Topic: git clone

Recall

What is git clone?

What all protocols does git clone support?

Notes

• Usage: git clone <repo_name> <optional_directory_name>
• Clones the full data that the server has, with each and every version.
• <repo_name> can use https or git or user@server protocol. Eg: https://github.com/libgit2/libgit2

<aside> 📌 SUMMARY: git clone makes a full copy of the data with all its versions and checks out on the latest version.

Topic: Checking three states of files

Recall

How to check the staged/committed status of files

Notes

• git status tells
  • the state of files: staged/committed
  • the branch we are on
  • If we have switched from same branch on the server.
• add -sor --short to git status as an argument to get concise and simplified status output.

<aside> 📌 SUMMARY: git status command helps getting the status of untracked files and the current branch.

Topic: Ignoring files

Recall

How to protect some files from being staged or being mentioned untracked by git?

What file pattern standard does gitignore follow?

Notes

• Create a file .gitignore that contains class of files you don’t want to add to git or show as untracked.

$ cat .gitignore
# File extensions ending in o or a.
*.[oa] 
# File name ending in ~
*~ 
# ignore all .a files
*.a
# but do track lib.a, even though you're ignoring .a files above
!lib.a
# only ignore the TODO file in the current directory, not subdir/TODO
/TODO
# ignore all files in any directory named build
build/
# ignore doc/notes.txt, but not doc/server/arch.txt
doc/*.txt
# ignore all .pdf files in the doc/ directory and any of its subdirectories
doc/**/*.pdf

• Rules to create file pattern:
  • Blank lines or lines starting with # are ignored.
  • Standard glob patterns work, and will be applied recursively throughout the entire working tree.
  • You can start patterns with a forward slash (/) to avoid recursivity.
  • You can end patterns with a forward slash (/) to specify a directory.
  • You can negate a pattern by starting it with an exclamation point (!).

<aside> 📌 SUMMARY: To avoid staging files or being mentioned as untracked by git we mention those files as their name or using pattern in a file .gitignore
