    Piping curl into sh in install instructions is a fast track to me not taking a project seriously

      I’ve heard this over and over… what’s the difference security-wise between sudo running some install script and sudo installing a .deb (or whatever package format) ?

        A deb is just a zip file that gets unpacked to where your binaries go. A shell script you curl pipe into shell could contain literally any instructions

          Binary packages have scripts (IIRC for .deb they are preinst/postinst to be run before/after installation and prerm/postrm before/after removal) that are run as root.

          BTW the “unzip” part is also run as root, and a binary package can typically place stuff anywhere in your system (that’s their job after all)… even if you used literal zip files they could still install a script in ways that would cause the OS to execute it.

            Yeah I’m over simplifying on purpose here. The bottom line is piping into sh is dangerous
