      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).

      alias thanks="You are most welcomed"

      you need to use the echo command if you want to echo something:

      alias thanks="echo 'You are most welcomed'"

      (the inner single-quotes are not strictly required in this case, but recommended nonetheless)
