I received an email with a plain text attachment (named 'noname') via Gmail and downloaded it using Chrome from gmail.com. It's a recurring automated report. Everyday I get the file , download it, open it, read it, and enjoy my life. Some days like today I get the file, download it and TextEdit on OS X won't let me open it.
TextEdit reports "The document "noname.txt" could not be opened. You don't have permissions."
A Get Info in Finder shows permissions:
ram (Me) Read & Write
Staff Read only
Everyone Read only
From a terminal I can do whatever I want to it (read, write, rename...). An
ls -l shows:
-rw-r--r--@ 1 ram staff
ls -le shows the same (i.e, no ACLs shown).
