I can tell you that in ksh there are some minor differences between Sun and HP-UX.
On Sun you will have no problem doing:
but on HP-UX you will have to put double quotes around $VAR.
Also when doing a string comparison, on Sun you can do
but on HP-UX, you can't have the double equals.
There are probably more, but those are a couple I can think of off the top of my head.
if you stick to having double quotes around variables and using only 1 "=" sign for shell tests, you will not notice any difference on the shell scripts aside from the OS-specific external commands ... if you want a portable script that does the same thing on different platforms, have the script check for the OS and then put in the OS-specific command lines as required ...

CPANPLUS::Shell(3pm) Perl Programmers Reference Guide CPANPLUS::Shell(3pm)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
This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
shell.
Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
loading class), so please consult the documentation of your shell of choice.
