There is a text like this
As of initscripts-2012.07.5, the default format of /etc/rc.conf and
/etc/crypttab have changed. See their respective man pages for
more details.
--BEGIN--
The purpose of this change is to unify the configuration of systemd
and initscripts. This will allow us to share code and documentation,
and should make maintenance of initscripts simpler in the long-run.
--END--
The old format is still supported, so old config files should still
work unchanged.
Hopefully --BEGIN-- Delete all the lines between --END--. Is there any direct method for vim?
Another additional question is how to add a piece of content when there is already a --BEGIN-- mark.
The above all hope to process text files in a scripted manner.
Just an example, the number of lines between --BEGIN--,--END-- is uncertain
Marking this manually is a bit laborious. The actual file is not small and has a similar structure
More.

:g/--BEGIN--/,/--END--/dIf you want to delete the blank lines before and after at the same time
:g/--BEGIN--/-1,/--END--/+1dvim can do it,
In command mode:
The _ is the key, this can match multiple lines.
There is already a way to replace the --BEGIN-- logo. This can also be done using the above replacement idea
:%s/^--BEGIN--/&Content to be replaced/g
Move the cursor to the beginning
Esc v to enter view mode
j Scroll down to select the operation part
d Delete x Cut Both are OK
Since you want to script it, just use sed:
ndd, n is the number of rows to be deleted.
