Split a string in ksh

Question

I am looking for a quick/easy way to split a string in ksh.

It has varied number delimeters (spaces) between each item.

example:

value1 value2                  value3

Any suggestions/advice?

Answer 1

Using a for loop with the input string will split on whitespace.

LIST="value1  value2 value3"
for x in $LIST ; do
    echo $x
done

Yields

value1
value2
value3

or

LIST="value1  value2 value3"
set -A STRING "$LIST"
for x in $STRING ; do
    echo $x
done

Yields

value1
value2
value3

Answer 2

You can use an array.

LIST="value1  value2 value3"
set -A values $LIST
echo ${values[0]}

value1
