|Executing an external command.|
|system :: String -> IO ExitCode|
Computation system cmd returns the exit code produced when the operating system processes the command cmd.
This computation may fail with
On Windows, system is implemented using Windows's native system call, which ignores the SHELL environment variable, and always passes the command to the Windows command interpreter (CMD.EXE or COMMAND.COM), hence Unixy shell tricks will not work.
|rawSystem :: String -> [String] -> IO ExitCode|
The computation rawSystem cmd args runs the operating system command cmd in such a way that it receives as arguments the args strings exactly as given, with no funny escaping or shell meta-syntax expansion. It will therefore behave more portably between operating systems than system.
The return codes and possible failures are the same as for system.
