Make a rake task fail if system call return error

I have a Rakefile that I use to automate some tasks in my project.

Inside some tasks, I call system, but, even if the process return an error, task continues without any issue.

How can I avoid that? I want to make rake exit when some subprocess return an error.

Thanks in advance

sh is the Rake way to call a command. It will fail with a neat message. Compared with system, sh prints out the command as well.

You can evaluate the return value of system

system('inexistent command') or exit!(1)
puts "This line is not reached"
