Answer 1

In command mode:

[range]j[lines] 

EG: here you want to make the entire buffer:

 %j 

If you just want to make 10 lines from the current cursor position:

 j10 

If you do not want to replace newlines with spaces! after j.

 %j! j!10 

And for uberfancy:

 5j20 

Goes to line 5 and joins the next 20 lines.

Answer 2

The most intuitive approach would be to use the vim shift + v visual linear mode. All you have to do is select the content you want to combine into one line, then press shift + j .

Answer 3

Use the J (uppercase) key. He will join you

Check this thread for more information on joining options and see the Help page.

Answer 4

In this specific example, the following commands will work:

 :1, 21 j 

or

 :%s/\n/ /g 

Answer 5

Or combine everything: from the opening square bracket to the closing square bracket (provided that there are a lot of them in your file) and leaving the other lines unchanged

 :g/\[/,/\]/j 

it's quick and easy.

Answer 6

 :g/\[/,/\]/j 

Or

 /^CATEGORIES :v//-1j 

And if you have:

 edit "Komputer" ala ala next edit "FortiGate" ala ala next :g/edit/,/next/j
