Kusama Kommand Mac OS

When first booting up a Kusama node, it may take a while for it go get in sync with the latest block. Depending on how long the chain has been alive, your hard drive speed, your bandwidth, and some other factors, it can take days.

On Mac OS X only I need a command line to get the mac address of the wifi currently in use. Macos shell mac-address. Follow edited May 9 '20 at 20:05. 103 1 1 silver badge 7 7 bronze badges. Asked Feb 23 '15 at 22:54. Terminal (Terminal.app) is the terminal emulator included in the macOS operating system by Apple. Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of macOS. As a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of macOS, by providing a command-line interface. ‎A high level of file management can be reached with the updated version of Commander One v3.0. The app is now fully compatible with macOS Big Sur, offers more efficiency, stability, and improved functionality. Commander One is a free file manager created in Swift, has a dual-pane interface that he. Bash is the default shell, it runs under Darwin the open source core of macOS. In macOS Catalina the default shell will change to zsh and in time this page will be updated to include that. Discussion forum See also: Websites, Books, Apps & Utilities for macOS.

To save time, you can import a database that's already fully synced. First, you need to be aware of the two types of database supported by any Substrate based chain, including Kusama.

  • RocksDB is the industry standard, and used in most blockchains. It's one of the fastest databases out there, is extremely lightweight, and has good compression. This is currently the default.
  • ParityDB is a new database, custom built for blockchain data. It performs better in this niche than any other database out there, but at the cost of storage - it takes up much more disk space.

Either is fine, though ParityDB is preferred as it's likely to become the default soon.

Importing the Database

We assume you have a working Kusama or Polkadot node on your machine. If you are on Linux-based systems or the WSL (Windows Subsystem for Linux), you can download a pre-built Kusama node (Linux binary) from the release page. While it is possible to compile and run a node on native Windows and Mac OS, it is not recommended for long-term stability, as those operating systems are not built for long continuous operation.

The node needs to be run in archive mode, so the option --pruning=archive needs to be appended unless you're running a validator in which case it's the default.

Kusama Kommand Mac Os X

Here's an example command to run the Kusama node provided you're in the folder which contains the binary:

As stated earlier, this will default to RocksDB. To use ParityDB, use:

The database folder will be created in ~/.local/share/polkadot/chains/ksmcc3 by default, with ksmcc3 replaced by polkadot if you're using the Polkadot chain. If you used RocksDB, there will be the folder db. If you used paritydb, there will be the folder paritydb.

You will need the 7zip program to unzip this. First, rename the downloaded file from Qm.... to archive.7z. Now simply uncompress the previously downloaded archive in place of the appropriate folder (make sure the node is not running before doing this). The output of the decompressing will be the folder (db or paritydb) so you can just uncompress into the ksmcc3 / polkadot folder directly. This is probably easiest to do through a user interface, but if you want a command:

Now relaunch your node with the desired db option, and it will continue syncing from where this archive left off.

This guide is about the Run AppleScript from the Command Line in Mac OS X with osascript. I will try my best so that you understand this guide very well. I hope you all like this guide Run AppleScript from the Command Line in Mac OS X with osascript.

Mac users can choose to run AppleScript from the command line either by running the script file directly or by giving direct text file annotations to the oscascript command. This can be useful for many purposes, but it should be especially nice for users who spend a lot of time on the command line or perform remote management tasks with ssh.

The osascript command executes any OSA script, we will focus on AppleScript here, but you can also use oscript to execute Javascript yourself if you use the flag to adjust the language.

Executing AppleScript script files from the command line

To run the AppleScript script file from a Mac OS terminal, point to the oscillos .scpt script file path as follows:

osacript /example/path/to/AppleScript.scpt

For example, if you automatically saved this script to connect to a VPN as a script file as an application, you can point the oscascript command directly to the file to execute it. Any .scpt file can be launched simply by pointing the partscript command to the correct path, whether it was created in the AppleScript script editor or a plain text file, no matter when the syntax needs to be correct.

Execute AppleScript script expressions directly from a terminal

If you want to run a specific AppleScript script or statement without saving it as a .scpt file, you can simply use the -e flag and then the necessary single and double quotation marks to quote and avoid the script.

A few examples:

osacript -e ‘dialog 'Hello from bollyinside.com' titled 'Hello' '

Displays a dialog box that says 'Hello'

osacript -e ‘tell 'Finder' to create a new Finder window '

Opens a new Finder window

osacript -e 'set the volume to 0'

Mutes the system volume.

We've dealt with a number of short AppleScript in the past using the partscript command, including smoothly closing Mac OS applications from the command line, setting Mac wallpapers from the command line, deleting all installed volumes, muting, or changing system volume. Anyone interested in learning more about AppleScript can find a significant amount of information, syntax, commands, and helpful guides in the ‘Script Editor' that comes with MacOS and Mac OS X.
