I added these lines to my .bashrc file:

export vertx_home=/anto/vertx/bin

export PATH=${PATH}:${vertx_home}/bin

after doing that. I get an error message like that for all command's I run, for example:clear,groovy :

Command 'clear' is available in '/usr/bin/clear'

The command could not be located because '/usr/bin' is not included in the PATH environment variable.

clear: command not found

How to recover from it?

I'm new to Ubuntu. Kindly help.

Thanks in advance.
