this:
function cmpstat () {
file=$1
declare -A st stx
# Read the stat output
coproc { xfs_io -c "open -P $file" -c "stat -r" | sed -e s/://; }
while read tag val
do
st[$tag]=$val
done <&${COPROC[0]}
wait || exit $?
# Read the statx output
coproc { xfs_io -c "open -P $file" -c "statx" | sed -e s/://; }
while read tag val
do
stx[$tag]=$val
done <&${COPROC[0]}
wait || exit $?
# Compare them
for key in ${!stx[*]}
do
if [ "${stx[$key]}" != "${st[$key]}" ]
then
case $key in
stat.mask|stat.attributes|stat.btime.tv_*)
# Not supported in stat
;;
*)
echo differ $key "${stx[$key]}" != "${st[$key]}"
;;
esac
fi
done
}
cmpstat /
