Linux CLI - Staking Calculator Script

  1. Install two dependencies jq and bc:
sudo apt install jq bc -y
  1. Create a new directory to store the script:
mkdir ~/pulsar-scripts && cd ~/pulsar-scripts
  1. Create the script file:
nano pulsar_staking_calc.sh
  1. Paste the following into the new file, changing the PULSARDIR path variable if you installed the wallet elsewhere:
#!/bin/bash

# Paths, change if you chose different names/locations
PULSARDIR=~

# Make sure bc is installed for floating point math
if [ ! `which bc` ]; then
        echo "Please install the 'bc' command by running:"
        echo "sudo apt install bc"
        exit 1
fi

echo ""

# If no --days argument was provided, use the default 7-day average
if [[ $# -eq 0 ]] ; then
        echo "Using default 7-day average"
        DAYS=7
else
  # If an argument was provided, sanity check and parse
  POSITIONAL_ARGS=()

  while [[ $# -gt 0 ]]; do
    case $1 in
      --days)
        DAYS="$2"
        shift # past argument
        shift # past value
        ;;
      -*|--*)
        echo "Unknown option $1"
        exit 1
        ;;
      *)
        POSITIONAL_ARGS+=("$1") # save positional arg
        shift # past argument
        ;;
    esac
  done

echo "Your wallet has minted an average of $AVGBLOCKS blocks/day ($AVGPLSR PLSR/day) over the last $DAYS days."
echo "Normalized to $BLOCKSPERDAYPER10K blocks/day ($PLSRPERDAYPER10K PLSR/day) for every 10k PLSR (assuming no deposits other than staking rewards)."

  1. Hit Ctrl+O and Enter to save your changes, then Ctrl+X to close the file.
  2. Make the script executable:
chmod +x pulsar_staking_calc.sh
  1. Run the script with the --days argument to specify how many days to average, or run without arguments to use the default of 7 days:
./pulsar_staking_calc.sh --days 14
