How to go to the latest commit in a branch?

Question

git

What is the console command to update the current versions of files in a branch to the latest commit?
The documentation suggests using the git pull command - download all changes from update the files to the latest version.
But the problem is that I'm using jgit - it's a script for Solaris (there are no official packages for git), and it doesn't have such a command.
There is a fetch command - but this is only for downloading from a remote change repository.
There is a reset --hard command - but for this you need to know the hash of the last commit.
What other commands are there in git besides pull?

Answer 1

git fetch
git checkout <branch>
git merge origin/<branch>

Answer 2

you can try git checkout HEAD, or do git logit, we will see the last commit, take the first 4 symbols of its cache - and then enter git checkout 1s24, where 1s24 are the same cache symbols

Answer 3

A more universal way that allows you to go to any commit that is located in the branch later than the current one:
Display all commits in the branch, including those that were later than the current one:
And then just go to the last commit by hash:
And if it is the last one, then so (branch_name - branch name)
git checkout branch_name
