The Feds are here! (or, aliasing for those tight spots)
Aliasing commands is one of the most useful tools for automating important, difficult-to-remember tasks.
Here’s one I keep around for the right moment for my Mac:
alias feds-are-here='diskutil list | grep /dev | sort -r | \
xargs diskutil secureErase 1'
Or if I’m at my Linux box:
alias feds-are-here="fdisk -l | grep 'Disk /' | sort -r | \
awk '{print substr($2, 0, length($2))}' | \
xargs -I % dd if=/dev/urandom of=% bs=1M"
That way when I’m in a tight spot, I don’t have to remember which order to securely erase my drives. This command takes care of it for me.
Just a word of caution: it doesn’t ask first before starting the destruction.
