No, that will not work in a generic Bourne shell. Generic Bourne shells don't even have math, you have to use the expr external.

The latter is what should be used for a generic bourne shell, yes. Or something like

Code:
I=1
while [ $I -le 3 ]
do
        I=`expr $I + 1`
done

NAME
CPANPLUS::Shell - base class for CPANPLUS shells SYNOPSIS
use CPANPLUS::Shell; # load the shell indicated by your # config -- defaults to # CPANPLUS::Shell::Default use CPANPLUS::Shell qw[Classic] # load CPANPLUS::Shell::Classic; my $ui = CPANPLUS::Shell->new(); my $name = $ui->which; # Find out what shell you loaded $ui->shell; # run the ui shell DESCRIPTION
