Top Forums Shell Programming and Scripting While read won't run keyboard function Post 303022181 by MadeInGermany on Monday 27th of August 2018 02:28:36 AM

The read in the pause function competes with the read after while.
You can redirect the read to a keyboard device.
Code:
read -p "Press [Enter] key to continue..."  </dev/tty

Or you can redirect the whole function
Code:
pause </dev/tty

A good alternative is to use another descriptor for the while read
Code:
while read ... <&3
do
   ...
done 3< filename

The descriptor 3 does not clash with the standard descriptors 0=stdin, 1=stdout, 2=stderr
