In this thread you've been messing around with the PATH settings. I'm fairly certain you messed that up.When I press ls it gives me command not found.
/bin/ls
work? If yes, then your PATH is messed up.After you're done with that, inspect the output of "set". You should be able to explain why every line in there exists, and what it does.
Ah, no worries then. Are you still unable to run commands with or without the full path? and did you follow ralphbsz advice?Sorry not press. Typed ls.
