OS/400 PASE Shells and Utilities

As400s OS/400(R) Portable Application Solutions Environment (OS/400 PASE) includes three shells (Korn, Bourne, and C Shell) and over 200 utilities that run as OS/400 PASE programs. OS/400 PASE shells and utilities provide an extensible scripting environment that includes a large number of industry-standard and defacto-standard commands.

To become more familiar with OS/400 PASE shells and utilities, see the following as400 topics. You can also find information about what's new in this release and how you can print this topic.

OS/400 PASE Commands
system - Run a CL command for OS/400 PASE
qsh, qsh_inout, qsh_out - Run a QShell command for OS/400 PASE
Using the shells and utilities

A simple way to access OS/400 PASE shells and utilities is to call program Run an OS/400 PASE Terminal Session (QP2TERM), which presents an interactive as400 display with a command line that lets you enter OS/400 PASE commands. You can also call program Run any OS/400 PASE program (QP2SHELL) to run any OS/400 PASE program, including a shell or utility.

Many OS/400 PASE utilities have the same name (with similar options and behavior) as QShell utilities in directory /usr/bin, so OS/400 PASE utilities are provided in directory /QOpenSys/usr/bin or /QOpenSys/usr/sbin. The OS/400 PASE PATH environment variable should generally include directories /QOpenSys/usr/bin, /QOpenSys/usr/bin/X11 and /QOpenSys/usr/sbin when running an OS/400 PASE shell. See Run any OS/400 PASE program (QP2SHELL) for information about setting initial values for OS/400 PASE environment variables.

In addition to these utilities, each OS/400 PASE shell supports a number of built-in commands (such as cd, exec, if, etc.). See AIX(R) documentation for information about the built-in commands supported by each OS/400 PASE shell.

The as400 OS/400 PASE default shell (/QOpenSys/usr/bin/sh) is the Korn shell.
