Split the string to get only the first 5 characters

Question

I would like to go to the location /var/log/src/ap-kernelmodule-10.001-100

But looks like my code has to deal with ap-kernelmodule-10.002-100, ap-kernelmo

Answer 1

You can't be in multiple cwds simultaneously. To run the command for each directory that matches the pattern, you can use Dir#glob:

Dir.glob('/var/cache/acpchef/src/ap-kernelmodule-10*').each do |cwd|
  Mixlib::ShellOut.new("command run here", cwd: cwd).run_command
end
