By some reason when I load msys I got this message:
 
sh: whoami: command not found
[: nicolay: unary operator expected
[: =: unary operator expected
sh: dircolors: command not found
sh: complete: illegal option: -o
complete: usage: complete [-abcdefjkvu] [-pr] [-A action] [-G globpat] [-W wordlist] [-P prefix] [-S suffix] [-X filterpat] [-F function] [-C command] [name ...]
I've uninstalled and reinstalled and found no way to correct this in my own. A search in the archives gave me nothing too.
 
So, this should be a very strange problem.
