請教大大這個批處理eol=為什么就能把后面的全部去除批處理:

for /f eol=- tokens=1 delims=  %%i in (result.txt) do echo %%i>>s1.txt
nclick="copycode($('code0'));">復制代碼

Result.txt文件內容:

-------------------------------------------------------------------------------

172.87.192.106379Open 
172.87.192.8 6379Open
nclick="copycode($('code1'));">復制代碼

最后得到的s1.txt

nclick="copycode($('code2'));">復制代碼

我想了解的問題: eol=- 這里只將帶 - 的行內容全部去除，但是沒有發現其他哪一點還可以同時去除: 1/21/ 7:57:42 --> Normal Scan: about To Scan 389120 IP Using 1024 Threads以及去除每一行的 6379Open
