📝 Posix - Speed up "find" + "exec" command (recursive)

📅 2020-11-08 | ⏰ 0 minutes

I learn some trick today on how to speed up find, exec command. Let check this out:

	# let see how many files we have
	$ find . -type f \| wc -l
	36367

	# lets check every file status
	$ time find . -type f -exec stat {} \; > /dev/null
	real 0m40.107s
	user 0m14.381s
	sys 0m26.410s

	# lets check every file status
	$ time find . -type f -exec stat {} + > /dev/null
	real 0m1.281s
	user 0m0.626s
	sys 0m0.656s

Wow that’s quite a huge difference! Impressive! All we did was swap the \; for a +.
