不同类型的ulimit配置解释

我正在设置几个 ulimit（系统是 rhel 7.5），但我找不到有关type.从内部/etc/security/limits.conf我得到该类型可以获取两个值，而在配置示例中该文件包含有 3 个值：

  1. 柔软的
  2. 难的
  3. -（破折号）

在下面文件的示例中@学生有一种类型-。

问题何时-（破折号）用来？

    ....
    #<type> can have the two values:
    #        - "soft" for enforcing the soft limits
    #        - "hard" for enforcing hard limits
    .....
    #<domain>      <type>  <item>         <value>
    #*               soft    core            0
    #*               hard    rss             10000
    #@student        hard    nproc           20
    #@faculty        soft    nproc           20
    #@faculty        hard    nproc           50
    #ftp             hard    nproc           0
    #@student        -       maxlogins       4
    .....

您将在以下位置找到答案人限制.conf

<type>
hard
for enforcing hard resource limits. These limits are set by the superuser and enforced by the Kernel. The user cannot raise his requirement of system resources above such values.
soft
for enforcing soft resource limits. These limits are ones that the user can move up or down within the permitted range by any pre-existing hard limits. The values specified with this token can be thought of as default values, for normal system usage.
-
for enforcing both soft and hard resource limits together.
Note, if you specify a type of '-' but neglect to supply the item and value fields then the module will never enforce any limits on the specified user/group etc. .
