One way to run it is from the current directory with the "./edbg..." syntax. If you want to use it from whatever location on the system, which is the case when you have multiple projects that reside in different directories, you have to move the "edbg..." file to "/usr/local/bin" folder on Linux and Mac systems. To do that, in Terminal, make sure that you are in the directory where the "edbg..." file resides. Use the following command.
´´´
```
sudo mv edbg-linux-r61 /usr/local/bin/edbg
´´´
```
The above example is for Linux, but on Mac it should be the same, except the linux is going to be "mac". What will happen is that Terminal will ask for the admin password (which you will happily provide) and it will move and rename the file "edbg-linux-r61" to "/usr/local/bin" folder with the name "edbg".
To verify that you can use it, type ´edbg --help´ and hit enter. You should see something like the following.
