How can I use uid replace username ?

If I got several long usernames(e.g. bioinfo-01, bioinfo-02, bioinfo-03, ...), I cannot recognize which user is using the current process, so is there any way to use uid replace username? Thank you.

The issue mentions no files, tests, or entry points. Start by locating where process owners are displayed in bashtop, then check how the current username value is obtained and rendered. Done means the process list shows a user's UID instead of the username, with existing process display behavior preserved.
