Running Groovy script from the command line

Question

When I did which groovy, I got the below output:

/usr/local/bin/groovy 

So I went ahead and created a helloworld.groovy with the below content

#!/usr/local/bin/groovy println "hello world" 

After that I did chmod +x helloworld.groovy and attempted to run the file with ./hellworld.groovy and sadly, I got this error ./helloworld.groovy: line 2: print: command not found

I could get rid of the error by changing to

#!/usr/bin/env groovy println "hello world" 

Why would the first method cause the error?

Answer 1

You need to run the script like this:

groovy helloworld.groovy
