Now, for any files that you want CVS to control, register them in the repository: cvs add sample. Go ahead and commit them: cvs commit -m "original file" sample. This latter form is usually more useful. Write good log messages! It updates your working directory from the repository, but also tells you status of files.

Try it: cvs update Probably all you got was a message like "cvs update: Updating. The result of update will have the letter M next to the sample. It's quick to install and relatively intuitive to use. Privacy Policy. Contact Us. Terms of Use.

When it comes to simply grabbing the latest sources, that's about all you need to know. Now, we take a look at how to interact with CVS as a developer.

As a developer, you'll need to modify files on CVS. To do this, simply make the appropriate changes to your local copy of the repository.

The changes you make to the sources are not applied to the remote repository until you explictly tell cvs to "commit" your changes. When you've tested all your modifications to ensure that they work properly and you're ready to apply your changes to the repository, follow this two-step process. First, update your sources by typing the following command in your main source directory:.

As we've seen earlier, "cvs update" will bring your sources up-to-date with the current version in the repository -- but what happens to the changes you've made? Don't worry, they aren't thrown away. If another developer made changes to a file that you haven't touched, your local file will be updated so that it's in-sync with the version on the repository. And, if you modified lines of a local file, and another developer deleted lines , added 12 new lines at the end of the file, modified lines and then committed their changes to the repository before you, cvs will intelligently merge these changes into your locally modified copy so that none of your changes are lost.

This allows two or more developers to work on different parts of the same file at the same time. However, if two or more developers have made changes to the same region of the same file , then things get a bit more complicated.

If that happens, then cvs will tell you that there's been a conflict. No work will be lost, but a bit of manual intervention will be required, since cvs now requires your input on how to merge the conflicting changes.

We'll look at exactly how conflicts can be resolved in just a little bit, but for now, let's assume that there are no conflicts after you typed "cvs update -dP" -- there usually aren't. With no conflicts, your local sources are up-to-date, and you're ready to commit your changes to the repository by typing the following command in your main source directory:.

Before actually committing your changes to the remote repository, cvs will fire up your default editor so that you can type in a description of your modifications.

Once you've entered your comments, saved the file and exited the editor, your changes and comments will be applied to the remote repository and will be available to the other developers in your team. It's really easy to view the complete history of a particular file, along with any comments that the developers including you may have made when committing. To view this information, type:. The "cvs log" command is recursive, so if you want to see the complete log for an entire directory tree, just enter the directory and type:.

You may want to use another editor than the one cvs starts by default when you type "cvs commit". Alternatively, you can also specify a log message as a command line option so that cvs doesn't need to load up an editor in the first place:. By creating a. Here's a recommended default. In addition to setting useful options for a bunch of cvs commands, the first line of the. Also, once you have this. It's really easy to add a source file to CVS.

First, create the file with your favorite text editor. Then, type the following:. This will tell cvs to add this file to the repository the next time you do a cvs commit. CSV stands for " c omma- s eparated v alues". Its data fields are most often separated, or delimited , by a comma. Here, the fields of data in each row are delimited with a comma and individual rows are separated by a newline. A CSV is a text file , so it can be created and edited using any text editor.

To create a CSV file with a text editor, first choose your favorite text editor, such as Notepad or vim , and open a new file.

Then enter the text data you want the file to contain, separating each value with a comma and each row with a new line. Save this file with the extension. You can then open the file using Microsoft Excel or another spreadsheet program. It would create a table of data similar to the following:.
