Say Temp.txt contains the single line

RandomText

The command

read -r line < Temp.txt

sets $line to "RandomText", but

cat Temp.txt | read -r line

does not. However,

cat Temp.txt | while read -r line ; do echo "$line" ; done

works.

Why are they different? Isn't "read" reading form stdin in all cases?
