man wall

Wall displays the contents of file or, by default, its standard input, on
the terminals of all currently logged in users.

Maybe you can use
wall
that will send a broadcast message to all terminals (shells).

Maybe you have
getent passwd
this works better than finger.

#!/bin/sh
getent passwd |
awk -F: 's[$1]++==0 && s[$3]++==0 {print $1":"$5}'
while read line
do
IFS=":"
set $line
echo "
Hello $2

please log off." |
mail -s logoff $1@mail.usask.ca
done

The awk line eliminates duplicates of fields 1 (ID) and 3 (UID).
