I'm working on simple script that setup project structure for me (directories/files). I have an issue with retrieving argument passed as command line argument:
#!/usr/bin/env ruby
project_name = ARGV.first
puts "Provide project name" ; abort if project_name.nil?
When I try to run it, I get:
$ ./creator test
Provide project name
May be I'm not aware of something. When I do without #!/usr/bin/env ruby it works perfect.
Your problem has nothing to do with wether you execute your script with $ ./creator test or $ ruby creator test. The problem is that you always just print a static string with puts "Provide project name". I think this is more what you are after:
#!/usr/bin/env ruby
project_name = ARGV.first
abort if project_name.nil?
puts "Provide #{project_name}"
Here the project_name variable is substituted into the string, by doing #{project_name}.
