Not a bad guess, but I can't reproduce it that way: unicorn:~$ bash unicorn:~$ alias cat=' ' unicorn:~$ cat /dev/null bash: /dev/null: Permission denied unicorn:~$ alias cat='' unicorn:~$ cat /dev/null bash: /dev/null: Permission denied Then I tried with a non-breaking space, and that's closer, but.... unicorn:~$ alias cat=' ' unicorn:~$ cat /dev/null bash: : command not found The "space nbsp space" in that result is interesting, but I don't think that's what he's doing, even accounting for the possiblity that he typed one space where the terminal shows three.
