Release Status: release


When a 'read -p "line of text."' built-in is placed inside a while loop which has redirected input to another read built-in, the read command inside the while loop does not execute. I know this sounds vague, but see the example and it will make more sense.



read -p "hello press a key."

while read a b c ; do

 echo $a

 read -p "Looping.. press a key."  <--- This 'read' will not execute.

 echo $b
 echo $c

done < <(ls -al ~/)

exit 0
