Mac OSX Running Application in bash, alias not working

Question

I'm trying to invoke headless Chrome in a rake task. It works in terminal, but doesn't in the rake task.

I've installed Chrome on Mac OS X, and created an alias to the application: alias chrome="/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome"

The command chrome --version produces the output: Google Chrome 61.0.3163.100

which chrome produces no output, and that seems odd. chrome --headless --disabled-gpu opens and closes a chrome session, as expected.

I want to run headless chrome in a Rails environment, and conducting rake tests:

namespace :chrome do
  task test_versions: :environment do
    p `chrome --version`
  end
end

Then run the rake task: rake chrome:test_versions resulting in: /User/username/.rvm/gems/ruby-2.4.2/bin/rake: No such file or directory - chrome

EDIT: After a few comments, I'm not addressing the real problem. I want to use rake tasks to invoke chrome headless in Mac.

Answer 1

which chrome produces no output, and that seems odd.

which is an external command which know notihng about Bash's aliases. You can use Bash's type command:

# type chrome
