8.157 SH (Shell command)

8.157.1 Function

The SH command passes the given command and the parameters (if any) as-is to the shell for process-
sing. The results of the passed command are displayed on the Hercules console.

The special ‘STARTGUI’ command must be used if the command being started either directly or indirectly
starts a Windows graphical user interface (non command-line) program (e.g. Notepad). If STARTGUI is
not used in such cases then Hercules will hang until the graphical user interface program is closed. Note
that starting a batch file (command line program) that itself starts a graphical user interface program still
requires using STARTGUI.

If “foo.bat” contains “start notepad.exe” then issuing “sh foo.bat” will hang Hercules until Notepad is being
closed. The same applies if “sh start foo.bat” is used. The correct way is using ‘STARTGUI’ for invoking
foo.bat is “sh startgui foo.bat”.
