I have solaris 10 installed on my computer and when try to login in console mode, it would give output something like this.
login:root

-sh: syntax error: `(' unexpected
-sh: grep: not found
-sh: uname: not found
-sh: test: argument expected
# ls
ls: not found
# clear
clear: not found
#
As you can see none of the commands work in this mode.
