Question

I got a file with 1000 lines and I need to replace let’s say first 500 lines with any another number – for example 0, and next 500 lines with number that is in this line + 1

Answer 1

In the first of the lines you want to replace, you can do:

500dd

And then:

500I

Input the text you want to place in the 500 lines, follow with enter and exit edit mode. Voila!

If you want to increment numbers written in multiple lines, you could use a macro.

Try:

qq<C-A>jq499@q

• the first q begins the recording of a macro
• the second q is where the macro is to be stored
• C-A means “increase the number in the current line”
• j – go to next line
• third q – finish recording the macro
• 499 – repeat 499 times
• @q – repeat the macro stored in q
