Terminal Command - TextEdit.app does not exist....

For a start, TextEdit.app isn't in /Applications, so your path is incorrect. It's actually in /System/Applications since it's part of the standard MacOS application set.

To overcome this, open has a standard method to find applications using the -a switch:

open -a TextEdit /path/to/some/file

This will use the standard system routine for finding an application and open the specified document in that app. You should only use the application path if you want to override the system. If you're trying to edit a text document, you can use:

open -e /path/to/some/file

which uses the system default text editor, again without needing to know its path.

HOWEVER, even with all that, if you're trying to edit that file you're doomed to failure since, by default, TextEdit won't edit system-related files (lack of permissions). You'll be OK if you're just looking at the file, but any changes won't be written back to that source. Even though you're using sudo to open the file, it won't save that file.

does /System/Applications/TextEdit.app work?

it looks like what finder shows you as "/Applications" is actually a combination of "/Applications" and "/System/Applications"

Installing the BBedit command line tools makes it even more useful!

It's in /System/Applications/; the Finder displays it in the main Applications folder as a convenience.

From the Terminal:

# display the open(1) man page in Preview
mandoc -T pdf -mdoc $(which -w open) | open -f -a Preview
# open a default empty TextEdit window
open -e
# open a plain text document in TextEdit
open -e foo.txt
# open a styled Rich Text document in TextEdit
open -e sample.rtf

Make sure that "Allow websites to ask for permission to send notifications" is not checked anymore.

Are you using anything called "CloudReach"?

Automated translation says that "Enhetsregistrering Cloudreach Inc. kan ställa in din Mac automatiskt." is Swedish for "Device Registration Cloudreach Inc. can set up your Mac automatically."

If the message was Swedish for "Your iCloud has been hacked!!!" or "You have 5 Trojan viruses!!! Remove viruses now!!!", it would clearly be a scam, sent by criminals. This message may be a scam, too – but seems worded a bit differently than the usual ones.

What are you actually trying to do? Regardless of whether you are ever able to get TextEdit to work, what you seem to be trying is most definitely not going to work.

Get BBedit. It open .plist files just fine, even if they are binary .plist files.
