pre-task

• I consider you have installed git and git-lfs
  • then only one thing remains is preparing large binary file
• it is good to get a binary file of MB size
  • ex) a binary file of 63.4 MB

• once you get the one, copy and rename it
  • ex) some.file → test.a test.b

init-project

• make a new repository
• initialize git-lfs
• now your repository can support git-lfs

register-target

• you can choose which file should be controlled with git-lfs or git-without-lfs

• suppose you want to control the files with ".a" extension
• after the command, git-lfs constructs .gitattributes for applying

• let us check what happened
• yeap, the command worked as adding the line in .gitattributes

• copy or move the test.a into your repository
• add and commit the changes

list-of-target-and-file

• you can check the list of targets or files that are actually controlled

• copy the file as new name
• add and commit the chnages

• check out the list once again

benchmark

• there is a significant difference between git-lfs and git-without-lfs

• copy or move the test.b into your repository
• add and commit the changes, but using timer

• copy the test.a as new name
• add and commit the changes, but using timer

wrap-up

• git-lfs is provided as one option, and even you can use it with git-without-lfs
• git-lfs provides a faster version control than git-without-lfs one
• thus, I recommend you to consider git-lfs when the files are large
