There is one thing that aliases can do that functions cannot - and that is control how the rest of the statement is parsed. This can be exploited to write an alias for find that calls a function with globbing temporarily turned off for the rest of the statement; the function then restores globbing state after executing the real find under the hood. http://www.chiark.greenend.org.uk/~sgtatham/aliases.html But yes, other than cool hacks like that, functions are almost always hands down more powerful than aliases. - -- Don't work too hard, make some time for fun as well!
