Agreed. And most of the time a script in bash is going to do something
grep blah /from/file | cut -f 1 -d ' ' | uniq | sort
Python generators happen to be very efficient at recreating this sort of
thing entirely in python. A great presentation that all system
programmers should read is found here:
Very cool stuff. Grep is just a generator function. cut is just a
generator function, and so on. And it can be pretty darn fast too.
