I am attempting to turn a ksh variable into an array and then back
into the variable after manipulation. Here is what I have:
==== Cut here ====
#! /bin/ksh
# Now convert this into an array
IFS=":" ; export IFS
set -A tbl $PATH
size=${#tbl[*]}
i=0
while [ $i -lt $size ] ; do
echo "Table element $i is ${tbl[$i]}"
((i+=1))
done
lst="${tbl[*]}"
lst2="${tbl[@]}"
echo $lst
echo $lst2
exit 0
=== Cut Here ===
The problem is that I cannot figure out how to get the colons back into
the PATH. What I want to be able to do is to null out entries all together,
so they are not even present. What I would REALLY like to do is to
have something like an array 'shift' type mechanism I think!
