Thanks for the panel suggestion.
As to not finding php, I've been using shell access here since 2004 - ksh, through a putty terminal. Never had a problem before. There is currently no .profile in my home directory, and I can assure you that I didn't delete it.
My .bash_profile was essentially empty:
~/.bash_profile: executed by bash(1) for login shells.
I don't even know where my PATH was being set.
Nevertheless, it is now set to:
but I'm still getting errors:
[yoda]$ which php
[yoda]$ whereis php
php: /etc/php /usr/local/lib/php
[yoda]$ php -v
-bash: php: command not found
Also, there is no php in /usr/local/bin on yoda
