Thanku Mr.Gabriele Actually I was trying to generate K-point path.
The earlier reply of yours for my question "I would like to generate the list of k-points by using utility program X.KPATH in PWTOOLS" is "I always use "xcrysden" to generate high symmetry k-point and then use this "bk.exe" (I have upload file)to generate all k-point which is along high symmetry.I never use pwtool,butI guess it may be the "kpoint.x". So I installed xcrysden in Linux version but cannot in windows version (for which Cygwin environment is needed). There I was doubt whether I can generate the k-point path in Linux version of xcrysden or not.
