jot it up

While reading through UNIX powertools tonight, I came across jot. This nifty little utility will print a sequence of numbers, which can be used to iterate through a loop:

for i in `jot 5`; do
    echo $i

Using jot in this way is typically faster than other mechanisms (e.g., i=expr $i+1), and is easier to read IMHO. Jot it up yizos!
