Mercurial version control not working properly

I have just install Mercurial on CentOS and followed the tutorial here

https://www.mercurial-scm.org/wiki/TutorialInit

I created hello.txt in folder called mercury i.e

/home/user/mercu开发者_如何学编程ry/hello.txt

Then i did

hg commit -m "adding initial version of hello.txt"

Accoring to Docs it should create a folder called my-hello but thats not created

What can be the problem

The last sentence or so of the tutorial is wrong. It should really say something like:

"Nothing obvious changes about the files now that they've been committed, but this version of our files is preserved in the repository. We can confirm this by typing hg log which will show the revision"
