I don't have any idea what these things do but the problem I often run into is reasonable
time performance, usually due to memory access patterns when I exceed physical memory
limits. PERL is great if bash doesn't work but sometimes both can get very slow.
( I have found various tricks, such as an "irrelevant" call to bash sort prior to doing
anything as this can prevent thrashing later but IIRC )
I usually just end up taking a single include file for my homebrew command line interface 
and write a one page c++ program that is usually just an STL container or a special relative ( something
that knows my memory access patterns and only supports a subset of, say, vector )
and some specialized processing ( sometimes odd floating point or string processing)
that is probably hard to generalize for a compiled, non-general purpose language.
