Step 2 of 2

Mass edit a data file

Mass edit a data file

This server table was edited by hand, badly. Make it match the target shown in the panel below the prose, exactly — same lines, same order, one server per line.

What’s wrong with the buffer, top to bottom:

  • four host values are wrapped in single quotes instead of double quotes
  • two host values have no quotes at all
  • every server reads enabled = false and should read enabled = true
  • three servers are marked retired = true and their lines should go

Every fault repeats, so a fix that works for one should be made to work for all of them at once, or be repeated cheaply. If a step has you stuck, lesson 9 covers search and moving between matches, lesson 10 the surround commands, and lesson 11 one cursor per match and per line. Undo is always there if a change goes wrong.
