In these cases the easiest way is to use the import command. An example is probably the easiest way to explain how to use it. If the files you want to install in CVS reside in myproj, and you want them to appear in the repository as $CVSROOT/myproj, you can do this:Starting a project with CVSBuild the myproj directory tree.$ cd myproj $ cvs import -m “Imported sources“ myproj d11e start Starting a project with CVSCongratulations! If you ran that command (or something similar), youve finally done something that affects the repository. Reading over the output of the import command, youll notice that CVS precedes each filename with a single letter - in this case, “N“ for “new file“. The use of a single letter on the left to indicate the status of a file is a general pattern in CVS command output. Well see it later in checkout and update as well. ReminderYou might think that, having just imported the project, you can start working in the tree immediately. This is not the case, however. The current directory tree is still not a CVS working copy. It was the source for the import command, true, but it wasnt magically changed into a CVS working copy merely by virtue of having been imported. To get a working copy, you need to check one out from the repository. Checking Out A Working CopyThe command to check out a project is exactly what you think it is: $ cvs checkout myproj Making A Change Finding Out What You (And Others) Did “cvs update” or “cvs up”cvs updateUsage: cvs update -APdflRp -k kopt -r rev|-D date -j rev-I ign -W spec files.-A Reset any sticky tags/date/kopts.-P Prune empty directories.-d Build directories, like checkout does.-f Force a head revision match if tag/date not found.-l Local directory only, no recursion.-R Process directories recursively.-p Send updates to standard output (avoids stickiness).-k kopt Use RCS kopt -k option on checkout.-r rev Update using specified revision/tag (is sticky).-D date Set date to update from (is sticky).-j rev Merge in changes made between current revision and rev.-I ign More files to ignore (! to reset).-W spec Wrappers specification line.Status of fileU file The file was brought up to date with respect tothe repository. This is done for any file thatexists in the repository but not in your source,and for files that you havent changed but arenot the most recent versions available in therepository.A file The file has been added to your private copy ofthe sources, and will be added to the sourcerepository when you run cvs commit on thefile. This is a reminder to you that the fileneeds to be committed.Status of fileR file The file has been removed from your private copyof the sources, and will be removed from thesource repository when you run cvs commit onthe file. This is a reminder to you that thefile needs to be committed.M file The file is modified in your working directory.M can indicate one of two states for a fileyoure working on: either there were no modificationsto the same file in the repository, sothat your file remains as you last saw it; orthere
