Useful Git Commands

I'm going to hold a Git study session on November 14th. This gist is just a personal memo.

Commands

• git diff --cached use this everytime before commiting in order to avoid tiny careless mistakes.
• git diff --name-only | xargs grep 'word-you-want-to-search' grep "word-you-want-to-search" among changed files.
• git log -10 --graph | less show quick history.
• git stash and (git stash pop or git stash apply) you should use them to switch branches.
• git rebase -i to edit history.

Exercises

• See cached file and none-cached files using git reset <filename> and git add <filename>. Use git diff, git diff --cached and git status. When a staged file is deleted, its cache would be still there. Do rm <filename> without using git rm. And then do git reset HEAD <filename>. The file would go away.
• Specifing a directory would point to all files in the directory. Use git add, git reset HEAD, git diff to see the effect.
