Well, "read line" reads from stdin, not "the terminal". And stdin is the
yesabuse.txt file.
Attach yesabuse.txt to a different file descriptor and leave stdin
alone:
while read line <&3
do
...
done 3<yesabuse.txt
File descriptors 0, 1 and 2 are stdin, stdout, stderr. The others are
generally available for use.
Don't forget you can close a file descriptor like this:
exec 3<&-
but for this example it is unnecessary - like all other commands, the
3<yesabuse.txt is opened for the while loop and closed afterwards, just
as it would be for this:
some-command-the-expects-fd-3 3<yesabuse.txt
