Bash is a language =)  It has "if" and "for" and functions and variables!

(even if it's not a very good language.  Let's say you have the name of 
a file you need to remove, stored in a variable?  This is how:
     rm -- "$VARIABLE"
Every use of a variable must be surrounded in double-quotes unless you 
have considered the consequences of splitting it by the value of IFS and 
decided this to be safe and desirable.  `man rm` explains "--", a 
feature which most but not all shell commands offer.  And (depending on 
your risk model) what if PATH is odd and contains an `rm` binary that 
does something else?  Robustness/security is always complicated, but 
most languages don't have this sort of pitfall =)
