Dear Max,

not quite sure whether I understand correctly what you want to do, but you should be able
to perform everything you need inside a Ruby script, within which you can change the
directory using a Ruby command and then execute any shell commands via the system or
backtick commands, and then switch back/again the directory using Ruby.

previous_dir=Dir.pwd
puts "your first directory was #{previous_dir}"
puts "System command pwd says we're here:"
p shell_previous_dir=`pwd`
Dir.chdir("/usr/local")      # in Linux/Mac; use e.g., Dir.chdir("C:/") in Windows
changed_dir=Dir.pwd
puts "you're now in directory #{changed_dir}"
puts "System command pwd says we're here:"
p shell_changed_dir=`pwd`
Dir.chdir(previous_dir)
puts "you changed your directory again, back to #{Dir.pwd}"
puts "System command pwd says we're here:"
p shell_changed_again_dir=`pwd`


Best regards,

Axel
