[FIXED] How to run a command automatically after each reboot

Issue

I currently have Ubuntu 16.04 installed on my virtual box. I installed Ruby and Rails by RVM. After that I tried

$ rails

The terminal said

The program `rails` is currently not installed. You can install it by typing:
 sudo apt install ruby-railties

I solve this problem by typing

$ source ~/.rvm/scripts/rvm

However, once I reboot the virtual machine, everything I did with source will lose and I need to re-enter

 $ source ~/.rvm/scripts/rvm

I also have some similar cases I need to do on every reboot. So is there any solution can make those command be run automatically each time?

Solution

If you're using bash, add the line to the end your .bashrc:

.bashrc

source ~/.rvm/scripts/rvm

If you're using zsh, add it to you .zshrc.
