SC2044: find loop wiki suggestion has problem in specific case

[tbsmark86]

Hi! Sorry if this is not the correct place.

The proposed loop for find has a nasty problem try this:

while IFS= read -r -d '' file
do
  (( count++ ))
  cat - > /dev/null
done <   <(find /tmp -print0)
echo "$count"

I've stumbled on this in a real-world example where inside the for loop was some tar and ssh to copy files. Nut sure which process but somebody consumed some of the input leading to strange garbled file names being processed.

A safer solution could be:

while IFS= read -r -d '' file <&3
do
  (( count++ ))
done 3<   <(find /tmp -print0)
echo "$count"

But of course now if some process reads from 3 for whatever reason it's the same problem. Only a bit less likely.
Maybe you could update the wiki?
