I don't think so.... QSH (Qshell) is 100% OS400 supported EMULATION of a unix environment. All the tools delivered in QSH are compiled as OS400 objects, whereas PASE is an AIX runtime that has been ported to run under OS400.
Like any emulation, QSH may not perform as well as it seems it should....

Subject: QShell vs. PASE vs. QP2TERM
Hi all,
In my efforts to get my 'sed' script to run fast I thought I would open a
PASE terminal session using CALL QP2TERM which brings up a different shell
than STRQSH, and SURPRISE! - the sed script ran at the speed I was
expecting.
So here's my question: Are there _two_ separate pseudo *nix environments on
the iSeries? Using STRQSH (or QSH CMD(.) from RPG) my results were VERY
slow. Doing the EXACT same sed statement in CALL QP2TERM session was 1/10th
the time of execution, which is the amount of time I was expecting.
For an immediate fix to my needs I am looking to use Qp2RunPase from my RPG
to run the sed command. But I still have a nagging question in my mind as
to how everything on the *nix side relates to each other. From the
infocenter I found this sentence that sort of gives an idea to the overall
infrastructure, but not entirely:
" OS/400 PASE also includes the Korn, Bourne, and C shells and nearly 200
utilities that provide a powerful scripting environment." -

As I understand it, Korn=QP2TERM and C Shells=QShell, is that right?
TIA,
