Why does running a command with Runtime.exec() generate output under Windows but not generate output under Linux?
Created May 4, 2012
Nathan Meyers Output from commands executed by Runtime.exec()
is sent to streams that your application has to read: you can
call Process.getInputStream() to get normal
output from the command and
Process.getErrorStream() to get error output.
Many MS-DOS executables send their output directly to the console instead of normal file streams, which is why you see it even if you are not reading the streams you should be reading.
