i5/OS(R) Portable Application Solutions Environment (i5/OS PASE) includes three shells (Korn, Bourne, and C Shell) and over 200 utilities that run as i5/OS PASE programs. i5/OS 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 i5/OS PASE shells and utilities, see the following topics. You can also find information about what's new in this release and how you can print this topic.
Using the shells and utilities
The i5/OS PASE default shell (/QOpenSys/usr/bin/sh) is the Korn shell.
A simple way to access i5/OS PASE shells and utilities is to call program Run an i5/OS PASE Terminal Session (QP2TERM), which presents an interactive display with a command line that lets you enter i5/OS PASE commands. You can also call program Run any i5/OS PASE program (QP2SHELL) to run any i5/OS PASE program, including a shell or utility.
Many i5/OS PASE utilities have the same name (with similar options and behavior) as QShell utilities in directory /usr/bin, so i5/OS PASE utilities are provided in directory /QOpenSys/usr/bin or /QOpenSys/usr/sbin. The i5/OS PASE PATH environment variable should generally include directories /QOpenSys/usr/bin, /QOpenSys/usr/bin/X11 and /QOpenSys/usr/sbin when running an i5/OS PASE shell. See Run any i5/OS PASE program (QP2SHELL) for information about setting initial values for i5/OS PASE environment variables.
