Random git tips
This is going to be a small cheatsheet for random
git commands that I find myself using most of the time. I am not going to get into the detail of any of the commands, if you would like to know more about any of them I would recommend going through git docs.
Saving the credentials
Sometimes you might get offended by the git prompting for the credentials again and again i.e. whenever you are
pushing to the repository.
You can make
git to stop asking for the credentials by either of the two ways (are there more?!) stated below
- You may add an SSH key so that
gitwill trust your PC and won’t ask for the credentials.
- Use git credential helper:
git config credential.helper store
By using this command, it would cache the credentials and you won’t have to type them again. However, there might be some security concerns involved as this method stores them in plain text form. Have a look at this stackoverflow question for
osxkeychain and some alternative ways to use this or visit any of these
Rebasing the commits
git rebase is really powerful however I mostly find myself using it to rebase the commits in order to have a clean history. Here is how you rebase the commits i.e. merge the minor commits into one meaningful commit.
git rebase -i xxxxx
xxxxx is the hash of the commit immediately below the commit message till which you want to rebase the commits.
Renaming a branch
You can do the following to rename a branch
git branch -m old_branch_name new_branch_name
Also, if you want to rename the branch which you are currently on, you can do the following
git branch -m new_branch_name
Detached head problem
Sometimes you might get the problem of detached head. Most common cause for this to occur is, you checkout some specific commit and you start getting this detached head warning since you are not any branch. So how do you solve this?! You simply checkout the branch you were on. For example if you were doing some work upon the
develop branch, when you started getting this warning, do
git checkout develop
If you forget about the branch you were on, you may simply
checkout some (any) branch and the problem will be solved.
Checking the log
This one is pretty straight forward. You simply do:
This will give you the detailed versoin. However, if you just want to have a look at the commit messages (and hashes), simply do the following:
git log --oneline
Resetting the changes
If you want to get all the staged changes back i.e. revert the
git add ., you can do the following
git reset HEAD
If you want to revert all the changes since the last commit do the following
git reset --hard HEAD
git clean -fd which will remove all the untracked files.
That SSL Verification Error
Sometimes, you might get SSL certificate error when cloning, pulling or pushing. The simplest way to make it go away is turn off the SSL verification i.e.
git config --global http.sslVerify false
Ignore the mode changes
Sometimes, for some odd reason, you might want to have different file modes on your local repository while having different file modes on the online version. Or you might have accidentally done
chmod -R 777, like I did, which you do not want to push over to the server, you can simply ask git to ignore any kind of file mode changes:
git config core.fileMode false
Get the last commit with message regex
If you want to find some commit having a specific message you may use the
git show :/regex command where
regex is the regular expression of the message. For example, if you want to find the containing the word
functionality, you may try the following:
git show :/fix
That’s about it. There is alot more to tell and there are many that I must have missed but stated are the ones that I find myself using most of the time. Do you have any of your own? feel free to share them by using the comments section below.
