删除多余的vim和viminfo行

Question

I am making a cat with 2 files

1.txt content:

hi

2.txt content:

everyone

cat 2.txt >> 1.txt

1.txt new content:

hi
# This viminfo file was generated by Vim 7.2.
# You may edit it if you're careful!

# Value of 'encoding' when this file was written
*encoding=utf-8
...
everyone

It adds a lot of info that I don't want.

could you help me?

Regards.

In the final file, just do

:g/^#/d

g It is for Global

^# It will find all the lines starting with #

d It is for delete
