您可以使用

systemctl list-units --type target

这会返回类似的东西，

UNIT                                       LOAD   ACTIVE SUB    DESCRIPTION        >

您可以使用：

systemctl list-unit-files --type target --all

  • list-unit-files：列出单元文件
  • --type target：仅显示目标单位
  • --all：列出所有单元文件，无论其状态如何

还要列出用户目标：

systemctl list-unit-files --type target --all --user
