I'm intrigued by your uname command. What kind of information adds to this case? Honest question, I would have expected the following command to provide context: $ which --version | head -1 GNU which v2.20, Copyright (C) 1999 - 2008 Carlo Wood. Or may be the output of lsb_release, although it may not be installed in your system. Is "which" behaviour dependant on the kernel version? EDIT: formatting; also to add that which writes to stderr if the command you're asking for can't be found in the path.
