I've never heard of that "leading space prevents it from ending up in your history" -- it doesn't work on my shell (bash 4.1.5).Ah! set HISTCONTROL=ignorespace (I've had ignoreboth, which ignores space-prefixed and duplicates for so long that I thought it was a default). If you're trying to hide the fact that you've run kvm, you'll also have to make sure none of it gets swapped,Again, I was making assumptions from my own configuration. But it's a hard thing... (In my case "swap /dev/sda3 /dev/urandom swap,cipher=aes-lrw-plain,size=256" in my crypttab makes my swap completely ephemeral, I run noatime on my systems, don't use a session managing desktop environment). It was foolish of me to make it sound so simple it's not but nor is it insurmountable.
