在 Windows 中更改用户名后控制台中的用户名错误

Question

I had a Windows (Windows 10) local userprofile with an umlaut (ä) in it. With this I got problems while using vagrant in the Git Bash console. After some research I changed the username of my local profile (replaced the ä with ae). I also changed the name of the users folder and reinstalled vagrant after this. Everything works fine now except the fact, that the username which is shown in Git Bash is the same as before (with ä in it). But the path is correct (with ae).

I tried to change the username with git config --global user.name but this had no effect on the name displayed. I also reinstalled Git.

This is annoying (even tho it has no effect on anything). Why is that and how can I change it? Is there a way to reset it completely (besides a reinstallation)?

Because I'm not sure if I use the correct terms I mean this (the bold word) with username:

MyNameWithÄ @COMPUTERNAME MINGW64 ~

And I should also mention that I use Git only locally and I don't know if it even has something todo with Git Bash.

Kind regards

Answer 1

If you don't find the proper solution I have one ugly hack in mind.

Git-bash stores it's prompt configuration in /etc/profile.d/git-prompt.sh . When you open that file you should have this line:

PS1="$PS1"'\u@\h '             # user@host<space>

Replacing \\u\u003c/code> here with your name should do the trick. So it would be:

PS1="$PS1"'JohnDoe@\h '             # user@host<space>

In order to see the changes you need to restart git-bash.

对于 Windows 10，我发现这与管理员名称和设备名称有关（按 Window + I > Settings > System > About > Device Name）。

Answer 3

Git Bash takes the user from file /etc/passwd. To change it do:

mkpasswd > /etc/passwd

This step was necessary for me on Windows 10 because the file did not exist in that location. Administrator privileges are necessary (open Git Bash as admin).

Then change the file with your favourite editor (for instance vim). Substitute the old username with the new one.

Reopen Git Bash to see changes take effect.
