I suspect this will get migrated to U&L or to stackoverflow. Check out http://serverfault.com/help/on-topic. Thanks! – Falcon Momot Jan 27 '14 at 10:21

2You're doing it wrong. Get proper version control, such as git. – Michael Hampton Jan 27 '14 at 14:03

If you are using vim, it uses a swap file to track in-progress changes, and will typically notify you if someone else is currently modifying the same file. However, this should be considered an unreliable safety net, and not something to plan on. In other words, it might work, but it is definitely the wrong solution.
If you have multiple people editing the same file(s), and collaborating on the same work, you should be using a Revision Control system. There are dozens (if not hundreds) of available options, many of them free and open source. Using one of these is the correct solution.
I'd start by looking into one or more of the more popular Version Control Systems (and maybe review some Wikipedia articles on the topic to understand what they do and how they work). Popular choices that will probably work well for you include: Subversion, Fossil, Git, Bazaar, Mercurial, and Monotone. Personally, I'm a big fan of Fossil for smaller projects, but any of those listed will probably work just fine for you.
