Backquote command execution path problem

C:\projeto>irb
irb(main):001:0> `cd`
=> "C:\\projeto\n"

How i change the path that the command will be executed ?

What must happen:

C:\projeto>irb
irb(main):001:0> YOUR_MAGIC_COMMAND("C:\\projeto\\blablabla")
irb(main):002:0> `cd`
=> "C:\\projeto\\blablabla\n"

Dir.chdir('C:\\projeto\\blablabla')

irb(main):002:0> `cd`
=> "C:\\projeto\\blablabla\n"

Do you want to change the path of the Ruby script? Then no "cd" in any subprocess will help - that only changes the sub process's path. Also, you might be confusing "cd" with "pwd" for printing the path. You probably want this:

irb(main):001:0> Dir.pwd
=> "/home/robert"
irb(main):002:0> Dir.chdir "/tmp"
=> 0
irb(main):003:0> Dir.pwd
=> "/tmp"
irb(main):004:0> `pwd`
=> "/tmp\n"

Kind regards

YOUR_DIR="C:\\projeto\\blablabla\n"
`cd #{YOUR_DIR}`
=> "C:\\projeto\\blablabla\n"
YOUR_DIR="C:\\projeto"
`cd #{YOUR_DIR}`

=> "C:\\projeto\n"
