The last argument is the calibration file or profile, it's a separate argument, not a parameter to the 'V' flag. Notice that the usage looks like this: usage: dispwin [options] [calfile] -v Verbose mode -d n Choose the display from the following list (default 1) 1 = 'DISPLAY1, at 0, 0, width 1280, height 1024 (Primary Display)' -p ho,vo,ss Position test window and scale it -i Run forever with random values -m Manually cycle through initial values -f Test grey ramp fade -r Test just Video LUT loading -n Test native output (rather than through Video LUT) -c Load a linear display calibration -x Don't exit after loading a display calibration -V Verify that calfile is currently loaded calfile Load display calibration (.cal or .icm) into LUT, and exit The -V flag has no parameter after it. The very last argument is the calibration file. All arguments are separated by a white space, but parameters to options may or may not be separated by a white space from the associated option at the users discretion. So -r need to be separated from -n with white space. -V needs to be separated from calfile by white space. But the display selection to the -d parameter may come directly after it: -d1 or not -d 1 If there were a flag with a usage like this: -X [extrafile] Then the optional 'extrafile' could come directly after -X, because it's a parameter to the option -X, rather than being a separate option or file parameter in its own right.
