Git retrieve a single file from old commit

Many times we wanted to retrieve a single file from old commit, below is the simple command to get the job done.

git checkout <commit_hash_value> <file_path_to_retrive>

We can also use HEAD reference in place of hash value:

• HEAD  will get file from last commit
• HEAD^ : Last Commit - 1
• HEAD^^ : Last Commit - 2
• HEAD~10 : 10 Commits behind the git HEAD
