Kernel#`` not working in my IRB

[Love U Ruby]

I tried Kernel#`` but not working `cd` command.

kirti@kirti-Aspire-5733Z:~$ irb --simple-prompt
>> `pwd`
=> "/home/kirti\n"
>> var = `cd 'ruby'`
=> ""
>> var
=> ""
>> `pwd`
=> "/home/kirti\n"
>>

Because Kernel#` is a fork per command scenario not a session. `cd
'ruby' && pwd`

fork per command means? Could you please clarify this ? I am using it
first time.

It worked perfectly. It created a new process, that process changed its directory, and then exited ;-)

Maybe you want Dir.chdir?
