Git Commit - Saving your changes using Git Commit
Git is the most popular version control system as of 2017 and hence it is an essential part of daily workflow of majority of software developers.
Git commit command is used for saving your changes in the git repository that can be later pushed to git remote repository.
Git Commit - Saving your Changes
Git supports 3 step process for saving (committing) your changes and pushing it to central repository. These steps include:
- Git Add - Identify files that need to be committed and use git add to mark them.
- Git Commit - commit to your local git repository by providing a commit message
- Git push - Push your local commit to remote
Advantage of this multi-step process is that it allows developer to selectively commit a subset of changes. For example, if you have made changes in 5 files but only want to commit 2 files - then you 'git add' only 2 files followed by 'git commit'
Git add marks the files that need to be committed to git repository.
# add a file for commit git add file_name1 git add file_name2 # see all files marked for commit git status
Sometime, instead of typing individual files we want to add all files in a directory. One can use following for this:
# add all changes in a directory git add directory_name
# commit all changes added using git add git commit # opens up text editor for commit message # short cut: provide commit message on command line git commit -m 'commit msg'
Once you commit a change to your local repository, you need to push it to central repository. Otherwise your changes will not be visible to your colleagues.
# push local committed changes to remote branch git push origin branch_name
