@cheddar Do you want to take a look and tell me what you think? Thanks!
Especially in bash, use longer variable names please.  As it is, Bash is often a cryptic scripting language, when you are approaching a new script and you don't know what it does and you are confronted with short variable names like this, it greatly decreases readability.
