[root@linuxhelp11 ~]# source ~/.bashrc

In order to check NVM version use the following command

[root@linuxhelp11 ~]# nvm --version
0.33.8

In order to Check Node versions available run the following command

[root@linuxhelp11 ~]# nvm ls-remote
        v0.1.14

Now using node v6.14.1 (npm v3.10.10)
Creating default alias: default ->  v6.14.1

To check installed versions of the node use the following command

[root@linuxhelp11 ~]# nvm list

Now using node v8.11.1 (npm v5.6.0)

Check installed versions of the node using the following command

[root@linuxhelp11 ~]# nvm list
        v6.14.1
->       v8.11.1
