Recursively place file in a directory/all subdirectories - rootVIII - Dec-26-2018
Having some fun with recursion.
This one places a file in the specified directory as well as its subdirectories and their subdirectories etc. In other words don't specify the file path to be '/'. hahahaha.... unless you write the code to undo it
#! /usr/bin/python3
from os.path import isdir, basename
from os import listdir, system, getcwd, chdir
import sys
# recursively create a file in all subdirectories of a given
# directory.. all dirs/subdirs should have different names
def get_diff(available, removal):
difference = []
s1 = set()
s2 = set()
s1.update(available)
s2.update(removal)
for i in s1.difference(s2):
difference.append(i)
return difference
def create(finished_folders):
chdir("/home/absolute/path/to/directory")
current_dir = basename(getcwd())
available_dirs = listdir(".")
removal_list = []
for d in available_dirs:
if d in finished_folders or not isdir(d):
removal_list.append(d)
available_dirs = get_diff(available_dirs, removal_list)
if current_dir not in finished_folders:
while len(available_dirs) > 0:
next_dir = available_dirs.pop()
if next_dir not in finished_folders and isdir(next_dir):
chdir(next_dir)
available_dirs = listdir(".")
for directory in available_dirs:
if directory in finished_folders or not isdir(directory):
removal_list.append(directory)
available_dirs = get_diff(available_dirs, removal_list)
system("touch test.txt")
finished_folders += [basename(getcwd())]
create(finished_folders)
else:
print("FINISHED")
sys.exit()
if __name__ == "__main__":
folders = []
create(folders)
RE: Recursively place file in a directory/all subdirectories - Gribouillis - Dec-26-2018
Is this code for the obfuscated python contest? If you want to add an empty 'test.txt' file in every subfolder of a hierarchy, you can do it with
os.walk(). Why use such a complicated function? Even get_diff() can be shorteneddef get_diff(available, removal):
s = set(removal)
return [x for x in available if x not in s]Do you know one can 'touch' without a subprocess? There is a pathlib.Path.touch() method that does just that!
RE: Recursively place file in a directory/all subdirectories - rootVIII - Dec-26-2018
hell yeah looking at pathlib.Path.touch() right now... awesome
Actually I was specifically trying to do it without os.walk()....
