ulimit

#! /usr/bin/sh
ulimit -n 1024
/usr/bin/ulimit -n 1024

If I put the above to a script(posix shell interpreter), what are the differences?

I should say it clearly, the second ulimit didn't set the nofiles limit.

You are using - #! /usr/bin/sh

so
ulimit -n 1024 is enough.

so there is a builtin function within posix shell and another is just an executable?

One last question. Is there any documentation on this?
