You are in vi command mode with unsaved changes. Type the command that writes the file and then exits the editor.
LPIC-1 Exam 101-500, objective 103. GNU and Unix commands easy
Draft — not checked yet. This question was written from the published exam objectives and cites the clause it comes from, but nobody has yet read it against that clause and signed for it.
It is kept out of search results and out of mock exams until they have. Read the source below before you take the answer as settled.
Answer
Type the answer.
Accepted answers
:wq:xZZ:wq!
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
':wq' writes the buffer and quits. ':x' and the command-mode keystroke 'ZZ' do the same but write only when the buffer was actually modified, so they leave the file's timestamp untouched otherwise. To leave WITHOUT saving, use ':q!' instead.
