Git: basic tag commands

To get the repository’s tags issue:

$ git fetch --tags [branch_name]

To add a tag to the top commit:

$ git tag -a

Note: this will open an editor screen where you can insert a description message (similar to a commit)

To add a tag to a specific commit:

$ git tag -a [tag_name] [commit_hash]

To push a tag to remote:

$ git push [repo_name] --tags  # for all tags
$ git push [repo_name] [tag_name] # for a single tag named 'tag_name'

To merge a tagged commit:

$ git merge [tag_name]

Git: add a remote repository

In case you need to work with more than one remote repositories, chances are you need to add one of them (origin comes as a default).

$ git remote add remote_name https://github.com/user/repo.git 

Choose the remote_name as you wish and grab the repo URL from github.

Create patches with git format-patch

Git has a wonderful tool that allows you to create patches of the commits in the tree of your project: git format-patch.

Usage:

 $ git format-patch [<options>] [<since> | <revision-range>]

More information can be seen via man page:

$ git format-patch -h

or

$ man git format-patch

For example:

$ git format-patch -N

This command generates one .patch file for each of the N commits on the top of your tree. Example:

$ git format-patch -1

Generates a .patch file for the commit on the top of your tree. Increase the number to get one file per commit (for the top 3 commits, use ‘-3’).

To apply the patch, use

$ git am [your-patch].patch

Cheers!

To ssh://dkreling@:/RobotFramework.git

Git: selecting remote repository on git

I recently started to work with two remote repositories on git, and then faced a probably common scenario: check the state of each repository (say ‘origin‘ and ‘vertiv‘).

A 20 minute search provided me the best solution:

$ git branch -u [remote-repo]/[branch]

For example:

git_st_remote

In this case, origin/master is ahead of vertiv/master by 2 commits, and my local is sync’ed with vertiv/master.

The docs read:

-u <upstream>, –set-upstream-to=<upstream>
Set up <branchname>’s tracking information so <upstream> is considered <branchname>’s upstream branch. If no <branchname> is
specified, then it defaults to the current branch.

Cheers!
