1,python

#!/usr/bin/pythonimport osimport statvfsvfs=os.statvfs("/home")#print vfs#print dir(os.statvfs)#print dir(statvfs)#availsizeavl_size=vfs[statvfs.F_BAVAIL]*vfs[statvfs.F_BSIZE]/(1024*1024*1024)#totalsizetol_size=vfs[statvfs.F_BLOCKS]*vfs[statvfs.F_BSIZE]/(1024*1024*1024)#percentsizepercent=round((tol_size-avl_size)*1.0/tol_size*100,3)#or from __future__ import division round((tol_size*avl_size)/tol_size*100,3)print 'THE HOME DIRS USED_PERCENT IS %s%%'%percent

然后执行chmod a+x xxx.py
python help
命令行中：import os ;import statvfs
然后查看帮帮助：help(os),help(os.statvfs),help(statvfs)

2,C语言

#include <stdio.h>#include <sys/statvfs.h>int main(){    struct statvfs diskInfo;    statvfs("/home/", &diskInfo);    unsigned long long blocksize = diskInfo.f_bsize;    unsigned long long totalsize = blocksize * diskInfo.f_blocks;    printf("Total_size = %llu B = %llu KB = %llu MB = %llu GB\n",        totalsize, totalsize>>10, totalsize>>20, totalsize>>30); //64bit print out    unsigned long long freeDisk = diskInfo.f_bfree * blocksize;     unsigned long long availableDisk = diskInfo.f_bavail * blocksize;     printf("Disk_free = %llu MB = %llu GB\nDisk_available = %llu MB = %llu GB\n",           freeDisk>>20, freeDisk>>30, availableDisk>>20, availableDisk>>30);    return 0;}

然后执行：gcc xxx.c -o diskinfo
可以使用statfs函数，不懂使用man statfs
从上可以看到，函数名称在python中和c中类似，其实有些东西是通用的
