Removing Files4:14 with Jay McGavren
Removing a file from your working directory is not the same as removing it from your Git repo. In this video, we'll learn about the "git rm" command.
Removing a file from the working directory
<h1>Check out our tin medals!</h1> <p>Medallion: $10</p> <p>Ribbon: $50</p>
- We've added a
tin.htmlfile showcasing the store's new tin medals.
- If we run
git status, we'll see the file is untracked.
- So let's add it:
git add tin.html
- And then we'll commit it:
git commit -m "Add tin medals"
- But suppose we later learned that customers weren't too pleased with the new tin medals, and we've decided to drop the product.
- We can delete the file from our terminal using the
rmcommand, which stands for "remove":
Removing a file from Git
- If we run
git status, it still shows the deleted file:
$ git status # On branch master # Changes not staged for commit: # (use "git add/rm <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # deleted: tin.html # no changes added to commit (use "git add" and/or "git commit -a")
- It shows that the
tin.htmlfile has been deleted, but it shows that in the "Changes not staged for commit" section.
- We can make the deletion of
tin.htmlpart of a commit by using the
git rmis set up to work much like the plain
rmcommand, so it's much like taking our previous command and sticking
gitin front of it:
git rm tin.html
- Let's run
- ...and we'll see the deletion of
tin.htmlis listed in the "Changes to be committed" section now.
$ git status # On branch master # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # deleted: tin.html #
- Next, we can commit as usual:
git commit -m "Remove tin medals"
- Now we can run
- ...and this time it will show the working directory is clean.
$ git status # On branch master nothing to commit, working directory clean
- And if we run
ls, we'll see that the
tin.htmlfile is still gone.
- By the way, we didn't need to run
rm tin.htmlas a separate step.
git rmwill remove the file from the working directory for you, if it exists.
[MUSIC] 0:00 Previously, we've shown you how to set up a Git repository and commit files to it. 0:04 But with just the commands you know now, when you commit a file, 0:09 well you're committed. 0:12 If you decide you need to delete or 0:14 move a file, you can do it in your working directory. 0:16 But you can't do it in the Git repo. 0:18 If you staged the wrong file, we haven't shown you how to unstage it. 0:21 In these next few videos, we'll fix all that and more. 0:25 We'll show you how to delete or 0:29 move files in the get repo as well as your working directory. 0:30 You'll learn how to unstage files that you've accidentally staged. 0:34 We'll help you reset a file's contents back to the way they looked 0:37 after your last commit. 0:40 We'll show you how to bring back a file that you've accidentally deleted. 0:42 And if you decide you don't like the changes you made in the commit, 0:46 we'll show you how to undo that commit. 0:49 This is the good stuff. 0:51 In these lessons you'll begin to see the real power of Git. 0:53 Ready? 0:57 Let's get started. 0:57 We've added the tin.html file showcasing the store's new tin medals. 0:59 If we run git status, we'll see the file is untracked. 1:05 So let's add it. 1:10 Git add tin.html, and then we'll commit it, 1:11 git commit -m "Add tin medals". 1:16 And we close our editor, satisfied with a job well done. 1:23 But suppose we later learn that the customers weren't too pleased with the new 1:26 tin medals, and we've decided to drop the product. 1:30 If we run the ls command, 1:33 it will show the tin.html file here in our project directory. 1:35 We can delete the file from our terminal using the rm command, which stands for 1:39 remove, rm tin.html. 1:44 Just like ls, the rm command isn't part of Git, but 1:48 it is standard on all Unix-like systems, so it's worth learning how to use. 1:51 See the teacher's notes if you want more info. 1:56 Running ls again will show that the tin.html file is gone. 1:59 But the tin.html file is being tracked by Git. 2:03 Will deleting the file from our working directory 2:07 also delete it from the repository? 2:10 Let's try our trusty git status command to find out. 2:12 It shows that the tin.html file has been deleted, but 2:16 it shows that in the changes not staged for commit section. 2:19 Why is that? 2:23 In Git, commits don't just add or modify files, they can delete them as well. 2:25 This is important because repositories can be shared across multiple computers. 2:30 When you decide to remove a file from your project, you don't want that file to be 2:35 left sitting in your coworker's copy of the project. 2:39 You want it to be deleted from your coworker's machine, too. 2:42 Making file deletions part of a commit ensures that the copies of your Git 2:45 repository will have those deletions applied, too. 2:49 And by the way, in case you're worried about others using this feature to delete 2:53 files from your machine, there are ways to undo the deletion of a file, 2:57 even after you've committed the deletion. 3:01 We'll see one way in an upcoming video. 3:03 So how can we make the deletion of tin.html part of a commit? 3:06 The key is to use the git rm command. 3:10 Git rm is set up to work much like the plain rm command. 3:14 So it's much like taking our previous command and 3:17 sticking the word git in front of it, git rm tin.html. 3:21 Let's run git status again. 3:29 And we'll see the deletion of tin.html is listed in the changes to be 3:32 committed section now. 3:37 Next, we can commit as usual, 3:39 git commit -m, "Remove, tin medals". 3:43 Now we can run git status again, and 3:52 this time it will show that the working directory is clean. 3:54 And if we run ls, we'll see that the tin.html file is still gone. 3:59 By the way, we didn't need to run rm tin.html as a separate step. 4:03 Git rm will remove the file from the working directory for you, if it exists. 4:09
