• To retrieve a repository : git clone [<username>@]<host>:</path/to/repository>,
• tags related commands:
  • to list the tags of a repository : git tag,
  • to get the content of a repository at a given tag:
    • retrieve the repository with clone as indicated above,
    • git checkout tags/tag, with tag the wanted tag,
• to update a repository : git update.

You may want to update a repository with a totally new set of files, that is:

• retrieve the repository without the files,
• put all the needed files in the copy of the repository,
• update the repository to match the copy.

This avoids problems with overwriting of existent files, which may be convenient when using a script.

This can be done with following procedure :

• git clone --bare ... (you should then only have a .git directory in the repository),
• set the bare entry in the .git/config file to false (can be automated with sed "s/bare = true/bare = false/g" -i .git/config with GNU tools),
• put the files,
• git add -A,
• commit as usual,
• push with --set-upstream origin master options.
