I have a question that I am sure is very simple but which I can't find the answer for. I am an animator working on the Unreal Engine 4 and using Source Control, Bitbucket and Source Tree to collaborate on a current project. My coding expertise draws the line at php and terminal scares me to no end. I've done plenty of research on reducing git repository sizes with mild success.
The Case: I've run out of space on my Repository (probably because UE4 saves a million auto save files every time I use it) and need to delete some files.
What I've found:
Evidently, files on a git repository are not meant to be deleted with ease (For safety perhaps). There doesn't appear to be a way to just go to the repository highlight some stuff and hit delete. Thus far, however, I've found two promising leads right here in StackOverflow.
What I'd like to know:
From what I've read, BFG seems to be the fastest and most efficient solution to repository reduction out there. Is this an accurate assessment?
There are many resources online on how to use the tool, ( such as this one ) but none that answer my (very basic, I imagine) question. After I download it, what do I do with the file? Do I just double click it? Does the .jar file need to be in a specific place? Must I run it and then follow the instructions?
What I've tried:
I double clicked it and it seems to have run but it had no effect.
I tried running the code snippets from several walkthrough articles (including the one I've linked to above) through terminal using source tree's terminal button and replacing all the placeholder urls with mine on the copied code, but any snippet that contains the words bfg.jar fails. All the code I've found online for the tool returns a "command not found" message in terminal, which is not surprising since the tool is just sitting in my downloads folder.
I've looked at "working with .jar files" articles but all I could find seems to be more interested in coding such files than running them, and so, I am at a loss.
Thank you in advance for any and all help.
Cheers, Omar
Things that help when you are new to the terminal, that you will almost never find, in instructions for programs that run in a terminal:
bfg-1.12.15.jar
. Either you rename the file to bfg.jar (but you might not want to if later you want to know the version you have), or you type it in just like that. ~
. So, I put the command like this: java -jar ~/bfg-1.12.15.jar
. You can specify any path by starting from the root folder and indicating folders nested within it with a forward slash, like ~/Music/Funk/James_Brown/get-on-up.mp3
, for instance. The program will run from anywhere if the OS knows where to find it. cd
, then you specify the path as shown above. BFG requires minimum Java 7 since v1.12.5. There is no UI, so you need to become comfortable running it from the command-line, but there is sufficient documentation available to succeed on the website . Double-clicking the jar file won't get you anywhere.
Once you have java
version 7 running from a command-prompt, just run:
$ java -jar bfg.jar
... to generate the usage/options, or refer to the website.
To answer your question 1), within the restrictions imposed by its approach, BFG is indeed the fastest tool around that I am aware of for rewriting history whilst removing files.
转到复制此bfg.jar
(新版本的名称将不同)的目录,然后运行以下命令:
java -jar bfg-1.13.0.jar --strip-blobs-bigger-than 50M <Cloned GitRepo Path>
1) $ java -jar bfg.jar --replace-text replacements.txt my-repo.git Once we run this command will it automatically commit to GitHub or we would require to explicitly commit it post changes. Will it effect on all the branches like Develop / Master ?
2) $ java -jar bfg.jar Can we run this Jar from any location or any particular location we should download it.
