The “local user” inspector is Windows only, so not useful for UNIX/Linux.
There are no built-in inspector, so we will have to go directly to the OS.

preceding texts of firsts “:” of lines whose (preceding text of first “:” of following text of first “” of it) as integer > 999) of file “/etc/passwd”
