Unix & Linux: How do I kill all screens?

The Question: I accidentally created over 1000 screens. How do I kill them all with one
command? (Or a few)

You can use :
pkill screen
Or
killall screen
----
In OSX the process is called SCREEN in all caps. So, use:
pkill SCREEN
Or
killall SCREEN

I'm a bit puzzled over how you managed to create 1000 "screens". Did you
perhaps mean 1000 screen windows (1000 different terminal windows within a
single screen session)?
If you meant 1000 windows within a single screen session, then a more elegant
solution would be to quit screen using the command C-a (ctrl-a followed by ).

If the screens are dead, use:
screen -wipe

== This solution helped 6 people ==
str=$(screen -ls)

array=$(echo $str|tr "." "n")

for V in $array
do
if [ $V -gt 0 ]
then screen -S $V -X quit
fi
done

Have recently begun to familiarize myself with awk I put together this and it
served its purpose. I posted it since its quite easy to understand.
screen -ls | grep '(Detached)' | awk 'sys {screen -S $1 -X quit}'
Where screen -ls lists all current screens. grep 'pattern' filters out all
matching rows. We can then get a handle for all detached screens and with awk
sys {command} we can copy and paste together a command and execute it with sys,
$1 refers to the first argument picked up by awk. Finally we execute the quit
command with screen -X quit.

The following command will terminate all inactive screens:
perl -e 'while (map { kill 9, [split /./]-＞[0] } grep { /Detached/ } split /n/,
qx{screen -ls}) { sleep 1 } exec qw(screen -wipe)'
