When vim edits certain system files, the contents of the files are displayed in different colors in the directory of the environment variables specified by the system, so that they can be easily identified and modified.
such as:/etc/passwd and copy to/TMP/PASSWD configuration file is not the same, because the variable environment changes will not show multiple colors
