Cut a Variable into sub variables based on a delimiter
Hello All,
I am novice on Shell Scripting. Any help on this is highly appreciated.

I have a variable

$VARIABLE="$some1|$some2|$some3"

I need sub variables $SUBVAR1,$SUBVAR2,$SUBVAR3 which must be equal to $some1 , $some2 and $some3 respectively.

It works fine with

$SUBVAR1 = `echo $VARIABLE | AWK -F"|" '{print $1}'`
$SUBVAR2 = `echo $VARIABLE | AWK -F"|" '{print $2}'`
$SUBVAR3 = `echo $VARIABLE | AWK -F"|" '{print $3}'`

I needed this in a loop.
But I can't give print$i in the AWK.

In future the $VARIABLE may be expanded to $some4|$some5 and in that case I must have two new sub variables $SUBVAR4 and $SUBVAR5.


Any help on this is appreciated.


Thanks
