You can create an array. The basic way to create it is:

Code:
set -A ARRAYNAME $(some process with linewise output)

Run the following to get a feeling for this. I suggest you read the man page of "ksh" carefully about arrays to see what can be done using these:

Code:
set -A filelist $(ls)         # put every line of "ls" output into an array element
typeset index=0

while [ $index -le ${#filelist[*]} ] ; do   # ${#var[*]} means: number of elements in array "var"
     echo "Element number $index contains: ${filelist[$index]}"
     (( index += 1 ))
done

The other usual shell method is to work in a loop on one item after the other, being fed into the loop with a pipeline. The above using such a loop:

Code:
typeset -i index=0
ls | while read filename ; do           # set "filename" to one filename after the other
     echo "File number $index is: $filename"
     (( index += 1 ))
done

I hope this helps.
