Try `git reset --patch filename`; this should do the opposite of `git add --patch`, according to the [documentation](http://git-scm.com/docs/git-reset). The short form `-p` also works for both commands.

`git gui` has a decent GUI to interactively stage or unstage hunks or lines. There are prettier/better GUI clients, but `git gui` is lightweight, built-in, and cross platform (lin, win, mac).

https://git-scm.com/docs/git-gui

Simply right click on a hunk to stage/unstage. For lines, highlight the lines first, then right click.

[GitX][1] has a nice UI for unstaging chunks of a file:

The official client hasn&#39;t been maintained in a while, but [a fork over at GitHub][3] with more features is popular in some circles. ([blog post about it][4])

We used the link:

...to share a particular page. However, Facebook Sharer uses the cached version of the images and the title. Is there a way to quickly clear the Facebook cache or how long do we have to wait until the data gets updated?

I placed `&lt;link rel=&#39;image_src&#39; href=&#39;[preview image]&#39; /&gt;` in between the &lt;head&gt;&lt;/head&gt; tags.




How to clear Facebook Sharer cache?

I am animating a `CALayer` along a `CGPath` (QuadCurve) quite nicely in iOS. But I&#39;d like to use a more interesting easing function than the few [provided][1] by Apple (EaseIn/EaseOut etc). For instance, a bounce or elastic function. 

These things are possible to do with MediaTimingFunction (bezier):

![enter image description here][2]

But I&#39;d like to create **timing functions** that are more complex. Problem is that media timing seems to require a cubic bezier which is not powerful enough to create these effects:

[![enter image description here][4]][4]  
&lt;sub&gt;(source: [sparrow-framework.org](http://wiki.sparrow-framework.org/_media/manual/transitions.png))&lt;/sub&gt;  


The [code][3] to create the above is simple enough in other frameworks, which makes this very frustrating. Note that the curves are mapping input time to output time (T-t curve) and not time-position curves. For instance, *easeOutBounce(T) = t* returns a new *t*. Then that *t* is used to plot the movement (or whatever property we should animate).

*So, I&#39;d like to create a complex custom `CAMediaTimingFunction` but I have no clue how to do that, or if it&#39;s even possible? Are there any alternatives?*

**EDIT:**

Here is a concrete example in to steps. Very educational :)

1. I want to animate an object along a line from point *a* to *b*, but I want it to &quot;bounce&quot; its movement along the line using the easeOutBounce curve above. This means it will follow the exact line from *a* to *b*, but will accelerate and decelerate in a more complex way than what is possible using the current bezier-based CAMediaTimingFunction. 

2. Lets make that line any arbitrary curve movement specified with CGPath. It should still move along that curve, but it should accelerate and decelerate the same way as in the line example.

In theory I think it should work like this:

Lets describe the movement curve as a keyframe animation *move(t) = p*, where *t* is time [0..1], *p* is position calculated at time *t*. So *move(0)* returns the position at the start of curve, *move(0.5)* the exact middle and *move(1)* at end. Using a an timing function *time(T) = t* to provide the *t* values for *move* should give me what I want. For a bouncing effect, the timing function should return the same *t* values for *time(0.8)* and *time(0.8)* (just an example). Just replace the timing function to get a different effect.

(Yes, it&#39;s possible to do line-bouncing by creating and joining four line segments which goes back and forth, but that shouldn&#39;t be necessary. After all, it&#39;s just a simple linear function which maps *time* values to positions.)


I hope I&#39;m making sense here.

How to create custom easing function with Core Animation?

In git, if I have a couple of hunks from the same file staged in my index, how can I interactively unstage one of them?

Is there any alternative to unstaging the entire file, and then re-staging the hunks I want to keep, or manually undoing the changes to the working copy, and then interactively adding those undone changes?

I want to get a list of all the branches in a Git repository with the &quot;freshest&quot; branches at the top, where the &quot;freshest&quot; branch is the one that&#39;s been committed to most recently (and is, therefore, more likely to be one I want to pay attention to).

Is there a way I can use Git to either (a) sort the list of branches by latest commit, or (b) get a list of branches together with each one&#39;s last-commit date, in some kind of machine-readable format?

Worst case, I could always run `git branch` to get a list of all the branches, parse its output, and then `git log -n 1 branchname --format=format:%ci` for each one, to get each branch&#39;s commit date. But this will run on a Windows box, where spinning up a new process is relatively expensive, so launching the Git executable once per branch could get slow if there are a lot of branches. Is there a way to do all this with a single command?

I have cloned a remote Git repository to my laptop, then I wanted to add a tag so I ran

    git tag mytag master

When I run `git tag` on my laptop the tag `mytag` is shown. I then want to push this to the remote repository so I have this tag on all my clients, so I run `git push` but I got the message:

&gt; Everything up-to-date

And if I go to my desktop and run `git pull` and then `git tag` no tags are shown. 

I have also tried to do a minor change on a file in the project, then push it to the server. After that I could pull the change from the server to my Desktop computer, but there&#39;s still no tag when running `git tag` on my desktop computer.

How can I push my tag to the remote repository so that all client computers can see it?

I have been working with git for just over a month. Indeed I have used reset for the first time only yesterday, but the soft reset still doesn&#39;t make much sense to me.

I understand I can use the soft reset to edit a commit without altering the index or the working directory, as I would with `git commit --amend`. 

Are these two commands really the same (`reset --soft` vs `commit --amend`)? Any reason to use one or the other in practical terms? And more importantly, are there any other uses for `reset --soft` apart from amending a commit?

Practical uses of git reset --soft?

I ran &quot;git status&quot; and listed below are some files that were modified/or under the heading &quot;changes not staged for commit&quot;.
It also listed some untracked files that I want to ignore (I have a &quot;.gitignore&quot; file in these directories).

I want to put the modified files in staging so I can commit them.  When I ran &quot;git add .&quot;, it added the modified files AND the files I want to ignore to staging.

How do I add only the modified files and ignore the untracked files if presented with the git status below.

Also, are my &quot;.gitignore&quot; files working properly?


    $ git status
    # On branch addLocation
    # Changes not staged for commit:
    #   (use &quot;git add &lt;file&gt;...&quot; to update what will be committed)
    #   (use &quot;git checkout -- &lt;file&gt;...&quot; to discard changes in working directory)
    #
    #       modified:   someProject/path/domain/viewer/LocationDO.java
    #       modified:   someProject/path/service/ld/LdService.java
    #       modified:   someProject/path/service/ld/LdServiceImpl.java
    #       modified:   someProject/path/web/jsf/viewer/LocationFormAction.java
    #       modified:   someProject/war/WEB-INF/classes/message/viewer/viewer.properties
    #       modified:   someProject/war/page/viewer/searchForm.xhtml
    #
    # Untracked files:
    #   (use &quot;git add &lt;file&gt;...&quot; to include in what will be committed)
    #
    #       .metadata/
    #       someProject/build/
    no changes added to commit (use &quot;git add&quot; and/or &quot;git commit -a&quot;)



git add only modified changes and ignore untracked files

If you want to move a commit to the staging area - that is uncommit it and move all of the changes which were in it into the staging area (effectively putting the branch in the state that it would have been in prior to the commit) - how do you do it? Or is it something that you can&#39;t do?

The closest that I know how to do is to copy all of the files that were changed in the commit to somewhere else, reset the branch to the commit before the commit that you&#39;re trying to move into the staging area, move all of the copied files back into the repository, and then add them to the staging area. It works, but it&#39;s not exactly a nice solution. What I&#39;d like to be able to do is just undo the commit and move its changing into the staging area. Can it be done? And if so, how?

How do you move a commit to the staging area in git?

To use git effectively (and as intended) I make small atomic commits, while I do have longer sessions where I do change not only one thing. Thus, I make heavy use of `git add -p`. This doesn&#39;t work for completely new files, though, because I tend to forget them later on.

What I want to do is, tell `git` that there *is* a new file, I want it to track, but *not stage it*:

Example: Running `git status` produces:

    # On branch my-current-branch
    # Your branch is ahead of &#39;origin/my-current-branch&#39; by 2 commits.
    #
    # Changes to be committed:
    #
    &lt;&lt;STAGED SECTION&gt;&gt; // A
    #
    # Changes not staged for commit:
    #   (use &quot;git add &lt;file&gt;...&quot; to update what will be committed)
    #   (use &quot;git checkout -- &lt;file&gt;...&quot; to discard changes in working directory)
    #
    &lt;&lt;UNSTAGED-YET-KNOWN SECTION&gt;&gt; // B
    #
    # Untracked files:
    #   (use &quot;git add &lt;file&gt;...&quot; to include in what will be committed)
    #
    &lt;&lt;UNKNOWN SECTION&gt;&gt; // C

If I have a file `foo` in the C section, and I say `git add foo` it will go to the A section. If I say `git add -N foo` it will go to both A and B. However, that would mean it would be included in the next commit, at least as the fact that there is a new file.

I want it to go in section B exclusively, such that I can later add it to A with `git add -p` or `git add foo` (or whatever).

## Edit
Regarding the `add -N` solution, this doesn&#39;t work because if I try to commit after having said `add -N` and *not* having added it properly, git complains because it doesn&#39;t know how to handle empty files:

    foo: not added yet
    error: Error building trees
