GIT is a Distributed Version Control System (DVCS) and Source Code Management System (SCMS) which can track changes to a file and lets you revert back to any particular change. It can also handle small and large projects with efficiency and speed.
GIT is recommended to be used because of its following advantages:
It takes the current state of working directory and index and pushes into the stack for later and returns to you the clean working directory.GIT stash will help you in the instances where you are working on a project and you want to switch the branches to work on something else.
GIT stash drop:
When you are done and want to eliminate the stashed item from the list, then running the GIT “stash drop” command will remove the last added stash item by default and can also remove the specific item if any argument is included or mentioned.
The commit object contains the following components
The GIT Bisect command is used to find the commit that has introduced a bug by using binary search.
Purpose of GIT Bisect command
The command uses a binary search algorithm to find which commit in the project’s history has introduced a bug.
Before the bug is introduced into the commit, the commit is referred as “good”; after the introduction of the bug, it is referred as “bad”.
Then the command used picks a commit between those endpoints and asks what kind of commit is it. The process continues till it finds the exact commit that introduced the change.
The branching in GIT is done to allow the user to create their own branch and toggle between those branches. It will allow the user to go to the previous work keeping the current work intact.
GIT fetch : It downloads only the new data from the remote repository and does not integrate any of the downloaded data into your working files. Providing a view of the data is all it does.
GIT pull: It downloads as well as merges the data from the remote repository into the local working files. This may also lead to merging conflicts if the user’s local changes are not yet committed. Using the “GIT stash” command hides the local changes.
