Created page with "If started as ´view´ the file is opened read-only, you can however write using :!w if you have write permissions on file-system level. Always leave the file using :q or :n,..."

New page

If started as ´view´ the file is opened read-only, you can however write using :!w if you have write permissions on file-system level.

Always leave the file using :q or :n, vi will warn you if you have made unsaved changes. Don't exit using :!wq by default as I did, sometime you will save something you really don't want.

I found some good advise in this [[http://www.lagmonster.org/docs/vi2.html Cheat Sheet]]. A nice tutorial can be found on [[http://www.truth.sk/ http://www.truth.sk/]].
