The ! Simics command can be used to run command line
commands. It will take everything after the ! sign and run it in
a command interpreter (the current shell, on Linux, and cmd.exe,
on Windows). For example:
simics> !dir c:\
This will run dir c:\ as if typed at the cmd.exe prompt and show the result in the Simics console.
simics> !uname -a
This will run uname -a using the current shell and show the result in the Simics console.
