This is a bash script which will take an existing database archive (either a straight .sql file or compressed as .tar.gz, .gz, .tar.bz2 or .bz2) and import the database dump you define and then apply various config values once imported for things like base url.

The script accepts a number of arguments as follows:

a, absolute or relative path to the database archive to be imported.
m, absolute or relative path to the root directory of the Magento install the database is to be restored to.
n, optional argument containing the n98-magerun executable name (as it can be changed to anything from the default of n98-magerun.phar). If omitted the default of n98-magerun.phar will be used.
e, pass a comma separated list of paths to config variables that should be kept from database being replaced.

Logging has 3 arguments, the log file if used can be found at var/log/syncmagento.log inside the install the database is being restored to. If no argument is given output is shown in the terminal window only.

l, (lowercase L) output is sent only to the logfile nothing is printed in the terminal window
q, no output to either the terminal window or the logfile
b, output to both the terminal window and the logfile 

If the logfile cannot be output to (i.e permissions etc) then the script falls back to the default of outputting to the terminal and all logging arguments are ignored.

An example command to run the script might be:

./syncmagento.sh -bm /absolute/path/to/magento/root -a relative/path/to/database/archive/archive.sql.tar.bz2 -e google/analytics/account,paypal/general/business_account

File names for the database archive should contain .sql, so either just somefile.sql, or one of somefile.sql.gz, somefile.sql.tar.gz, somefile.sql.bz2, somefile.sql.tar.bz2. The contents of the sql dump is also checked to make sure the first line contains MySQL dump and the last line contains Dump completed and so appears to be a valid dump - a check is also first run to make sure the archive is actually readable.

The script must be executable for the user running it, also n98-magerun must be installed.

Before importing the new database dump the script will pull all of the secure and unsecure base url values which have been set at all store scopes (including for other paths like js and media), the same for the cookie domain (which can kill the ability to read session cookies and essentially kill the store if wrong), the same for secure front/backend settings and custom admin url configuration. Once the import is complete these config values are set against this new database.

Also as the databases can be pretty big it's worth using n98-magerun to actually create the database backup for use by this script so you can strip out unneeded data like log and session information to reduce the size of the dump.
