HP-UX System Administrator's Guide: Overview

HP-UX provides the following commonly used shells for command entry:
• sh - the POSIX shell
• ksh - the Korn shell
• csh - the C shell
Though not officially shells, two related utilities work closely with shells to provide
multiple sessions on a single terminal:
shl
The Shell Layer Manager provides a means for interacting with more than one
shell from a single using shell layers. Each layer represents a virtual device. The
current layer is the one that can receive keyboard input. Other layers have input
blocked. Output from multiple layers is multiplexed onto a single terminal. See
shl(1) for complete details.
tsm
The Terminal Session Manager, similar to the Shell Layer Manager, allows a
user to interact with multiple shells from a single terminal. Each shell is bound
to a virtual device emulating a physical terminal. tsm hot keys allow the user
to switch between (and create new) sessions. See tsm(1) for complete details.
The HP System Management Homepage Command Line Interface
If you need to enter a quick command line command from within the HP SMH graphical
user interface and do not want to start up a shell in a separate window, click on the
Tasks menu item near the top of the page and then select either Run Command or Run
Command as Root from the System section on the resulting panel.
