Hi,
which ways exists to redirect the value of (local) variable in while
loop to a global variable?
#!/bin/ksh
VAR=3D1 # global variable
echo "word1 word2" | tr " " "\n" | while read NAME
do
set -a
echo $NAME
VAR=3D2 # this seems to be a local variable within the while loop
done
echo $VAR # this prints out a "1" instead of a "2"
#EOF
Regards,
Andreas
