An Escape (!) to the Host Operating System

 Calling Sequence ! cmd arg1 arg2

Parameters

 cmd - operating system command arg1 - arguments passed to operating system

Description

 • When the ! character appears as the first character in a line, it is treated as an escape to host operator.
 • This allows the execution of host system commands from within a Maple session. All characters on the line following the escape character are treated as a command to the host system.
 • The result is the return status of the command performed, which is operating system dependent, but usually 0 indicates success and any other value indicates failure.
 • Important: There may be implementation restrictions on some host operating systems.

Example

 > !pwd;
