What are the differences between .gitignore and .gitkeep?

What are the differences between .gitignor开发者_StackOverflow社区e and .gitkeep? Are they the same thing with a different name, or do they both serve a different function?

I don't seem to be able to find much documentation on .gitkeep.

.gitkeep isn’t documented, because it’s not a feature of Git.

Git cannot add a completely empty directory. People who want to track empty directories in Git have created the convention of putting files called .gitkeep in these directories. The file could be called anything; Git assigns no special significance to this name.

There is a competing convention of adding a .gitignore file to the empty directories to get them tracked, but some people see this as confusing since the goal is to keep the empty directories, not ignore them; .gitignore is also used to list files that should be ignored by Git when looking for untracked files.

.gitkeep is just a placeholder. A dummy file, so Git will not forget about the directory, since Git tracks only files.

---

If you want an empty directory and make sure it stays 'clean' for Git, create a .gitignore containing the following lines within:

# .gitignore sample
# Ignore all files in this dir...
*

# ... except for this one.
!.gitignore

If you desire to have only one type of files being visible to Git, here is an example how to filter everything out, except .gitignore and all .txt files:

# .gitignore to keep just .txt files
# Filter everything...
*

# ... except the .gitignore...
!.gitignore

# ... and all text files.
!*.txt

.gitignore

is a text file comprising a list of files in your directory that git will ignore or not add/update in the repository.

.gitkeep

Since Git removes or doesn't add empty directories to a repository, .gitkeep is sort of a hack (I don't think it's officially named as a part of Git) to keep empty directories in the repository.

Just do a touch /path/to/emptydirectory/.gitkeep to add the file, and Git will now be able to maintain this directory in the repository.

---

Many people prefer to use just .keep since the convention has nothing to do with git.

---

This is not an answer to the original question "What are the differences between .gitignore and .gitkeep?" but posting here to help people to keep track of empty dir in a simple fashion. To track empty directory and knowling that .gitkeep is not official part of git,

just add a empty (with no content) .gitignore file in it.

So for e.g. if you have /project/content/posts and sometimes posts directory might be empty then create empty file /project/content/posts/.gitignore with no content to track that directory and its future files in git.

---

A file .gitignore is used to tell Git which files and folders it should ignore. Often, these files are build artefacts, temporary files, or other types of files that don't belong in the repository. Git will disregard any directory or file that fits a pattern in the .gitignore file.

Example:

# Ignore .DS_Store files
.DS_Store

# Ignore build artifacts
build/

# Ignore log files
*.log

---

Contrarily, a .gitkeep file is utilised in Git to maintain a directory that would otherwise be empty. Git does not by default track empty folders, thus you must add a .gitkeep file to that directory if you wish to keep it in your repository. The filename is more significant than the file's actual contents.

Example of .gitkeep file

# This file is used to keep the directory empty in Git

---

In conclusion. The .gitignore command is used to tell Git which files and folders to ignore. To maintain a Git directory that would otherwise be empty, use .gitkeep. They are distinct from one another and have different functions.
