Notes: * "contingency" is just a little shell script that resists being killed with SIGINT (SIGnal INTerrupt) and SIGABRT (SIGnal ABoRT) * Since I was running as 'AUX_ADMIN', I wasn't going to actually delete the account. * I was using ZSH * killall -ABRT contingency should really be 'rmmod contingency' or 'modprobe -r contingency' Code for 'contingency': #!/usr/local/bin/zsh trap "echo PERMISSION DENIED" SIGINT SIGABRT trap "echo OPERATION SUSPENDED" SIGHUP trap "echo TERMINATING PROCESSES..." SIGTERM while : do done Code for 'delete': echo "USER DELETED" # rather anticlimactic, isn't it?

'AUX_ADMIN's ~/.zshrc export PS1=" [!] " export PATH=$PATH:$HOME/.bin For the curious ones, here's a breakdown of what is done. 1.'contingency &' launches the program 'contingency', but runs it in the background. Without the ampersand (&), it wouldn't process any input. 2.'whoami' prints out the current user 3.'ps -U AUX_ADMIN' prints all the processes (ps) of the user AUX_ADMIN (-U AUX_ADMIN) 4.'killall -INT contingency' tries to send the Interrupt signal to all programs named contingency 5.'killall -ABRT contingency' tries to send the Abort signal to all the programs named contingency 6.'delete -u AUX_ADMIN' doesn't really do anything. In fact, there is not normally a 'delete' program in Linux. 7.'killall -STOP contingency' stops contingency in its tracks. 8.'killall -KILL contingency' forces contingency to quit.
