The lsregister command is used to query and manage the Launch Services database, or the database that is used to determine the default application used to open files of various types. lsregister is part of Core Services, and stored in /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support. To see the options available to lsregister, run the command with no operators:/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregisterYou can dump the database to the screen using the -dump option:Library/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -dumpYou can then grep the database or redirect the output into a text file for parsing:The library overseer mac os x/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -dump > dump.txtSometimes applications don’t open with a given file type. When this happens, you can quickly and easily check if the problem has to do with the launchservices database. To do so run the open command and define the application (using the -a option) followed by the app and then the file. For example, to open an XML file called daneel.xml in TextWrangler (assuming your working directory contains bob.xml):open -a TextWrangler.app bob.xmlYou can force an application to re-register file types for that application using the -f option followed by the application path. For example, to re-register Xcode:/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -f /Developer/Applications/Xcode.appYou can also unregister a specific application using the -u option. To unregister Xcode you would use the -u option:/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -u /Developer/Applications/Xcode.appThe lsregister command is actually just a front-end management tool for the ~/Library/Preferences/com.apple.LaunchServices.plist file. The file’s contents can be read (in an unparsed form) using defaults:defaults read ~/Library/Preferences/com.apple.LaunchServices
The launchservices database is also responsible for determining whether a file type is quarantined by default (and those files that are quarantined throw a message to users when opened for the first time). To disable such a feature:defaults write com.apple.LaunchServices LSQuarantine -bool NOThe database can become pretty large and unwieldy. There are applications registered in the local domain, system domain and each user’s domain. You can always clear these out using the following command, which also recursively rebuilds based on the output of a -lint option:

To check the progress:/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -v

To set a specific application to open a file type, use the application’s domain out of the -dump output in an LSHandlerRoleAll and the file extension in an LSHandlerContentType in the LSHandlers array of com.apple.LaunchServices, as follows (to change txt for Text Edit – aka com.apple.textedit):defaults write com.apple.LaunchServices LSHandlers -array '{ LSHandlerContentType = 'txt'; LSHandlerRoleAll = 'com.apple.textedit'; }';You can also set the default application for a network protocol (e.g. smb://, rdp://, vnc://, http:// and https://). Because the options for lsregister leave one wanting in some ways (the commands to set file types to a specific application are a bit overly complicated one could argue), there is an awesome front end app from Andrew Mortensen, aptly called duti, available at http://duti.sourceforge.net/index.php. With duti installed, the command to set the default browser for http would be:
