Recursively change file type I have folders, containing files and folders.
Among these files, some have extension, some have no extension.

I noticed that a file without extension can have a type (probably stored in some kind of metadata)

Example of a TextEdit file without extension :



Example of a Document Sublime Text file without extension :



What I want is recursively exploring folders and changing the type of files without extension.

I am not talking about setting a default app for all files without extension.

I am talking about changing each file individually (metadata), to set there type to "Document Sublime Text"

I am looking for something like that :

find ./ -depth &lt;file has no extension&gt; -exec &lt;set file type = Document Sublime Text&gt;


Or an AppleScript !
I did it with xattr !
My final script is :

find FOLDER -type f ! -name "*.*" -print0 | xargs -0 xattr -wx com.apple.LaunchServices.OpenWith \
"`xattr -px com.apple.LaunchServices.OpenWith FILEWITHGOODTYPE`"


Replace FOLDER by your folder (containing files without extension) (drag and drop)

Replace FILEWITHGOODTYPE by a file which has the expected type (drag and drop)
