Shooting yourself in the foot

A timeless classic.

In C it’s extremely easy :)

C pitfalls

Also, mv and rm commands. I once had a bunch of pngs named 1.png, 2.png, etc. But the numbering was in the wrong order, so I wrote a script to fix that:

1
2
3
4
5

mv 1.png 30.png
mv 2.png 12.png
# ...
mv 30.png 5.png
# ...

You can easily spot where it shot me in the foot. More than a half of the pngs were gone 🙂👍. Should’ve used a separate folder, renaming in-place is dangerous.
