?設計一套SAP監控系統

http://blog.csdn.net/bayaci/archive/2009/10/13/4666456.aspx

顯示系統df（linux ）/ bdf (hpunix)的信息


執行代碼，獲取諸如bdf /usr命令后的信息：
DiskInfo diskInfo = new DiskInfo();
diskInfo.info(directory);
long used = diskInfo.getUsed();
long free = diskInfo.getAvailable();
long kbyte = diskInfo.getKbyte();






代碼如下：
import java.io.IOException;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.util.StringTokenizer;

?????????? return Long.parseLong( value );
?????? }
?????? catch( NumberFormatException nfe ) {
?????????? throw new NumberFormatException( "On value "+value+": "+nfe.getMessage() );
?????? }
?? }
