Process hdiutil output with PlistBuddy

Question

I'm trying to parse the output from hdiutil using PlistBuddy on the Mac terminal (without using a temporary file) and I'm running into some issues. I've tried the following:

Command 1

hdiutil info -plist | PlistBuddy -c "Print"

Output:

Prints the help for PlistBuddy

---

Command 2

PlistBuddy -c "Print" $(hdiutil info -plist)

Output:

File Doesn't Exist, Will Create: <?xml Invalid Arguments

---

I'm not great at bash but I think it might be an issue with PlistBuddy not accepting STDIN but only .plist files as input. Is there something that I'm missing or do I have to create a temporary file?

Answer 1

var=$(hdiutil info -plist)

PlistBuddy -c "Print" /dev/stdin <<< "$var"
