A small (112 bytes) 64bit cat program written in assembly for my amusement.
scat32.asm contains a 32bit version that uses sendfile with the limitations that implies which results in a 58 byte executable.
scat [filename]
If an error occurs it should™ just not print anything.
nasm -f bin scat.asm
Q: Why is it called Small Cat?
A: Because it's small. And because it's funny.
