==============================================================================
A.25. )system
==============================================================================
User Level Required: interpreter
Command Syntax:
- )system cmdExpression
Command Description:
This command may be used to issue commands to the operating system while
remaining in OpenAxiom. The cmdExpression is passed to the operating system for
execution.
To get an operating system shell, issue, for example, )system sh. When you
enter the key combination, Ctrl-D (pressing and holding the Ctrl key and then
pressing the D key) the shell will terminate and you will return to OpenAxiom. We
do not recommend this way of creating a shell because Lisp may field some
interrupts instead of the shell. If possible, use a shell running in another
window.
If you execute programs that misbehave you may not be able to return to
OpenAxiom. If this happens, you may have no other choice than to
restart OpenAxiom and restore the environment via )history )restore,
if possible.
