When you clone a repository in Mercurial, it creates a file
.hg/hgrc in the new clone repository. Typically, this has the following lines:
[paths] default = https://firstname.lastname@example.org/joe/foobar
That is, it has the login, the source location (directory or internet domain), the repository owner and finally the repository name. This assigns a symbolic name of
default to this repository. After this any push or pull command is done with this repository.
If you created a new Mercurial repository and want to push it to another existing repository, then the command is:
$ hg push https://email@example.com/joe/foobar
If you want to push or pull without having to specify the repository, then just create a
.hg/hgrc file and add the above lines to it.
If you want to add other repositories to push-pull from, add them on separate lines with a different symbolic name, not
[paths] default = https://firstname.lastname@example.org/joe/foobar bkp = https://email@example.com/joe/foobar
You can push-pull from that repository using the symbolic name you have given it:
$ hg pull bkp
Tried with: Mercurial 2.0.2 and Ubuntu 12.04 LTS
