i'll start with one of my scariest moment when i was like just got started with git cli. around 5-6 years ago, i was assigned on a project with 3 other developers. we had read/write access to Dev repo. i created a branch for my work and tried taking pull from dev repo. team was treating me like an alien(coz i was new) so i googled how to take pull.
found lots and tried one by one. one nonsense user on stackoverflow caught my attention(dont know why lol..) i copied the command and ran it. unfortunately it worked and i got Warning Email next day because all other branches were deleted.
this was the scariest moment of my life as a coder! whats yours ?
