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::Default::Plugins::Source(3pm) Perl Programmers Reference Guide CPANPLUS::Shell::Default::Plugins::Source(3pm)NAME
CPANPLUS::Shell::Default::Plugins::Source - read in CPANPLUS commands
SYNOPSIS
CPAN Terminal> /source /tmp/list_of_commands /tmp/more_commands
DESCRIPTION
This is a "CPANPLUS::Shell::Default" plugin that works just like your unix shells source(1) command; it reads in a file that has commands
in it to execute, and then executes them.
A sample file might look like this:
# first, update all the source files
x --update_source
# find all of my modules that are on the CPAN
# test them, and store the error log
a ^KANE$'
t *
p /home/kane/cpan-autotest/log
# and inform us we're good to go
! print "Autotest complete, log stored; please enter your commands!"
Note how empty lines, and lines starting with a '#' are being skipped in the execution.
