Shell Programming and Scripting

Perderabo,

Is there a way to set IFS only for reading in from inputfile? While I am reading in my lines, I want to do something like this:

for s in `echo $my_var | sed 's/./& /g'; do
blah...
done

But if my IFS is set to "," the above mentioned for-loop doesn't work. As a temporary solution, I unset IFS before the loop and reset IFS to "," after the loop. Is this the only way or is there another way? My way kinda seems dumb... :-p

Thanks.

I think that this will work....

while IFS=, read n1 n2 n3 ; do
