--port=21,22
--port=21,22,23,5900-5900
--reverse display DNS reverse lookup
--reversevalid only display results having a valid reverse dns, except if
ports specified
--geo display geoip (free maxmind)

--hugescan allow number of ip/port combinaison greater than 16580355
(i.e a /24 network with port range 0-65535)
--display display result format (json,xml,console)
default console
--outfile dump result in a file
--json shortcut for --display=json

--version display version number
使用实例
语法：
evilscan [options]
扫描网络中的一台主机上的 0 -4000 端口，抓取 banner 并仅显示 open 的端口：
[root@localhost ~]# evilscan 192.168.0.10 --port=0-4000 --banner
192.168.0.10|139||open
192.168.0.10|135||open
192.168.0.10|110||open
192.168.0.10|25||open
192.168.0.10|445||open
192.168.0.10|2381||open
192.168.0.10|2301||open
192.168.0.10|3389||open
扫描网络中的一台主机上的 0 -100 端口，抓取 banner，仅显示打开的端口，使用 json 格式输出，每秒显示进度状态：
[root@localhost ~]# evilscan 192.168.0.13 --port=0-100 --banner --isopen --istimeout --progress --json
{"_timeStart":"N/A","_timeElapsed":"N/A","_jobsTotal":100,"_jobsRunning":0,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Starting","_message":"Starting"}
{"_timeStart":1628685339594,"_timeElapsed":999,"_jobsTotal":100,"_jobsRunning":100,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Running","_message":"Scanning 192.168.0.13:100"}

{"ip":"192.168.0.13","port":25,"status":"open"}
{"ip":"192.168.0.13","port":22,"banner":"SSH-2.0-OpenSSH_7.9-hpn14v15\\r\\n","status":"open"}
{"ip":"192.168.0.13","port":80,"status":"open"}
{"_timeStart":1628685339594,"_timeElapsed":2019,"_jobsTotal":100,"_jobsRunning":0,"_jobsDone":100,"_progress":100,"_concurrency":500,"_status":"Finished","_message":"Scanned 192.168.0.13:80"}
提示：并发数默认为100。如果想扫描大量的 ip/ 端口范围，可以使用 --concurrency 选项（例如 1000）。
如果要突破 1024 个打开套接字的限制，使用下面命令更新限制参数：
