    I know this is a meme and not GitHub, but I thought some people might like to learn that if you do please shutdown && thanks it won’t say you’re welcome if the shutdown failed

      Wait, isn’t it the other way around? I thought ; only executed the next command if the previous one succeeded, and && executed the next command regardless of exit status.

        Partly right in bash:

        set -e; echo 1; echo 2;

        is the same as

        echo 1 && echo 2

        So if you see the -e in a script, it’s to keep the function clean.

          Ah yes you’re right, had to look it up to see for myself. It’s weird because i remember specifically changing some of my &&s for ; instead because i wanted it to not continue if exit wasn’t zero, but i must’ve misread it at the time. Time to change it back i guess lol.

            It makes more sense if you think of semicolons like other programming languages like Java and C use it.

            foo();
bar();

            But those languages allow foo(); bar(); as well. Then && works like a normal short circuited expression (with side effects).
