Batch file 如何使用批处理修复此（筛选程序）？

我有一个名为

file.txt的文本文件，其中包含，

Combo: testing123mail@gmail.com:password
As Combo: 
abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
some text here
some more text here
As Combo: hadvsfhia@ahfjbadj.com:password@1
some random text here
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
hadvsfhia@ahfjbadj.com:password@1
testing123mail@gmail.com:password
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
hadvsfhia@ahfjbadj.com:password@1
testing123mail@gmail.com:password
Combo:
Combo:
Combo:
As
As
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

我正在运行下面的代码，只过滤上面文本文件
file.txt中的
mail:pass

for /f "tokens=3" %%a in ('type file.txt^|find "As Combo:"') do >>mail.txt echo %%a
for /f "tokens=2" %%b in ('type file.txt^|find "Combo:"') do >>mail.txt echo %%b
for /f "tokens=1" %%c in ('type file.txt^|find ":"') do >>mail.txt echo %%c

邮件.txt中的预期输出
，

Combo: testing123mail@gmail.com:password
As Combo: 
abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
some text here
some more text here
As Combo: hadvsfhia@ahfjbadj.com:password@1
some random text here
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
hadvsfhia@ahfjbadj.com:password@1
testing123mail@gmail.com:password
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
hadvsfhia@ahfjbadj.com:password@1
testing123mail@gmail.com:password
Combo:
Combo:
Combo:
As
As
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

但是，我得到的实际输出是，

Combo: testing123mail@gmail.com:password
As Combo: 
abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
some text here
some more text here
As Combo: hadvsfhia@ahfjbadj.com:password@1
some random text here
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
hadvsfhia@ahfjbadj.com:password@1
testing123mail@gmail.com:password
iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

abcdefghijklmnopqrstuvwxyz@gmail.com:ajfbdf
hadvsfhia@ahfjbadj.com:password@1
testing123mail@gmail.com:password
Combo:

iloveu@gmail.com:passypassyword123
goldenmammy@hotmail.com:youtube123

注意：邮件id和密码在不同的文本文件中会有所不同。例如，上面给定的邮件id和密码是我随机键入的。
我建议您使用vbscript中的正则表达式来提取此类数据。下面是一个示例，向您展示如何提取此类数据，因此，如果您希望我将在vbscript中为您发布解决方案，只需回答您的问题并添加标签vbscript！为什么不为

添加find，并在提取包含它的所有电子邮件地址时查看它们呢。
