Ruby on Rails

Hi McHenry & Diego

according to (http://www.linfo.org/cd.html) cd on its own does alternate between two directories like

~ $ cd /tmp

/tmp $ cd

~ $ cd

/tmp $

and so on ….

However! I've tested it on Mac and Fedora 20 — and the shell (Bash on Fedora) returns the user to the $HOME in both environments (hmmm)

Good spot, Diego!

Cheers,

Walther

Hi Diego. The command "cd ~" returns the user to their home directory however "cd" alone does nothing as far as I know.

In case you asked about the meaning of the command being used there, instead of what it does, it might be, correct me if I'm wrong, just to make sure you're in your home directory, just to make it is easier to follow.

Hi McHenry,

from your question I gather that you should perhaps start by going through one/two articles on the basic Linux commands - just to keep you a-float ;)

ls list directory

cd change directory

sudo execute som command as another user (superuser unless otherwise specified)

pushd cd and remember where you were at

popd cd to the remembered directory prior to the pushed one

cheers

Walther

I am using the following guide:

https://gorails.com/setup/ubuntu/14.04

Under the heading "Using rbenv" the first line instruction is "cd"

What is the purpose of this command?
