Question

我有一个文件，每行包含一个CIDR地址和端口：

192.168.1.0/24 3306  
192.168.1.0/24 55982  
10.10.10.0/24 5800  
10.10.10.0/24 39690  
10.10.10.0/24 50112  
192.168.1.0/24 3308  
192.168.1.0/24 3312  
192.168.1.0/24 3316

使用GNU Awk 4.1.4（在Linux系统上），最初的想法是将所有端口放在一行上按CIDR地址分组，所以这样做了：

awk '{a[$1]=a[$1] ? a[$1]","$2 : $2} END {for (j in a) {print j" over ports: "a[j]}}' file

192.168.1.0/24 over ports: 3306,3308,3312,3316,55982  
10.10.10.0/24 over ports: 5800,39690,50112

我还想为每个CIDR地址添加一个计数，以获得此结果：

192.168.1.0/24 over 5 ports: 3306,3308,3312,3316,55982  
10.10.10.0/24 over 3 ports: 5800,39690,50112

我已经尝试将值放入数组并打印出密钥，但计数总是达到2。

awk '{a[$1]=a[$1] ? a[$1]","$2 : $2} {h[$1]++;} END {for (i in h) for (j in a) {print j" over "h[i]" ports: "a[j]}}' file

192.168.1.0/24 over 2 ports: 3306,3308,3312,3316,55982  
10.10.10.0/24 over 2 ports: 5800,39690,50112

除了awk之外我还愿意做其他事情，但是由于带有CIDR /端口的文件数百万行，而且awk很快，所以它更可取。有什么想法吗？

这是awk的解决方案：

awk '{ z[$1][++count[$1]]; s[$2]=$1; } 
       END {
         for (i in z)
         { 
           printf( i" over "count[i]" ports: " );
           c=0;
           # print ports according to the key value
           # and the requested format, i.e. port1,port2,...
           for (j in s)
             if(s[j]==i)
                 # we don't want a comma at the end of the line,
                 # after the last port we put a newline
                 if (c<count[i]-1)
                 { 
                   printf(j","); 
                   c++;
                 }
                 else printf(j"\n")
         }
       } 
}' file

及其输出：

10.10.10.0/24 over 3 ports: 5800,39690,50112
192.168.1.0/24 over 5 ports: 3306,3308,3312,3316,55982

Answer 2

没有多暗阵列

@IBAction func facebookLogin(sender: AnyObject) {
AppUtility.loginWithFacebook { (success) in

    if success {
        AppUtility.getUserData({ (success) in
            if success {
                self.performSegueWithIdentifier("completeProfile", sender: nil)

ApplicationDelegate.showTabBarController()
            }
            else {
                print ("Attempting FB Login - 5 ")

                print ("Attempting FB Login - 6 ")

            }
        })
    }
}

Answer 3

$ awk '{cnts[$1]++; ports[$1]=($1 in ports ? ports[$1] "," : "") $2}
       END{for (ip in ports) print ip, "over", cnts[ip], "ports:", ports[ip]}' file
10.10.10.0/24 over 3 ports: 5800,39690,50112
192.168.1.0/24 over 5 ports: 3306,55982,3308,3312,3316

使用awk，将CIDR与端口分组，并使用相应的CIDR计算所有端口
