My node installation is at:
/usr/local/bin/node
and I've added the shebang:
#!/usr/local/bin/node
to the top of the file and given my node app file the permissions 755, but when I try to run:
> ./my-app
I get the old:
-bash: ./my-app: No such file or directory
What am I doing wrong?

Node. js can run shell commands by using the standard child_process module. If we use the exec() function, our command will run and its output will be available to us in a callback. If we use the spawn() module, its output will be available via event listeners.
Type node followed by the name of the application, which is test-node. js in this case, and then press Enter . The result of running the application will be printed out to the command prompt.
Shebang or hashbang ( #! ) is the first line of the file which tells the OS which interpreter to use. It typically looks like this: #!/absolute/path/to/the/interpreter [optional params]
js/JavaScript code. To launch the REPL (Node shell), open command prompt (in Windows) or terminal (in Mac or UNIX/Linux) and type node as shown below. It will change the prompt to > in Windows and MAC. You can now test pretty much any Node.
The node shebang is:
#!/usr/bin/env node Not all systems place node in the same location, its possible that you have the location incorrectly. This will find them all.
