Amending the most recent commit message
git commit --amend
will open your editor, allowing you to change the commit message of the most recent commit. Additionally, you can set the commit message directly in the command line with:
git commit --amend -m "New commit message"
…however, this can make multi-line commit messages or small corrections more cumbersome to enter.
Make sure you don't have any working copy changes staged before doing this or they will get committed too. (Unstaged changes will not get committed.)
Changing the message of a commit that you've already pushed to your remote branch
If you've already pushed your commit up to your remote branch, then - after amending your commit locally (as described above) - you'll also need to force push the commit with:
git push <remote> <branch> --force
# Or
git push <remote> <branch> -f
Warning: force-pushing will overwrite the remote branch with the state of your local one. If there are commits on the remote branch that you don't have in your local branch, you will lose those commits.
Warning: be cautious about amending commits that you have already shared with other people. Amending commits essentially rewrites them to have different SHA IDs, which poses a problem if other people have copies of the old commit that you've rewritten. Anyone who has a copy of the old commit will need to synchronize their work with your newly re-written commit, which can sometimes be difficult, so make sure you coordinate with others when attempting to rewrite shared commit history, or just avoid rewriting shared commits altogether.
Perform an interactive rebase
Another option is to use interactive rebase.
This allows you to edit any message you want to update even if it's not the latest message.
In order to do a Git squash, follow these steps:
// n is the number of commits up to the last commit you want to be able to edit
git rebase -i HEAD~n
Once you squash your commits - choose the e/r
for editing the message:
Important note about interactive rebase
When you use git rebase -i HEAD~n
there can be more than n commits. Git will "collect" all the commits in the last n commits, and if there was a merge somewhere in between that range you will see all the commits as well, so the outcome will be n + .
Good tip:
If you have to do it for more than a single branch and you might face conflicts when amending the content, set up git rerere
and let Git resolve those conflicts automatically for you.

Option A:
git clone git@github.com:whatever folder-name
Ergo, for right here
use:
git clone git@github.com:whatever .
Option B:
Move the .git
folder, too. Note that the .git
folder is hidden in most graphical file explorers, so be sure to show hidden files.
mv /where/it/is/right/now/* /where/I/want/it/
mv /where/it/is/right/now/.* /where/I/want/it/
The first line grabs all normal files, the second line grabs dot-files. It is also possibe to do it in one line by enabling dotglob (i.e. shopt -s dotglob
) but that is probably a bad solution if you are asking the question this answer answers.
Better yet:
Keep your working copy somewhere else, and create a symbolic link. Like this:
ln -s /where/it/is/right/now /the/path/I/want/to/use
For your case this would be something like:
ln -sfn /opt/projectA/prod/public /httpdocs/public
Which easily could be changed to test if you wanted it, i.e.:
ln -sfn /opt/projectA/test/public /httpdocs/public
without moving files around. Added -fn
in case someone is copying these lines (-f
is force, -n
avoid some often unwanted interactions with already and non-existing links).
If you just want it to work, use Option A, if someone else is going to look at what you have done, use Option C.
Best Answer
Adding a pull request to an existing upstream issue is easy assuming you forked using the normal github means.
Simply reference the issue in your commit message using any of the supported keywords:
For example: "this commit fixes #116"
The text referencing the issue does not need to appear in the subject line of your commit.
Push your commit to your github repo and the pull request will be automatically appended to the issue.
Note: While it is not required, it is strongly recommended that you commit anything that will be part of a pull request to a separate branch specific to that issue, because future commits on that branch will be appended to the pull request (automatically by github). So, if you didn't make a separate branch, left it on master, and then kept developing, then all your unrelated commits to master would get appended to your pull request.
