How do I change directories?

Hi,
How do I change directory from a Ruby program?

I tried ‘system(“cd #{dir}”)’ but it didn’t work.
There must be a way.

Thanks all,

Ruby has its own chdir; you don’t have to ask the system to cd.

puts Dir.getwd
Dir.chdir(dir)
puts Dir.getwd

I hope this helps,

And if you do, you spawn a shell which will chdir and exits
afterwards, leaving nothing done…

puts Dir.getwd
system(“cd #{dir}; pwd”)
puts Dir.getwd
