juanino / bigls.py

Last active November 7, 2019 02:21

do an ls in a huge dir and print out a shell script to remove. better than shell globbing

	# when you have millions of files
	# this is faster than ls if you don't need the other metadata
	# like mod times or perms

	from os import listdir
	files = listdir(".")

	# here we can output the giant list with some rm commands
	# then you can pipe it to sh -x to perform the operations you wawnt
	# or grep out the noise first
