tshark的使用技巧（wireshark的命令行，类似tcpdump）：转换格式，设置filter
tshark一般在 C:\Program Files\Wireshark
使用管理员权限 打开cmd
tshark -D 列出支持抓包的接口：
c:\Program Files\Wireshark>tshark.exe -D

tshark -i 使用指定接口：
c:\Program Files\Wireshark>tshark.exe -i \Device\NPF_{23E14E7F-5D8F-42DB-AEA8-45038429FD06}
Capturing on 'WLAN'
1 0.000000 192.168.100.23 → 123.182.48.28 TCP 54 3488 → 443 [FIN, ACK] Seq=1 Ack=1 Win=255 Len=0
2 0.000009 192.168.100.23 → 180.101.51.73 TCP 54 3501 → 80 [RST, ACK] Seq=1 Ack=1 Win=0 Len=0
tshark -c 指定抓包个数：
c:\Program Files\Wireshark>tshark.exe -i \Device\NPF_{23E14E7F-5D8F-42DB-AEA8-45038429FD06} -c 10
tshark -w写入文件：
c:\Program Files\Wireshark>tshark.exe -i \Device\NPF_{23E14E7F-5D8F-42DB-AEA8-45038429FD06} -c 10 -w wlan.pcap
Capturing on 'WLAN'
10
tshark -r读取：
c:\Program Files\Wireshark>tshark.exe -r wlan.pcap
转换格式：
默认tshark live capture只保存为pcap or pcapng。只能先存为pcap文件，再转换为其他文件格式：
c:\Program Files\Wireshark>tshark.exe -i \Device\NPF_{23E14E7F-5D8F-42DB-AEA8-45038429FD06} -c 10 -F k12text -w wlan.txt
tshark: Live captures can only be saved in pcap or pcapng format.
tshark -F 列出支持的文件格式：
c:\Program Files\Wireshark>tshark.exe -F
tshark.exe: option requires an argument -- 'F'
tshark: The available capture file types for the "-F" flag are:
5views - InfoVista 5View capture
btsnoop - Symbian OS btsnoop
commview - TamoSoft CommView
dct2000 - Catapult DCT2000 trace (.out format)
erf - Endace ERF capture
eyesdn - EyeSDN USB S0/E1 ISDN trace format
k12text - K12 text file
tshark -r读取，-F另存为其他格式：
c:\Program Files\Wireshark>tshark.exe -r wlan.pcap -F k12text -w wlan.txt
tshark设置filter有2种方式：
tshark -f ""
c:\Program Files\Wireshark>tshark.exe -i \Device\NPF_{23E14E7F-5D8F-42DB-AEA8-45038429FD06} -f "host 172.175.234.12"

直接写filter
c:\Program Files\Wireshark>tshark.exe -i \Device\NPF_{23E14E7F-5D8F-42DB-AEA8-45038429FD06} host 172.175.234.12
