check the current working directory

[maven apache]

Hi:
I am new in mercurial, I want to know if there is a command can show me the
version of the current working .

For example, I use the command:

 $RepoB>hg push RepoA

And now how can I know the current version of working copy of RepoA though I
know I can use the "hg update" to make it synchronized with RepoB.


Also,is the pull opposite to push? Does these command override the
repository?
