I would assume, althought not completely sure, that bash is compatible with ksh ( only in this direction, not the other way ).

What will be most likely the problem is the usage of external programs. Since HP-UX is a lot different to the linux environment, there could be a lot of change required, especially these kinds:

Some path names are different, hardcoded path names for programs will probably have to be changed
External commands have to partially be changed
invocation of commands with their options and switches are different and have to be adapted

The question to me is, if this is a onetime process or an extension, so that the scripts will run on both platforms in future. For the latter more work is required, to implement some kind of portability layer into all scripts.

Regarding automation, there is nothing I know of. I doubt that there is much regarding the fact that the issue is not to convert ksh syntax but a lot of external program calls, which is no question of converting one defined set of programming language syntax into another(like converting a perl script into c-code, which is possible and where converters exist), but a lot of arbitrary, non-standardized, redundant, ad-hoc code.

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;

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.
