Download & Setup

The Harmony CLI tool is used to interact with the Harmony blockchain.

Throughout this guide, we will use the following syntax:

./hmy: This is the CLI program
./hmy.sh -- : This is the command to use the CLI with a shell wrapper (for macOS)
<argument>: This is a required argument
[argument]: This is an optional argument
/ : This is a line break, used to break up a line while writing a command

Download Harmony CLI tool

1. For Linux

Enter the following command into your shell of choice:

If you have permission issues, enter the commands with "sudo" at the beginning, i.e. "sudo curl -LO && mv hmycli hmy && chmod +x hmy"

2. For MacOS

hmy depends on some dynamic libraries, hence we recommend using the shell wrapper. Enter there commands into your terminal:

Now you can use hmy.sh as a wrapper over hmy and you should assume that all references to hmy in these documents refer to hmy.sh. For example, the command ./hmy becomes ./hmy.sh -- .

Note that since hmy is not statically linked, you cannot arbitrarily move hmy.sh to anywhere on your filesystem like you could with a single binary.

3. Compiling from source

If you are interested in compiling from source, then the process is more involved.

Steps:

Clone the at the same level as the main Harmony repo:

Have , all built and prepared. This may require you to see instructions in the repo's readme.

Then setup the build flags:

Call make in the go-sdk repo. This builds a binary named hmy:

Congratulations! You can now use the binary to run the CLI.
