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 by Raspibolt community at Github. ⚠️ This command will automatically overwrite the previous file you downloaded.

    $ cd /home/admin
    $ wget https://raw.githubusercontent.com/raspibolt/raspibolt/master/resources/.bash_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:

    > lntop version v0.3.0
    > nginx version: nginx/1.18.0
    
    $ livehealth
    > Every 1.0s: vcgencmd measure_clock arm; vcgencmd measure_temp raspibolt: Tue Dec 14 15:00:21 2021
    > frequency(48)= 124121523
    > temp=37.0'C
    

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
