請問各位大神
以下是我在cmd下執行nmap -sn -n 192.168.2.*/24的掃描結果

Starting Nmap 7.80 ( https://nmap.org ) at 2020-05-16 23:29 ￥x￥_?D·CRE?!
Nmap scan report for 192.168.2.1

Nmap scan report for 192.168.2.2
Host is up.
Nmap done: 256 IP addresses (6 hosts up) scanned in 2.80 seconds

我想把結果裡面的MAC跟IP放在同一行，中間用-做區隔輸出到txt
像這樣

04:92:26:XX:XX:XX-192.168.2.1
FC:2A:9C:XX:XX:XX-192.168.2.3
90:E6:BA:XX:XX:XX-192.168.2.5
44:23:7C:XX:XX:XX-192.168.2.120

當我手上有MAC的時候可以用for /f+findstr取得我要的IP
目前想出來的方法是把掃描結果存成文件，再從文件個別找出MAC跟IP然後寫入同一份檔案

for /f "tokens=3 delims= " %%i in ('find "MAC" scan.txt') do echo %%i>>mac.txt
for /f "tokens=5 delims= " %%j in ('find "192.168." scan.txt') do echo %%j>>ip.txt
set m=0
for /f "delims=" %%a in (mac.txt) do (set /a m+=1
set a!m!=%%a)
set n=0
for /f "delims=" %%b in (ip.txt) do (set /a n+=1
set b!n!=%%b)
for /l %%c in (1，1，%m%) do (
echo !a%%c!-!b%%c!>>arp.txt)

但是感覺有點太冗長了，不知道大神們有沒有更好的寫法，懇請賜教

更新一下，這是目前寫出來的東西，最近新增了scan arp table的功能
在scan之前，我會先收集mac，收集方式如下:

set /p psn="Scan Product Serial Number[PSN]:"
set /p  cmbmc="Scan  CM   IPMI Mac Address[CMBMC]:"
set /p n1ipmi="Scan Node1 IPMI Mac Address[N1IPMI]:"
set /p n2ipmi="Scan Node2 IPMI Mac Address[N2IPMI]:"
echo set psn=%psn%>>%psn%.bat
echo set cmbmc=%cmbmc%>>%psn%.bat
echo set n1ipmi=%n1ipmi%>>%psn%.bat
echo set n2ipmi=%n2ipmi%>>%psn%.bat

然後放在SAMBA Server上面，用%PSN%.bat做命名
以下是整個scan的腳本
