Nice way to get me to look up your docs on how to search files! My first attempt managed to hardlock the game:
for(let i=0; i<=8; i++) for(let j=0; j<=8; j++) for(let k=0; k<=8; k++) for(let l=0; l<=8; l++) ls ${i}/${j}/${k}/${l}
for(let i=0; i<=8; i++) for(let j=0; j<=8; j++) for(let k=0; k<=8; k++) for(let l=0; l<=8; l++) ls ${i}/${j}/${k}/${l}
for(var i=0;i<8;i++) ls ${i}
for(var i=0;i<2;i++) for(var j=0;j<2;j++) for (var k=0;k<2;k++) for (var l=0;l<2;l++) ls ${i}/${j}/${k}/${l}
This did nothing, so I'm not sure if you fixed it or just placed a cap on how much js you are executing... (should have at least shown 16 frames)
for(var i=0;i<8;i++) for(var j=0;j<8;j++) for (var k=0;k<8;k++) for (var l=0;l<8;l++) open ${i}/${j}/${k}/${l}
Is/was producing a nice log of things not opened...of course my browser tab is busy logging 6 GB+ of history (does your terminal have a scrollback limit?)
Cute game, maybe I'll try to open the box later after I get some sleep. Not sure what I would use the terminal for, though - is basically what you're trying to do an interactive scratchpad with history?
If that's the case, I would look into Jupyter e.g., I'm not sure I get the point otherwise.
I'm honestly not sure if the web sandbox I made has enough realism to solve that puzzle though programming. There is a feature of snail that I was using to get past it.
