cheat of for/if

[shigemk2]

When writing shell script, I often use "if" or "for".
But I forget the usages of them because OFTEN use them.

So, I want to add if/for on this repository.
Just like this executing "cheat for":

# loop specified number of times
for i in `seq 1 N`
do
  …
done

What do you think about this?
