module

module概述

module 是 *nix 系统上加载/管理模块的命令。

module安装

大多数发行版上并未默认安装，运行该命令则会出现如下错误：

module: command not found。

需手动执行安装命令，安装软件包 environment-modules：

1. For CentOS：

   [root@localhost ~]# dnf install environment-modules

2. For Ubuntu：

   [miya@localhost ~]# sudo apt-get install environment-modules

注意：安装完成后，已打开的终端要重新打开，命令才能生效。

语法格式

module [options] [command] [args ...]

参考实例

1. 列出已加载的模块：list

   [root@localhost ~]# module list
   No Modulefiles Currently Loaded.

2. 查看可用模块：avail

   [root@localhost ~]# module avail
   -------------------------------------------------- /usr/share/Modules/modulefiles ---------------------------------------------------
   dot  module-git  module-info  modules  null  use.own

3. 显示模块信息：show/display

   [root@localhost ~]# module avail
   -------------------------------------------------- /usr/share/Modules/modulefiles ---------------------------------------------------
   dot  module-git  module-info  modules  null  use.own
   
   ------------------------------------------------------- /root/privatemodules --------------------------------------------------------
   null
   [root@localhost ~]# 
   [root@localhost ~]# module show null
   -------------------------------------------------------------------
   /usr/share/Modules/modulefiles/null:
   
   module-whatis   {does absolutely nothing}
   -------------------------------------------------------------------
   [root@localhost ~]# 
   [root@localhost ~]# module display module-git
   -------------------------------------------------------------------
   /usr/share/Modules/modulefiles/module-git:
   
   module-whatis   {get last version of the module sources from GitHub}
   set-alias       get-modules {git clone git://github.com/cea-hpc/modules.git && cd modules}
   -------------------------------------------------------------------

4. 加载模块：add/load

   [root@localhost ~]# module load use.own
