![]() git push upload all committed history to a remote copy of the repository.git merge adds the history of one branch to another branch.git checkout switches from the current branch to another specified branch and may create a new branch if the one specified does not exist.git branch is used to manage branches both locally and remotely within the repository.git status prints information about the current status, including what has deviated from the last commit.git commit records the current status of objects in the repository into a commit.git add adds files and directories to be tracked by Git new files or directories are not tracked by default.git init / git clone are used to create a new repository or to create a copy of an existing repository.The basic Git commands for working in a repository include: Linus Torvalds created Git in 2005 to support the ongoing development of the Linux kernel by widely distributed developers. Git is a distributed CVS supporting local copies of a repository and merging of changes into a central version (sound familiar?). This permanent record can be very valuable in determining when, and by whom, changes were introduced into the repository. Once a change is recorded in the Mercurial history, it is immutable and cannot be removed – except via a rollback which is similarly recorded as a new change. ![]() ![]() This is reflected by the projects that choose Mercurial as their VCS such as Mozilla and NGINX. This approach to change tracking is especially effective for projects that are very large – in terms of the number of files and number of contributors. The revision log structure allows Mercurial users to interact with repository contents at arbitrary points in time ad hoc. hg merge to join different lines of historyĬhanges are tracked linearly over time in a data structure called a revision log (RevlogNG ).hg serve create a web server where collaborators can see the history and pull from it.hg push sends all changes from the current repository into another repository.hg pull brings all of the changes from another repository into the current repository.hg log to see all changes in the repository.hg commit saves changes in the current repository.Many users find the syntax simpler and more intuitive, helping to improve development velocity. The command syntax for working with Mercurial is designed to be very simple and easy for users to quickly understand. Mercurial is a distributed CVS supporting local copies of a repository and merging of changes into a central version. Both released in 2005 under the GNU Public License ( GPL), these solutions have seen widespread adoption thanks to similarities between them and healthy competition due to their differences let’s examine Mercurial vs Git. Two prominent distributed VCS solutions are Mercurial and Git. One pattern that has been widely adopted over the last 10 years is distributed VCS, where copies of a single source of truth repository are shared – or clone’d – out to disparate systems such as developer laptops then, after changes are made locally, data is merge’d back into the source of truth following a predefined pattern – such as trunk-based. Not only does an effective VCS need to support the mechanical actions required by DevOps – tracking changes, documenting updates, merging data, and more – but it is also in use all the time by the developers and so must include features that are a good fit for the needs of the team – understandable command syntax, provide visibility into changes, and so on. Version Control Systems (VCS) can play a critical role for DevOps teams getting started, working to maintain efficiency and velocity, or improve team performance.
