diff git code example

Example 1: git diff of a file between two commits

git diff <branch_hash> <other_branch_hash> -- <file_path>

Example 2: make diff git as commit

A simple way to do it is:

create and checkout branch tmp at branch_a (git branch tmp branch_a && git checkout tmp)
git reset --soft branch_b
git commit
that commit must have all the diff

Example 3: git diff of a file

git diff file-name

#you can also add an alias on Mac
alias gd="git diff"
alias add_alias="code ~/.zshrc" #open the file in vscode
