[Help-bash] parallel processing in bash (to replace for loop)

[Peng Yu]

Hi,

I have see a number of ways to parallelize for loop. However, none of
the methods is syntactically clean and easy (as I would want, maybe
they are good enough for others) to use with bash. I'm wondering what
is the best practice to parallelize a for loop in bash as of now.

E.g:

or gnu parallel
