I'm reading Pro Git book and I learn some cool stuff. I don't know if I'm going to use these, so I'm not sure if it's a good idea to make seperate files for all the commands. But they are just so cool that I want to note it somewhere. So this file is created specifically for this purpose. If I ever need a command from this file, I will move it to their own file.
- Limiting the logs since/until some time, or from specific author
If you to know which changes are made since some time, use --since option like:
git log --since=2.weeks
or until some time
git log --until="20-01-2020"
These commands works with lots of formats, you can specify a specific date like "2008-01-15", or a relative date such as "2 years 1 day 3 minutes ago"
The --author option allows you to filter on a specific author
git log --author="Asocia"
- Getting the logs for a specific string
Another really helpful filter is the -S option (colloquially referred to as Git’s “pickaxe” option), which takes a string and shows only those commits that changed the number of occurrences of that string. For instance, if you wanted to find the last commit that added or removed a reference to a specific function, you could call:
git log -S function_name
- Adding remotes and fetching them
We’ve mentioned and given some demonstrations of how the git clone command implicitly adds the origin remote for you. Here’s how to add a new remote explicitly. To add a new remote Git repository as a shortname you can reference easily, run git remote add :
$ git remote -v
$ git remote add pb https://github.com/paulboone/ticgit
$ git remote -v
$ git fetch pb
Paul’s master branch is now accessible locally as pb/master — you can merge it into one of your branches, or you can check out a local branch at that point if you want to inspect it.
- Using git switch to create and checkout branches
From Git version 2.23 onwards you can use git switch instead of git checkout to:
- Switch to an existing branch: git switch testing-branch.
- Create a new branch and switch to it: git switch -c new-branch. The -c flag stands for create, you can also use the full flag: --create.
- Return to your previously checked out branch: git switch -.
- Renaming branches
Suppose you have a branch that is called bad-branch-name and you want to change it to corrected-branch-name, while keeping all history. You also want to change the branch name on the remote (GitHub, GitLab, other server). How do you do this? Rename the branch locally with the git branch --move command:
git branch --move bad-branch-name corrected-branch-name
This replaces your bad-branch-name with corrected-branch-name, but this change is only local for now. To let others see the corrected branch on the remote, push it:
git push --set-upstream origin corrected-branch-name
To delete the old branch name:
git push origin --delete bad-branch-name
