MacOS – Does macOS have something like Linux’s binfmt_misc feature

macos

Linux has binfmt_misc which allows arbitrary executable file formats to be recognized and passed to certain user space applications. Does macOS have a similar feature?

Best Answer

No, macOS does not come with a similar feature.

If you're interested in adding it yourself, you can could take a look at this project:

https://github.com/georghe-crihan/imgact_linux

It is a kernel extension that extends the kernel's exec_shell_imgact() function to recognize other file types (namely Linux ELF binaries) and pass them to a user space application to be executed. The source code is available, so it could potentially be tweaked and extended to provide functionality similar to binfmt_misc.

MacOS – Display dialog from command line (like xmessage does)

One option is to tell a background process like SystemUIServer to display the dialog:

osascript -e 'tell application "SystemUIServer"
display dialog "message"
end
activate application (path to frontmost application as text)'

You can also tell the frontmost application to display a dialog, but it's not shown immediately if the application is not responding. If MPlayer OS X is frontmost, text dialogs don't accept any keyboard input.

osascript -e 'tell application (path to frontmost application as text)
display dialog "message"
end'

MacOS – Isn’t it redundant to have Versions as well as Time Machine

No it is not the same:

Versions: It is for different versions of your documents. You change something in your document and you can revert to an earlier version. This is not possible with Time Machine in this granularity.

Time Machine: It is for backup. It handle the case that you need to recover from a hard disk crash in your mac. You can't do that with versions since versions saves your changes on the then defect hard disk.

So they have their purpose since they „solve“ different problems.
