Use find to get around Argument list too long problem
Can be used for other commands as well, replace rm with ls. It is easy to make this shorter but if the filenames involved have spaces, you will need to do use find's "-print0" option in conjunction with xargs's "-0" option. Otherwise the shell that xargs uses to execute the "rm" command line will treat the space as a token separator, thereby treating the name as two (or more) names.

List your largest installed packages (on Debian/Ubuntu)
dpigs is in the package debian-goodies (debian/ubuntu)

Connect to all running screen instances
There was another line that was dependent on having un-named screen sessions. This just wouldn't do. This one works no matter what the name is. A possible improvement would be removing the perl dependence, but that doesn't effect me.

ettercap..
There weren't any one liners for ettercap on this site... tisk tisk :-) (of course you'll have to plugin your own values for the variables..)

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Find files with lines that do not match a pattern
This one would be much faster, as it's only one executed command.

Set pcap & SUID Bit for priv. network programs (like nmap)

yum -q list updates | tail -n+2

Display or use a random file from current directory via a small bash one-liner
An other way to run it ( playing a random file ending with avi, flv or mpeg ) from a specified dir and a specified type of extension : making MOVIE array with a glob : $ MOVIE=( /PATH/TO/MY/FAVORITE/MOVIES/*.{avi,flv,mpeg} ) playing the random file from a random key from the array $ mplayer ${MOVIE[ RANDOM % ( ${#i[@]} + 1 ) ]]} I use only globs and a bash array. I use GNU bash, version 3.2.48

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested
