I am on step 9 and I can't figure out how to do this correctly if someone could help me that would be great.

OK, first off: the reason not many people have replied to this thread is because the tutorial seems to be about Gems for Rails (which I guess is a ruby variant?). Either way, it's not really about php at all.
Moving on from that - what is the nature of your problem? What do you do and what happens? What editor are you using to add the 'GEM_PATH'?
Other things that occur to me would be the apparent typo 'envorinments.rb', I'm pretty sure thats supposed to be 'environments.rb'.

Im sorry Goheadtry but is it more or are you trying EVERYthing possible and seemly being lcue less with most of it?

i think you should focus more on one area -> master it -> move on to something else.

from yours posts your diving into 20 differant topics at once. :s

Okay I can't get past step 9 because I can't figure out which key to push in the ssh client name "PUTTY" so

$ vi ~/RailsApps/app1/config/environment.rb
ENV['GEM_PATH'] = '/home/yourusername/gems:/usr/lib/ruby/gems/1.8'

is the code I can't figure out how to make it save I am still in a mode where it is allowing me to type I just need to know which Key I need to push after I do this so it saves. Here is an image of it

when you enter the command vi you are opening or creating a file. So what this is telling you to do is to open the file environment.rb. Once this file is open, that's where you would edit the GEM_PATH.

I always like to make sure that the file exists because otherwise when you use the vi command, it'll automatically create the file. So when you expect to see a config file, it'll be empty if you have the wrong path to the real file.

So I would try this first.

Command to enter: cd ~/RailsApps/app1/config

Command to enter: ls

Do you see a file called environment.rb?

If you do:

command to enter: cp environment.rb environment_copy.rb

command to enter: vi environment.rb

vi starts in command mode, to start type you need to hit the lowercase i button.

I would also suggest reading up on how to use vi.

If the file don't exists, vi will create a new one when you save it.
If the file exists, then you'll see it's content when vi loads.
So nothing to fear here.

Basics commands for VI are:

! -> force the command 
  q! means quit even if I don't have saved the file
  w! means try to write the file even if i don't have the permission
i -> enter writing mode
esc -> go back from writing mode to command mode
number + G -> go to the line number x
G -> Go to the end of the file
o (the letter) -> Add a line after the cursor and enter edit mode
O (the letter) -> add a line before the cursor and enter edit mode
w -> write file
w! -> Force to write the file (if the content changed, or sometimes when permissions on the file are messed up)
q -> quit vi
wq -> write and exit vi
w!q -> try to force the file write even if the permissions are wrong, and exit
%s/aaa/bbb/gi -> replace every "aaa" with "bbb" through all the document
/ + aa-> Search "aa" from the current cursor position
dd -> delete the line under the cursor
d+ uparrow / down arrow -> delete the current line + next or previous one
u -> undo

You must hit "esc" to switch back from writing mode to command mode.
Remember that you need to be in command mode for those to work, and that command start with : .
So, to write the file when you are editing it, type the sequence

esc : w i

to exit to command mode, write the file, and enter back in edit mode.


2 things: Try to use vim, it's more advanced. You may already use it when you type vi, it's distribution dependant.
If vi is too much, try nano. It's often installed by default, and it's operation mode is more like you are used to, for sure.
Remember than in command mode, you cannot write, and in writing mode, you must go back to command mode to do an action.

vi ftw!

however, if you are just starting out w/ a linux editor, nano is a more noob friendly editor. try typing 'nano filename.txt' instead of 'vi filename.txt'. It may already be installed.

If not, try

yum nano

and then

nano environment.rb
