Changed the PATH, now I'm getting "command not found" for everything

Amazon Linux Server, connected with SSH:

I tried to change the PATH for the apache user by making some changes in /etc/environment (PATH=$PATH:/opt/openoffice4/program) and /etc/sysconfig/httpd (export PATH = ${PATH:$PATH:}/opt/openoffice4/program).

Then I rebooted.

Now, I can not do anything, even ls -l leads to -bash: ls: command not found

What can I do to regain control?

What can I do to regain control?

Run /bin/vi and revert the changes you made to /etc/environment and /etc/sysconfig/httpd .

You can set your PATH without an editor. Just type this in the shell:

export PATH=/usr/local/bin:/usr/bin:/bin:$HOME/bin
