Clean Nmap output [IP:Port]

发布于 2020-12-03 18:10:38

I would like to obtain the Nmap output in the following format (if possible, with a one-line command):

2001:4860:4860::8888:53
2001:4860:4860::8888:443
2001:4860:4860::8888:853
2001:4860:4860::8844:53
2001:4860:4860::8844:443

Here is the original output:

Nmap 7.80 scan initiated Thu Dec  3 17:04:38 2020 as: nmap -6 -p- -iL out.txt
Host: 2001:4860:4860::8888 (dns.google) Status: Up

nmap ... | awk '/^Host/ && /Ports/ { for (i=1;i<=NF;i++) { if (match($i,/open/)) { split($i,map,"/"); printf "%s:%s\n",$2,map[1] } } }'

Search the output for lines starting with Host and also containing Port. Loop through each space delimited field and check for open in the field using the match function. If there is a match, split the field into an array map using the split function and use the first index of the array as the port. Print the second delimited field along with the port.

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
