Re: logon

It appears either /etc/profile or whatever has resulted in an unusable or
unset PATH environment variable. You are unable to issue the commands
because they can't be found. My earlier post was an attempt to prove it.
What happens when you do /bin/ls? If this is tru you can use the export
builtin command to set it and then correct /etc/profile or whatever is
"stuffing up".
