Kill all detached screen sessions

Question

When I execute screen -ls, I see the following. How can I kill all the detached sessions?

There are screens on:

    84918.tty         


        

Answer 1

Combining Edward Newell's and Rose Perrone's solutions into a more readable and "screen" like solution.

Add below to your .bashrc or .bash_profile.

# function for killing all detached screen sessions
killds() {
    detached_sessions=$(screen -ls | grep Detached | cut -d. -f1 | awk '{print $1}')
    for s in ${detached_sessions}
    do
        screen -S "${s}" -X quit;
    done
}
