CVS<\/strong> Tips & Tricks<\/span><\/h1>\n

The CVS<\/strong> commands here assume that you are using the command line version of CVS<\/strong>. Tips and tricks for a specific CVS<\/strong> GUI are specific to each GUI and do not really belong here.<\/p>\n

Viewing the commit log of a file.<\/h2>\n

$ cvs status filename<\/em><\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Performing a CVS<\/strong> diff<\/span><\/h2>\n

After developers have checked in updates to the code it may be beneficial to see what has changed, either to help solve bugs or to track changes. There are several option to do this.<\/p>\n

    \n
  1. Perform a diff between complete branches: <\/strong><\/li>\n<\/ol>\n
    \n\n\n\n
    $ <\/strong>cvs -q diff -u -r BRANCH1 -r BRANCH2 <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
      \n
    1. Perform a diff between a single file in two branches: <\/strong><\/li>\n<\/ol>\n
      \n\n\n\n
      $ <\/strong>cvs -q diff -u -r BRANCH1 -r BRANCH2 filename <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
        \n
      1. Perform a diff between different versions of a file: <\/strong><\/li>\n<\/ol>\n
        \n\n\n\n
        $ <\/strong>cvs -q diff -u -r version1 -r version2 filename <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
          \n
        1. Perform a diff between working version and most up to date file in database: <\/strong><\/li>\n<\/ol>\n
          \n\n\n\n
          $ <\/strong>cvs -q diff -u filename <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
            \n
          1. Perform a diff between working version and a specific database version: <\/strong><\/li>\n<\/ol>\n
            \n\n\n\n
            $ <\/strong>cvs -q diff -u -r version filename <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

            Retrieving <\/strong>CVS Information on Files<\/strong><\/span><\/h2>\n

            To retrieve the current version and other relevant information about a file run:<\/p>\n

            \n\n\n\n
            $ cvs status filename <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

            To retrieve the entire change log pertaining to a file run:<\/p>\n

            \n\n\n\n
            $ cvs log filename <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

            Retrieving CVS Files Based Upon Revision<\/span><\/strong><\/h2>\n

            To retrieve a file from CVS<\/strong> based upon a revision number perform the following:<\/p>\n

            \n\n\n\n
            $ cvs -q up -Pd -r revision filename <\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
