Programatically write in a file in the environnent with a hush command

[Jean-Christophe BEGUE]

I didn't noticed -a and -o options for echo. That suits my needs, but
"nv" is exactly what I'm trying to acheive.

I'll use the kernel command line as well on early phases of my software boot.

Thank you!
