git checkout --track creates a local branch from a remote branch, links them, and replaces the current working files with files from that branch. git fetch downloads changes from a remote repository into the local clone git reset makes the current branch point to some specific revision or branch. git reset --hard makes the current branch point ...
To commit a change in git on the command line, assuming git is installed, the following command is run: [1] git commit -m 'commit message' This is also assuming that the files within the current directory have been staged as such: [2] git add . The above command adds all of the files in the working directory to be staged for the git commit.
Git can be used in a variety of different ways, but some conventions are commonly adopted. The command to create a local repo, git init, creates a branch named master. [61] [111] Often it is used as the integration branch for merging changes into. [112] Since the default upstream remote is named origin, [113] the default remote branch is origin ...
Another approach is to split a branch off the trunk, implement changes in that branch and merge the changes back into the trunk when the branch has proven to be stable and working. Depending on development mode and commit policy the trunk may contain the most stable or the least stable or something-in-between version.
Source Code Control System (SCCS) [open, shared] – part of UNIX; based on interleaved deltas, can construct versions as arbitrary sets of revisions; extracting an arbitrary version takes essentially the same time and is thus more useful in environments that rely heavily on branching and merging with multiple "current" and identical versions
Merge file renames: describes whether a system can merge changes made to a file on one branch into the same file that has been renamed on another branch (or vice versa). If the same file has been renamed on both branches then there is a rename conflict that the user must resolve.
Assuming there is a trunk, merges from branches can be considered as "external" to the tree – the changes in the branch are packaged up as a patch, which is applied to HEAD (of the trunk), creating a new revision without any explicit reference to the branch, and preserving the tree structure. Thus, while the actual relations between versions ...
In version control, merging (also called integration) is a fundamental operation that reconciles changes made to a version-controlled collection of files. Most often, it is necessary when a file is modified on two independent branches and subsequently merged. The result is a single collection of files that contains both sets of changes.
