 Symbolic links to the new bash from brew might not get updated. There's one in /usr/local/bin/bash to update manually.
+First, check which shell you're in. And check which would be run. And check which are symlinks.
+<code>
+$ echo "$0"
+/bin/bash
+$ which bash
+/opt/homebrew/bin/bash
+$ which -a bash | xargs ls -l

+Then, if there's a broken symlink, fix it.
 <code>
 $ sudo rm /usr/local/bin/bash
-bash: __git_ps1: command not found
+$ sudo ln -s /opt/homebrew/bin/bash /usr/local/bin/bash
-$ sudo ln -s /opt/homebrew/Cellar/bash/5.3.9/bin/bash /usr/local/bin/bash
