How to get whole git history afterwards "git clone --depth=1"?

Question

One of my git repo was huge, containing huge assets to previous commits.

Somehow I was able to clone repo(made runnable) using git clone <repo> --depth=1.

I want to get all the previous commits on same local repo.

Thank You.

git pull --unshallow should do it.

From (git-scm)

--unshallow

If the source repository is complete, convert a shallow repository to a >complete one, removing all the limitations imposed by shallow repositories.

If the source repository is shallow, fetch as much as possible so that the >current repository has the same history as the source repository.

pull's --depth, --deepen= and --shallow-since may also be relevant.

From (git-scm)

--depth=<depth>

Limit fetching to the specified number of commits from the tip of each remote branch history. If fetching to a shallow repository created by git clone with --depth= option (see git-clone[1]), deepen or shorten the history to the specified number of commits. Tags for the deepened commits are not fetched.

--deepen=<depth>

Similar to --depth, except it specifies the number of commits from the >current shallow boundary instead of from the tip of each remote branch history.

--shallow-since=<date>

Deepen or shorten the history of a shallow repository to include all reachable commits after <date>.

git guru @torek points out the following:

Be aware that a clone made with --depth is also, by default, a single-branch clone. To make it a full clone you will need to undo this single branch effect.

How to do it is shown at How do I "undo" a --single-branch clone?.
