There is nothing to stop scammers from sending email claiming to be coming from your domain.
|

And the older it gets, the more valuable it is for spoofing.
|

|

Just add these two TXT records to the DNS for your domain:
|

|

|

Name | Type | Value
|

:------|:----:|:-----

Open a CSV table (I made this one with `:r!sed 's/:/,/g' /etc/passwd | head`).
|
||||
|
||||
|
||||
```csv
|
||||
root,x,0,0,,/root,/bin/bash
|

|
||||
systemd-network,x,980,980,systemd Network Management,/,/usr/bin/nologin
|
||||
```
|
||||
|
||||
Highlight the table.
|
||||
|
||||
- Go to the top, with 'root'.
|
||||
- Type `V9j`.
|
||||
- `:!column -ts, -o '|'`
|
||||
- Return!
|
||||
|
||||
|
||||
```csv
|
||||
root |x|0 |0 | |/root |/bin/bash
|
||||
bin |x|1 |1 | |/ |/usr/bin/nologin

|
||||

|
||||
systemd-network |x|980 |980 |systemd Network Management|/ |/usr/bin/nologin
|
||||
```
|
||||
|
||||
The command displays as `:'<,'>!column -ts, -o '|'`.
|
||||
|
||||
This looks better, but the spacing is bad because the output separate is `-o '|'`.
|
||||
You can put spaces around that pipe by making the separator a pipe (`-s'|'`)
|
||||
and making the output separator a pipe with spaces (`-o' | '`).
|
||||
|
||||
```vim
|
||||
:'<,'>!column -ts'|' -o ' | '
|
||||
```
|
||||
|
||||
|
||||
```csv
|
||||
root | x | 0 | 0 | | /root | /bin/bash
|
||||
bin | x | 1 | 1 | | / | /usr/bin/nologin
|
||||
daemon | x | 2 | 2 | | / | /usr/bin/nologin

||||

|
||||
systemd-network | x | 980 | 980 | systemd Network Management | / | /usr/bin/nologin
|
||||
```
|
||||
|
||||
Make a header by copying the top line and replacing text (`yypkR`).
|
||||
|
||||
That's nicer, but the formatting's wrong again.
|
||||
|
||||
```markdown
|
||||
User | Passwords | UID | GID | Description | Home | Shell
|
||||
root | x | 0 | 0 | | /root | /bin/bash
|
||||
[...]
|
||||
```
|
||||
|
||||
Time to fix it with `:'<,'>!column -ts'|' -o'|'`.
|
||||
|
||||
|
||||
```csv
|
||||
User | Passwords | UID | GID | Description | Home | Shell
|
||||
----------------- | ----------- | ------- | ------- | ---------------------------- | ----------------- | ----------
|

root | x | 0 | 0 | | /root | /bin/bash

bin | x | 1 | 1 | | / | /usr/bin/nologin

daemon | x | 2 | 2 | | / | /usr/bin/nologin
|
||||
mail | x | 8 | 12 | | /var/spool/mail | /usr/bin/nologin

|
||||
systemd-network | x | 980 | 980 | systemd Network Management | / | /usr/bin/nologin
|
||||
```
|
||||
|
||||
Now we just need the spacer line.
|
||||
Copy the top line (`yyp`) and replace (`:s/not-pipe/-/g`).
|
||||
You can say 'not the pipe symbol' with `[^|]` or 'not-pipe-or-colon' with `[^:|]`.
|
||||
|
||||
```vim
|

:s/[^:|]/-/g

This markdown table is badly messed up:

```markdown

| format_md.md | vim|

```
|
||||
|
||||
Highight from the top with `V6j`, then run `column` to fix the output:
|
||||
|
||||
```vim
|
||||
:!column -ts'|' -o '|'
|
||||
```
|
||||
|
||||
It displays like this:
|
||||
|
||||
```vim
|
||||
:'<,'>!column -ts'|' -o '|'
|
||||
```
|
||||
|

```
|
||||
|
||||
|
||||
That's better, but the header is broken.
|
||||
Fix is by replacing spaces with dashes.
|
||||
|
||||
```vim
|
||||
:s/ /-/g
|
||||
```
|
||||
|
||||
The lines have too much whitespace.
|
||||
You can fix this with the 'truncate' command, to squeeze repeating spaces or dashes.
|
||||
|
||||
|
||||
```vim
|
||||
tr -s ' -' |column -ts '|' -o '|'
|
