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. ⚠️ This command will automatically overwrite the previous file you downloaded.

    {% code overflow="wrap" %}

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

    {% endcode %}

  • If you have a custom aliases list in a personal private or public GitHub repository

    $ cd /home/admin
    $ wget <personal URL RAW list aliases> -O .bash_aliases
  • 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 --linenumbers
  • 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
    > 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)

Uninstall

  • To remove these special aliases, with 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
