初期化

ただ、インストールされEnvironment Modulesていないmodule、このシェルコマンド
の簡単な設定が必要ですsourceシーンのを

• ではprofile.d、ソフトの下で接続を確立するには、次の文を実行

# root用户
$ cd /etc/profile.d
$ ln -s /usr/local/Modules/init/profile.sh
$ ln -s /usr/local/Modules/init/profile.csh

# 普通用户
$ source ~/.bashrc

$ which module
module is a function
module () 
{ 
    _module_raw "$@" 2>&1
}
