PASE, an acronym for Portable Application Solutions Environment, is an IBM-supplied licensed program which provides a subset of AIX functionality on the iSeries.

This can be used to port a number of traditionally unix-only capabilites to the iSeries, including zip/unzip, sftp, tcl and GnuPGP.

When released as part of V4R4, V4R5 and V5R1, PASE was a chargeable LPP. As of V5R2 and later, it has become a no-charge option.

PASE is installed as option 33 of the OS/400 LPP. On V5R3 it is 5722SS1, Option 33.

In addition to traditional *ux-style utilities, PASE can support various open source software like Perl. Often, the AIX version of a package can be used as-is in PASE. Sometimes you'll need RPM; see PASE_Open_Source. Perl itself can be installed via 5799-PTL (IBM Tools for Developers for IBM i).

Shells

PASE includes three shells: Korn (ksh), Bourne (bsh), and C (csh). The default shell, located in the IFS at /QOpenSys/usr/bin/sh, is the Korn shell.
