Try:


#!/bin/zsh
 
IFS="
"
 
i=1;
for line in `cat file`
do
    x[$i]=$line
    i=`expr $i + 1`
done

There were several solutions, but here is a simple one:

x=( "${(f)$(< file)}" )

lines as array elements

[Jose Unpingco]

hi,

I have  a file that looks like this:

    -503  306 -498  428
    -500  435 -501  588
    -497  440 -501  593
    -505  451 -502  601
    -510  324 -511  454
    -505  328 -511  459
    -506  333 -509  464
    -520  342 -492  463

what I'd like to do is get each line into an array element like

x[1]="-503  306 -498  428"

up to

x[8]="-520  342 -492  463"

I've tried x=(`cat file`) but that splits on the spaces between the
numbers. I've looked at the IFS variable and tried to change it to
newline but that doesn't work as expected.

Thanks.
