How to get parent of specific commit in Git?

Question

I have commit number. I would like to get previous commit number(parent). I need commits from current branch.

Answer 1

If trying to get all parents and using revision parameter syntax, you may try using log subcommand with --no-walk option.

An example, if we have the following:

$ git --oneline --graph
*   A
|\
| * B
| * C
| * D
* |   E

In this example, I'll use ^@ to get all parents and the --no-walk option to show only the parents and not their ancestors.

$ git log --no-walk A^@
commit B
    ........

commit E
    ........

Check out git rev-parse for more detail about revision parameter.
