个人感觉这种纯P困难，就用python写了个 用不了几行可以搞定。不过大文件没测试 没怎么考虑效率。

import shutil

str1 = "错误"
str2 = "AutoConfig"
file = "123.txt"
file2 = "d:\\456.txt"
file3 = "d:\\789.txt"

with open(file,encoding="utf-8") as f:
    last10 = "".join(list(f)[-10:])

if str1 in last10 and str2 in last10:
    shutil.copy(file, file2)
    with open(file2,encoding="utf-8") as f:
        flst = list(f)
        last4th6chars = flst[-4][:6]    #前6个是  "错误 201"
        with open(file3,"w",encoding="utf-8") as fw:
            for line in flst[-20:]:
                if last4th6chars in line: fw.write(line)
