Utility of the Month Switching gears, I'd like to introduce the utility of the month, which I hope will become a regular feature of this column. In this part of the column, I'll try to introduce you to a different utility each month. You may be familiar with some of them, but some may surprise you. RCS is great when you want to manage oft-edited files. RCS allows you to retrieve past versions of your document.
Concurrency control allows multiple users to work on a document.
Issue the command ci -u yourfile . You'll be prompted to enter a brief summary of the file's contents. After the file is checked in, you'll notice that it's marked read only. You'll also be able to find a file called yourfile,v in the RCS directory. You'll be granted write access to the file.
