如何从命令行运行不带“节点”字样的Node.js程序

Question

I am developing the Node.js package, which includes a command-line utility. Now alacon.js is located in the root of the package. To run this utility I have to use word node before the name of utility, like:

 node alacon 'SELECT * FROM CSV("mydata.csv") ORDER BY 2'

Could you help me, what should I change in the package to:

1.To run this utility without node word, like:

 alacon 'SELECT * FROM CSV("mydata.csv") ORDER BY 2'

2.To install this package globally and use the utility everywhere on computer:

 npm install -g alasql
 alacon 'SELECT 2*2'

In other words, how to create utility like Jison, Gulp and other Node.js similar packages with command-line programs.

I already add the #!/usr/bin/env node line to the top of the file, but unfortunately have no desired effect.

Thank you!

Answer 1

You will need to make the script executable chmod a+x alacon .

Then you should be able to run ./alacon 'SELECT * FROM CSV("mydata.csv") ORDER BY 2'

If you wish to invoke the script without ./ then you will need to move it (or symlink it) to /usr/bin.

Alternatively - you could create an alias: alias alacon="node alacon"
