还有什么比使用更方便吗？RC默认应用或者魔法发射，还是只是反复按下 Finder 信息面板中的“更改全部”按钮？
我考虑编写一个 shell 脚本来修改 Info.plist 文件中的 CFBundleDocumentTypes 数组。但每个应用程序都有多个需要更改的键（有时是一个图标）。
lsregister不能用于对启动服务数据库进行特定修改。
$ `locate lsregister` -h
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

杜蒂
- 下载 pkg 安装程序或者从源代码编译
将这样的文件保存在某处：
com.macromates.textmate public.shell-script all com.macromates.textmate public.unix-executable all com.macromates.textmate com.apple.property-list all org.videolan.vlc .avi all org.videolan.vlc .mkv all # ...duti $file.duti
查找捆绑包标识符或 UTI：
bundleid() {
osascript -e "id of app \"$*\""
}
getuti() {
local f="/tmp/me.lri.getuti.${1##*.}"
touch "$f"
mdimport "$f"
mdls -name kMDItemContentTypeTree "$f"
rm "$f"
}
lsapps
在发现它之前，我编写了一个与 duti 非常相似的 Ruby 脚本。不过，它需要重新启动操作系统才能应用更改。它还会覆盖对 的任何外部更改com.apple.LaunchServices.plist。
#!/usr/bin/env ruby
datafile = "#{ENV['HOME']}/Notes/lsapps.txt"
cachedir = "#{ENV['HOME']}/Library/Caches/me.lri.scripts"
cachefile = cachedir + "/lsapps"
`mkdir -p #{cachedir}; touch #{cachefile}`
cachetext = IO.read(cachefile)
a = []
IO.readlines(datafile).each do |line|
line.strip!
next unless line =~ /^([^#].*): (.+)/
z = $1, $2
bid = cachetext.scan(/#{z[0]} (.*)/)[0]
unless bid
bid = `osascript -e 'id of app "#{z[0]}"'`.chomp
next unless bid
File.open(cachefile, "a") { |f| f.puts(z[0] + " " + bid) }
end
z[1].strip.split(" ").each do |e|
if e =~ /(.+):\/\/$/
a << "{LSHandlerURLScheme='#{$1}';LSHandlerRoleAll='#{bid}';}"
elsif e.include?(".")
a << "{LSHandlerContentType='#{e}';LSHandlerRoleAll='#{bid}';}"
else
a << "{LSHandlerContentTag='#{e}';LSHandlerContentTagClass=\
'public.filename-extension';LSHandlerRoleAll='#{bid}';}"
end
end
end
system("defaults", "write", "com.apple.LaunchServices", "LSHandlers",
"(" + a.join(",") + ")")
`defaults write com.apple.LaunchServices LSQuarantine -bool false`

您可以非常轻松地更改打开所有 AVI 的应用程序，无需编写脚本。找到一个 AVI 文件，然后对其执行“获取信息”。这将显示文件信息。选择要打开文件的程序，然后单击“更改全部...”按钮。这将提示您更改默认关联。
一个小问题，资源分支不会被淘汰，但创建者代码会被淘汰。因此，较新的 Mac OS 系统拥有更灵活的系统来确定如何打开文件。应用程序应该可以处理没有资源分支的文件，但有些应用程序仍在使用它们。
