You can use  netstat  to check whether a port is available or not   Use the netstat -anp   find  port number  command to find whether a port is occupied by an another process or not  If it is occupied by an another process  it will show the process id of that process   You have to put   before port number to get the actual output  Ex netstat -anp   find   8080

netstat -ano find   port no  will give you the list  a  Displays all connections and listening ports        n  Displays addresses and port numbers in numerical form        o  Displays the owning process ID associated with each connection      example   netstat -ano   find   1900    This gives you the result like this     UDP    107 109 121 196 1900                                          1324   UDP    127 0 0 1 1900                                                1324   UDP       1  1900                                                    1324   UDP     fe80  8db8 d9cc 12a8 2262 13  1900                           1324
