Return IFS to Space

[simpson]

Hello,

I have a (KSH) script taht interprets different input squences and processes them. The first of which is a CSV so I have set IFS to , with:

IFS=,

Now later in my script I am reading input in from a grep command and would liek to |read var1 var2 var3 ....

How do I set my IFS back to spaces. Here is what I have tried thus far:
IFS=
IFS=""
IFS=" "
IFS=''
IFS=' "

Any help would be greatly appreciated.
Mike

Hi

I prefer to do it this way :

oldIFS="$IFS"
IFS=','

read csv

IFS="$oldIFS"

But what you ask for would be :

IFS="`echo ' \n\t'`"

A better way is...

unset IFS

The default field separator is a space.
