[:en]Basic Git usages[:]

By admin, February 20, 2018

[:en]When I left the SVN world, I started to brave the new world of git. Not that new… the matter is that most system had already automated git basic usages until something weird happens during your commit/push process such as conflicts.

So, let’s start from scratch:

First commit

Approach 1 via HTTPS: Create the repo in Bitbucket or your Git tool and clone it. Note that it will create a folder. Make sure to copy the content in oyur actual working folder

If under Windows, I recommend using https://git-scm.com/download/win and using the console by clicking the mouse’s right button and git-> bash here from the directory where you want to create your project.

git clone https://user@bitbucket.org/projects/project.782.git

git add –all
git commit -am “<commit message>”
git push

or git push -f or git push -f <remote> <branch> that means

git push -f origin master

or safer: git push <remote> <branch> –force-with-lease

List ignored files

$ git ls-files . –ignored –exclude-standard –others

List untracked files

$ git ls-files . –exclude-standard –others

Git -Managing branches

Available local branches

git branch -a

Available remote branches

git branch -r

Other ways to check: git remote and git ls-remote

Git – Delete branch

https://stackoverflow.com/questions/2003505/how-do-i-delete-a-git-branch-both-locally-and-remotely

Remote (this will not ask if you have merged something or not!):

git push <remote_name> –delete <branch_name>

Local:

git branch -d branch_name
git branch -D branch_name    <– this delete regardless of already being merged

GIT checking / setting the current user and remote origin

git config user.name

git config –list

git config –global user.name “Alvin J. Alexander”

git config remote.origin.url user@email.com:repository/project.git   (e.g. the address beside SSH word at Bitbucket).

You could still change it to https if you do not have an SSH key. In this case, it will be

https://user@email.com/repository/project.git

Git – returning 1 or more commits

For git – Your branch is ahead of ‘origin/master’ by 1 commit

git reset HEAD^ –soft (Save your changes, back to last commit in HEAD)

git reset HEAD^ –hard (Discard changes, back to last commit in HEAD)

Go back one commit
git push -f origin <last_known_good_commit>:<branch_name>

git reset –hard <last_known_good_commit>
# ^^^^^^
# optional (and dangerous. Will erase existing not mapped or updated files)

revert the last commit – git revert commit_number

 

Git Rebase

 

Jenkins – dealing with credentials (more on the Jenkins post)

https://stackoverflow.com/questions/30704856/how-to-export-credentials-from-one-jenkins-instance-to-another

Jenkins – accessing github.com , bitbucket.com …

ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts

For adding the key at Bitbucket side:

ssh-keygen -t rsa -C “user.email”

or

simply ssh-keygen
