Aliases

Aliases are shortcuts for commands that can save time and make it easier to execute common and frequent commands. The following aliases do not display information in a fancy way, but they make it easier to execute commands.

{% hint style="success" %} Difficulty: Easy {% endhint %}

{% hint style="success" %} Status: Tested MiniBolt {% endhint %}

Acknowledgments

The following list of aliases was derived from contributions by RobClark56 and 2FakTor

Set up aliases

  • With user admin, access to home folder and download the aliases list provided for a MiniBolt environment

{% code overflow="wrap" %}

$ cd /home/admin

{% endcode %}

{% code overflow="wrap" %}

$ wget https://raw.githubusercontent.com/minibolt-guide/minibolt/main/resources/.bash_aliases -O .bash_aliases

{% endcode %}

If you want, inspect the list of aliases to make sure it does not do bad things, and modify it with your personal aliases if you want. Exit with Ctrl-X

$ nano .bash_aliases

  • Execute a source command to register changes of the .bash_aliases file in the .bashrc file

    $ source /home/admin/.bashrc

Aliases in action

  • Simply type "alias" to display all available aliases

    [...]
alias enableallmain='sudo systemctl enable bitcoind electrs btcrpcexplorer lnd rtl scb-backup'
alias enablebitcoind='sudo systemctl enable bitcoind'
alias enablebtcrpcexplorer='sudo systemctl enable btcrpcexplorer'
alias enablecircuitbreaker='sudo systemctl enable circuitbreaker'
alias enablecln='sudo systemctl enable cln'
alias enablefulcrum='sudo systemctl enable fulcrum'
[...]

  • Test some of the aliases to see if it has been installed properly

$ showmainversion
Example of expected output ⬇️ 
> The installed versions of the services are as follows:
> Bitcoin Core version v23.0.0
> lnd version 0.15.3-beta commit=v0.15.3-beta
> BTC RPC Explorer: "version": "3.3.0",
> Electrs: v0.9.9
> RTL: "version": "0.12.3",
> Tor version 0.4.7.10.
> NPM: v8.15.0
> NodeJS: v16.17.1
> htop 3.0.5
> nginx version: nginx/1.18.0 (Ubuntu)

For the future: upgrade Aliases

Follow again the Set up Aliases section again to overwrite aliases.

{% hint style="info" %} You can see if the aliases have a recent update by entering here {% endhint %}

Uninstall

  • To remove these special aliases, with the user "admin", simply delete the .bash_aliases and execute a source command to register changes. The aliases will be gone with the next login.

    $ rm ~/.bash_aliases

  • Execute a source command to register changes to the .bashrc file:

    $ source /home/admin/.bashrc
