reading values into an array
I have this portion of a script and it works:
Code:
base_config="A  B  C  D  E"

for field in $base_config
do
	var[$i]=`echo $field`
             ((i=$i+1))
done

I get an array of var[1]=A, var[2]=B, and so on.

What if I have this example with white space and want to put it into an array while ignoring the white space in the string?
Code:
i=0

base_config="Ex1 255.255.0.0 ab100001 10.2.1.1 \
             Ex2 255.255.0.0 cd200001 10.21.2.1"

for field in $base_config
do
	var[$i]=`echo $field`
            ((i=$i+1))
done

And I want var[1]=Ex1 255.255.0.0 ab100001 10.2.1.1
var[2]=Ex2 255.255.0.0 cd200001 10.21.2.1
and so on.

I want to ignore the white space in the strings and place them into an array.


thanks.

With ksh93, zsh and bash you can write something like this:

Code:
base_config=(
  "Ex1 255.255.0.0 ab100001 10.2.1.1"
  "Ex2 255.255.0.0 cd200001 10.21.2.1"
  )

And it's all done:

Code:
% printf "%s\n" "${base_config[1]}"
Ex1 255.255.0.0 ab100001 10.2.1.1
% printf "%s\n" "${base_config[2]}"
Ex2 255.255.0.0 cd200001 10.21.2.1
