重建Mac OS X的打开方式列表

　　命令是使用这个：
　　/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/
　　Versions/A/Support/lsregister
　　
　　该命令帮助：
　　lsregister: [OPTIONS] [ <path>... ]
　　[ -apps <domain>[,domain]... ]
　　[ -libs <domain>[,domain]... ]
　　[ -all  <domain>[,domain]... ]
　　
　　Paths are searched for applications to register with the Launch Service database.
　　Valid domains are "system", "local", "network" and "user". Domains can also
　　be specified using only the first letter.
　　
　　-kill     Reset the Launch Services database before doing anything else
　　-seed     If database isn't seeded, scan default locations for applications and libraries to register
　　-lint     Print information about plist errors while registering bundles
　　-convert  Register apps found in older LS database files
　　-lazy n   Sleep for n seconds before registering/scanning
　　-r        Recursive directory scan, do not recurse into packages or invisible directories
　　-R        Recursive directory scan, descending into packages and invisible directories
　　-f        force-update registration even if mod date is unchanged
　　-u        unregister instead of register
　　-v        Display progress information
　　-dump     Display full database contents after registration
　　-h        Display this help


我使用-kill -seed -lint -r -f -v参数重建成功。
