git - How can I show the hash IDs of all the commits?

Question

This from https://stackoverflow.com/a/54314490/10082400 can show only the hash IDs of selected commits

git rev-list --ancestry-path $ahash..branch1

This can show all kinds of information about all the commits:

git log --all

How can I show only the hash IDs of all the commits? Thanks.

You can use the --all option to rev-list:

> git rev-list --all

...

You can also use the --pretty flag to control exactly what git log outputs, although in this case my abbrev setting shortened the sha1's -- --no-abbrev would make it output the same as git rev-list --all:

> git log --pretty=%h --all
