Attempting to follow these instructions and I'm receiving error zsh: command not found: ord when attempting to do anything in ord, including ord wallet create. Currently running ohmyzsh and have not altered the .zshrc file. When I use echo $PATH, I receive /Library/Frameworks/Python.framework/Versions/3.11/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin I'm new to this, so my apologies if the answer is obvious. Any help would be greatly appreciated.

What are the Dependencies of Electrum bitcoin wallet in different distros? 1. void 2. opensuse-tumbleweed 3. opensuse-leap 4. nethunter 5. fedora 6. centos 7. backbox 8. arch 9. alpine I know it's the same in these three distros: ubuntu kali debian

I noticed that I am unable to change the StateDirectory of a [blockchain](https://github.com/bitcoin/bitcoin/blob/999f8b24cca3ea3f2e19773adda4554b7e40de0c/contrib/init/bitcoind.service#L55) to an external hard drive because I believe that systemd only allows relative paths for the StateDirectory option. The reason I want to use an external hard drive is that my service's state is notoriously large. Specifically, I want to use it to store the bitcoin blockchain. Should I simply forget about using a StateDirectory, or is there some other option? Or, do I have an incorrect concept of how to use StateDirectory entirely?

I'd like to maintain a BTC node / wallet on a VM within VirtualBox. For this I installed Arch Linux, manually. The process wasn't the smoothest experience, but I got it working, eventually. Then I used this guide to install _yay_, successfully. I went ahead and tried to install _bitcoin-core_ by running yay -Sa bitcoin-core --answerclean y --answerdiff n. The installation takes long and fails, eventually. After a lot of lines starting with CXX I got these lines:

The relevant line seems to be unknown location(0): fatal error: in "arith_uint356_tests/basics": std::runtime_error: locale::facet::_S_create_c_locale name not valid. The only similar issue I found was from this question and the solution makes sense. However, the contents of my /etc/locale.conf are:

LANG=en_US.UTF-8

I also run locale-gen before and edited my /etc/locale.gen to only have en_US.UTF-8 UTF-8 active (not commented). How can I get past this issue?

I was wondering if there was code to find every string of a certain length in a text file and save each one as a new variable? For example, there are 5 strings in a text file. Two of them are 3 characters long. The idea is to parse out all the strings which are 8 characters long and put them in variables going in sequential order, e.g. var1, var2, var3. How would I make this? Thanks! (For those wondering, I found an old file on my PC with a bunch of bitcoin wallets with private keys, trying to save them all as variables to check their balances.)

Today's question of mine was **How do I install Electrum 2.6.4** Bitcoin wallet on my Linux Mint 18.

So I own a device (casa node) which is basically a raspberry pi 3b+ with a hard drive and a modified OS (they call it CasaOS) and I want to edit a file. I found the location of this file by looking at the debug logs of the program that uses it. here's what they look like: 2019-01-05T22:11:44Z Bitcoin Core version v0.17.0 (release build) 2019-01-05T22:11:44Z InitParameterInteraction: parameter interaction: -whitelistforcerelay=1 -> setting -whitelistrel$2019-01-05T22:11:44Z Assuming ancestors of block 0000000000000000002e63058c023a9a1de233554f28c7b21380b6c9003f36a8 hav$2019-01-05T22:11:44Z Setting nMinimumChainWork=0000000000000000000000000000000000000000028822fef1c230963535a90d 2019-01-05T22:11:44Z Using the 'standard' SHA256 implementation 2019-01-05T22:11:44Z Default data directory /root/.bitcoin 2019-01-05T22:11:44Z Using data directory /usr/local/casa/chains/bitcoind/data/ 2019-01-05T22:11:44Z Using config file /usr/local/casa/chains/bitcoind/conf/bitcoin.conf The bitcoin.conf is the on I'm after, however I can't get in the directory. Once I'm in /usr/local/casa I can't see or cd into the chains dir. the ls -a command returns . .. applications launch.sh How can I get in the chains folder and ultimately to the bitcoin.conf file? I did all of this as root.

### Description Hello, I'm trying to loop over certain commands and save their outputs into a file, and while looping through those commands, also check the file which we saved their outputs so we can compare them from the file while looping the commands at the same time. In the end, check if the looped commands' outputs match with the previously saved outputs in that file. *(Also check if the file doesn't contain the output and add it into the file so we can later use it to compare again)* This is my main script which loops through the said commands which are located inside /usr/local/bin/ so I can run them directly from the shell.

#!/bin/bash
wallets=find /usr/local/bin/ -iname '*-cli'

for i in $wallets; do
    current_blocks=$I getblockcount
    coin_name=${i:15:-4} # I use :15:-4 here to cut the path and the last 4 characters. (For example it's /usr/local/bin/bitcoin-cli so I change it to bitcoin only
    echo $coin_name $current_blocks
    echo $coin_name $current_blocks >> blocks.log
done

And this echo gives us exactly this (assuming there are 2 items in the $wallets;

bitcoin 1457824
litecoin 759345

And this is the while loop I will -presumably- be using to read from the file;

while read line ; do
    set $line
    echo $1 $2
done = "$2" )); then
				echo "Current blocks are greater than the saved blocks"
				echo "Saving the new blocks count now"
				sed -i "s/$1/$1 $current_blocks/" blocks.log
			else
				echo "Current blocks are less than or equals to saved blocks"
			fi
		else
			echo "File does not contain the coin_name, adding it now"
			echo "$coin_name $current_blocks" >> blocks.log
		fi
	done = "$2" )); then
            echo "Current blocks are greater than the saved blocks"
            echo "Saving the new blocks count now"
            # sed -i "s/$1/$1 $current_blocks/" blocks.log
        else
            echo "Current blocks are less than or equals to saved blocks"
        fi
    else
        echo "File does not contain the coin_name, adding it now"
        echo "$coin_name $current_blocks" >> blocks.log
    fi

done

What am I doing wrong?

I even included source /home/user/.bashrc; in crontab, still it does not output correct thing. I have a while loop in my script which checks some value from a service called zend. It is like bitcoind but for Zen. The function looks like this, I put it here check_existing_balance_withoutfl should be greater than 0 but it is saying that it is 0 when I run from cron. { declare -i bal; bal=0 while [ $bal -le 1 ] do # #code to send zen to z addresses echo "Balance is $check_t_balance"; logger "Balance is $check_t_balance"; sleep 5 # This following line is essential at this particular place export_address=$(zen-cli listaddresses | jq -r '.'); if python -c "import sys; sys.exit(0 if float($check_t_balance) = float($min_ask_zen) else 1)"; # if [ $(bc = $min_ask_zen") -eq 1 ]; then #statements echo "ZEN balance is sufficient" echo echo "We have received $check_t_balance zen in $export_address this t address" echo echo "Now, this will be sent to two z-addresses" && echo logger "Now, this will be sent to two z-addresses" && echo # # Recommended tx_fee is >= 0.0001 # # Increse here if needed # tx_fee=0.0001; amt_aft_txfee=$(python -c "print(float($check_t_balance-$tx_fee))"); amt=$(python -c "print(float($amt_aft_txfee/2))"); echo "Sending now.... $amt ZEN to two z addresses" topUpzksnark; # # zen-cli z_sendmany $new_imported_address '[{"address": "'$(zen-cli z_getnewaddress)'", "amount": $amt},{"address": "'$(zen-cli z_getnewaddress)'", "amount": $amt}]'; echo "$amt ZEN is sent to two Z addresses" else echo "ZEN balance is not suffiecient" moreZentoSend=$(python -c "print(float($min_ask_zen-$check_t_balance))") echo "Please send at least $moreZentoSend Zen to $export_address this address" >> /home/rock64/log.txt logger "Please send at least "$moreZentoSend" Zen to "$export_address" this address" echo "bal is $bal" >> /home/rock64/log.txt fi declare -i bal; declare -i check_existing_balance_withoutfl; echo "check_existing_balance_withoutfl is $check_existing_balance_withoutfl" >>/home/rock64/log.txt; check_existing_balance_withoutfl=$(zen-cli z_gettotalbalance | grep total | tr -d '," ' | cut -d ':' -f2 | tr -d '.' | bc); # check_existing_balance_withoutfl=$((10#$(zen-cli z_gettotalbalance | grep total | tr -d '," ' | cut -d ':' -f2 | tr -d '.'))); # check_existing_balance_withoutfl=$((10#$check_existing_balance_withoutfl)); bal+=$check_existing_balance_withoutfl; echo "check_existing_balance_withoutfl is $check_existing_balance_withoutfl" >>/home/rock64/log.txt; echo "bal is $bal after if else" >>/home/rock64/log.txt done } logs when sudo crontab -e used with 55 8 * * * source /home/rock64/.bashrc; /home/rock64/light.sh > /home/rock64/both.log 2>&1> check_existing_balance_withoutfl is 0 bal is 0 after if else There is not enough balance in the node T Address check_existing_balance_withoutfl is 0 check_existing_balance_withoutfl is 0 bal is 0 after if else If I run the script not from crontab, everything works normal as usual. $ check_existing_balance_withoutfl=$(zen-cli z_gettotalbalance | grep total | tr -d '," ' | cut -d ':' -f2 | tr -d '.' | bc) rock64@cheese:~$ echo $check_existing_balance_withoutfl 498 Why bal is not 498 then, when it was executed from cron? I have literally no idea, what is wrong I am doing. After looking at the bash -x log as suggested by @Marcel, it seems, I found the problem. Since, I put my script in

crontab -e

, it was referring to a config file in /home/root/.zen directory, so for the zend client I had to replace all zen-cli lines with zen-cli -conf=/home/user/.zen/zen.conf in my script. Same applies to bitcoind, if someone ever wants to put bitcoin-cli in crontab to check some specific transactions or whatever.

I would like to use my Linux console to read Bitcoin price from specific exchange using one-liner command. I were able to achieve that using Curl with the following command. curl -sSL https://api.binance.com/api/v1/ticker/price?symbol=BTCUSDT | head -n 1 | sed "s|^.*,|$|" | sed "s|\(\.[0-9]$\)|\10|" But I noticed a delay while retrieving the price and it's shown the price on the console wrongly.

I'm running Debian 7 stable and because the old version available on Wheezy can't send out BTC, I'd like to upgrade to a newer version which is available in jessie-backports. Is it possible to use that version? If so, how to modify sources.list?
