I have installed ZSH in it by selecting Shells > Zsh in Select screen.

wget --no-check-certificate https://raw.github.com/haithembelhaj/oh-my-cygwin/master/oh-my-cygwin.sh -O -

Saving to: `STDOUT' - I don't think that's right, it should be saving to file STDOUT would be the terminal, I think? –  Sathya Nov 6 '13 at 17:27
I had this same problem, so I submitted a pull request to the repo owner. Now it's easier to copy and paste the installation command. –  Rodrigo López Dato Jan 16 at 12:43

Because of a missing line break on the source page, you missed the most important part of the install command: sh. The complete command should read

wget --no-check-certificate https://raw.github.com/haithembelhaj/oh-my-cygwin/master/oh-my-cygwin.sh -O - | sh

And given that, writing to stdout make perfectly sense.

However, better be always careful and don't blindly pipe an unknown script to sh. Instead you can download the commands to a file install.sh

wget --no-check-certificate https://raw.github.com/haithembelhaj/oh-my-cygwin/master/oh-my-cygwin.sh -O install.sh

Then, check what it's doing (less install.sh) and only then execute it

sh install.sh

O.O both of us answered "just now" (on my screen) with almost identical answers... dang –  allquixotic Nov 6 '13 at 18:54
@allquixotic: Yes, nearly to the second... hehe. –  mpy Nov 6 '13 at 18:55
@mpy thx for answer but even after running the correct command there is still problems screenpresso.com/=W1uae –  metal gear solid Nov 6 '13 at 19:39
@metalgearsolid I would suggest you execute the commands of the installation procedure (as listed in the outout in your question) manually. This way you can see which is the first problem. –  mpy Nov 6 '13 at 21:55
@mpy I got problem only at last which is showing in screenshot –  metal gear solid Nov 7 '13 at 4:45

If you look more closely at the github repo you just visited -- you will notice that the command line in the README.md below the repository is cut off (truncated) due to the formatting of the HTML of the page.

If you go here you will see that the full command is:

wget --no-check-certificate https://raw.github.com/haithembelhaj/oh-my-cygwin/master/oh-my-cygwin.sh -O - | sh

...which should work.
