Pimp the command line
In this section, we are going to do instructions for changing the prompt "$" symbol to the Bitcoin symbol "₿" and color and install bash completion scripts for Bitcoin Core and Lightning projects command CLI instructions.
Difficulty: Easy
You can prettify your command prompt for each user by enabling color output and setting a custom prompt
- With user
admin, open and edit.bashrcas shown below. Save and exit
$ nano /home/admin/.bashrc --linenumbers
- Uncomment line 46
force_color_prompt=yes
- Comment the existing line 60 (backup)
#PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
- Add the next line (in line 61)
PS1="${debian_chroot:+($debian_chroot)}\[\e[33m\]\u@\h\[\033[01;34m\]\w\[\e[33m\] ₿\[\e[m\] "
- Insert the following at the end of the file
alias ls='ls -la --color=always'
- Apply changes
$ source /home/admin/.bashrc
- As user
admin, install bash completion scripts for Bitcoin Core and LND. You then can complete partial commands by pressing the Tab key (e.g. bitcoin-cli getblockch [Tab] → bitcoin-cli getblockchaininfo)
$ cd /tmp/
$ wget https://raw.githubusercontent.com/bitcoin/bitcoin/master/contrib/completions/bash/bitcoind.bash
$ wget https://raw.githubusercontent.com/bitcoin/bitcoin/master/contrib/completions/bash/bitcoin-cli.bash
$ wget https://raw.githubusercontent.com/lightningnetwork/lnd/master/contrib/lncli.bash-completion
$ sudo mv bitcoind.bash bitcoin-cli.bash lncli.bash-completion /etc/bash_completion.d/
Bash completion will be enabled after your next login
