Small, useful helper scripts that I've gotten tired of rewriting every time I need them.
rand.sh - Outputs random numbers. Uses od and urandom. Usage is sh rand.sh min max or just sh rand.sh max.
math.sh - Outputs result of mathematical equation. Uses bc. Usage is sh math.sh "equation" decimals
shell.sh - A boiler-plate script that has code for requiring root and handling parameters. (Doesn't actually work at the moment...)
