    Oh, in the 90s I worked at a big defense contractor, one of a shell script had a suid on it, so just by creating a symbolic link named “-x” pointing to the script, and executing it, you entered in a root shell ☺️

    How to run a shell script with root permisions without sudo? su to root. Or set up the correct permissions for the script and whatever it needs to touch, and add your user to any required groups, so that you don’t need to be root to run the script. Rolling your own solution is never a good idea for anything security-related.

    Do you know how many times I’ve made some little bit of shell code “setuid” by writing a shitty little C program that just calls system()?
