You don’t need A GUI FOR SORTING FILES BY SIZE.

The statement#

Find the correct qr code

The solution#

Upon unzipping the attached archive, there are a lot of qr codes with the same file size.

$_ ls -lah

total 4.0M drwxrwxr-x 2 sivaplays sivaplays 36K Dec 9 03:01 . drwxr-xr-x 3 sivaplays sivaplays 4.0K Dec 7 21:01 .. -rw-rw-r– 1 sivaplays sivaplays 535 Oct 9 19:49 fake_qr_100.png -rw-rw-r– 1 sivaplays sivaplays 535 Oct 9 19:49 fake_qr_101.png … -rw-rw-r– 1 sivaplays sivaplays 535 Oct 9 19:49 fake_qr_997.png -rw-rw-r– 1 sivaplays sivaplays 535 Oct 9 19:49 fake_qr_998.png -rw-rw-r– 1 sivaplays sivaplays 535 Oct 9 19:49 fake_qr_999.png -rw-rw-r– 1 sivaplays sivaplays 535 Oct 9 19:49 fake_qr_99.png -rw-rw-r– 1 sivaplays sivaplays 535 Oct 9 19:49 fake_qr_9.png

One file has a different size, so it has to be the flag

$_ ls -lh | rg -v 535

total 4.0M -rw-rw-r– 1 sivaplays sivaplays 528 Oct 9 19:59 fake_qr_669.png
