d96d97ad30doc: Add release note for shutdownnotify. (klementtan)0bd73e2c45util: Add -shutdownnotify option. (klementtan) Pull request description: **Description**: Similar to `-startupnotify`, this PR adds a new option to allow users to specify a command to be executed when Bitcoin Core shuts down. **Note**: The `shutdownnotify` commands will not be executed if bitcoind shut down due to *unexpected* reasons (ie `killall -9 bitcoind`). ### Testing: **Normal shutdown commands** ``` # start bitcoind with shutdownnotify optioin ./src/bitcoind -signet -shutdownnotify="touch foo.txt" # shutdown bitcoind ./src/bitcoin-cli -signet stop # check that foo.txt has been created ``` **Final RPC call** Commands: ``` $ ./src/bitcoind -signet -nolisten -noconnect -shutdownnotify="./src/bitcoin-cli -signet getblockchaininfo > tmp.txt" $ ./src/bitcoin-cli stop $ cat tmp.txt ``` <details> <summary>Screen Shot</summary>  </details> ACKs for top commit: achow101: ACKd96d97ad301440000bytes: ACKd96d97ad30theStack: re-ACKd96d97ad30Tree-SHA512: 16f7406fd232e8b97aea5e58854c84755b0c35c88cb3ef9ee123b29a1475a376122b1e100da860cc336d4d657e6046a70e915fdb9b70c9fd097c6eef1b028161
Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt(GUI) orbin/bitcoind(headless)
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
