Probably the simplest way to achieve this is with git archive. If you really need just the expanded tree you can do something like this.
git archive master | tar -x -C /somewhere/else
Most of the time that I need to 'export' something from git, I want a compressed archive in any case so I do something like this.
git archive master | bzip2 >source-tree.tar.bz2
ZIP archive:
git archive --format zip --output /full/path/to/zipfile.zip master
git help archive for more details, it's quite flexible.
Be aware that even though the archive will not contain the .git directory, it will, however, contain other hidden git-specific files like .gitignore, .gitattributes, etc. If you don't want them in the archive, make sure you use the export-ignore attribute in a .gitattributes file and commit this before doing your archive.

Note: If you are interested in exporting the index, the command is
git checkout-index -a -f --prefix=/destination/path/
(See Greg's answer for more details)
That would have to be:
db.users.find({"name": /.*m.*/})
Or, similar:
db.users.find({"name": /m/})
You're looking for something that contains "m" somewhere (SQL's '%' operator is equivalent to regular expressions' '.*'), not something that has "m" anchored to the beginning of the string.
Note: MongoDB uses regular expressions which are more powerful than "LIKE" in SQL. With regular expressions you can create any pattern that you imagine.
For more information on regular expressions, refer to Regular expressions (MDN).

For lazy people, use
mongodump, it's faster:And to "restore/import" it (from directory_backup/dump/):
This way, you don't need to deal with all collections individually. Just specify the database.
Note that I would recommend against using
mongodump/mongorestorefor big data storages. It is very slow and once you get past 10/20GB of data it can take hours to restore.
