You're executing a program so there is nothing to be overwritten. To kill all running redir processes type:
"console>" designates the linux console, commands here should be typed exactly, including all punctuation.
console>kill ps -aux --cols=900|grep redir|awk '{print $2}'
This should kill the process, then you can type the line over and correct your spelling mistakes. If you're locked in the process you can hit CTRL-C to terminate.
Hope this helped,
