juanino / py big ls
Last active Nov 6, 2016
do an ls in a huge dir and print out a shell script to remove. better than shell globbing
View py big ls
# 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
You can’t perform that action at this time.
