Select the ranodm percent of the line in the data set

Hello ;
I have a file which has one column with 7200 ID. These line have been repeated for certain of these ID. for example, ID number 200 repeated 3 times, ID number 201 repeated 2 times and etc. How could I select 20% of the ID numbers randomly without repetition?

Regards
Sajjad

glutIgnoreKeyRepeat(3GLUT)					       GLUT						glutIgnoreKeyRepeat(3GLUT)

NAME
glutIgnoreKeyRepeat - determines if auto repeat keystrokes are reported to the current window SYNTAX
void glutIgnoreKeyRepeat(int ignore); ARGUMENTS
ignore Non-zero indicates auto repeat keystrokes should not be reported by the keyboard and special callbacks; zero indicates that auto repeat keystrokes will be reported. DESCRIPTION
glutIgnoreKeyRepeat determines if auto repeat keystrokes are reported to the current window. The ignore auto repeat state of a window can be queried with glutDeviceGet(GLUT_DEVICE_IGNORE_KEY_REPEAT). Ignoring auto repeated keystrokes is generally done in conjunction with using the glutKeyboardUpFunc and glutSpecialUpFunc callbacks to repeat key releases. If you do not ignore auto repeated keystrokes, your GLUT application will experience repeated release/press call- backs. Games using the keyboard will typically want to ignore key repeat. GLUT IMPLEMENTATION NOTES FOR X11 X11 sends KeyPress events repeatedly when the window system's global auto repeat is enabled. glutIgnoreKeyRepeat can prevent these auto repeated keystrokes from being reported as keyboard or special callbacks, but there is still some minimal overhead by the X server to con- tinually stream KeyPress events to the GLUT application. The glutSetKeyRepeat routine can be used to actually disable the global sending of auto repeated KeyPress events. Note that glutSetKeyRepeat affects the global window system auto repeat state so other applications will not auto repeat if you disable auto repeat globally through glutSetKeyRepeat. SEE ALSO
