To be specific I would like to know how I can send any command to the
Linux operating system from my FreePascal program?

Just doing this seems not to cut it:

writeln('sudo ifup wlan0');

This just *displays* the text on the program console, but I want it to
go to the operating system as a command...

On Windows one has to start cmd with the wanted command as a
parameter, what is the corresponding method on Linux from within
FreePascal?
