Find all “*.wav” files that created yesterday on linux host with python. - pydeev - Dec-29-2019
There is so many .wav files and create alot of these files everyday on Linux Host. I want to find all wav files that created yesterday ( a day ago when script run )on subdirectories and convert them to mp3 format with python script. I run os.walk ( path ) for finding '.wav' files but can not check that they was create yesterday.
for root, dir, files in os.walk(path): for file in files: if file.endswith('.wav'): wav = root + '/' + str(file) cmd = 'lame --preset insane %s' % wav subprocess.call(cmd, shell=True)Your answers can help alot.Thanks in advance

This will walk from starting path:
from pathlib import Path def walk_dir(starting_dir): flist = [] for path in Path(starting_dir).iterdir(): if path.is_file(): if path.suffix == '.wav': print(path) flist.append(path) elif path.is_dir(): walk_dir(path) for file in flist: print(file) if __name__ == '__main__': start_path = '/home/' walk_dir(start_path)

Use os.stat() to check when files is created.
Make a yesterday date object and compare.
Example.
from datetime import date, timedelta from pathlib import Path path = Path('some.wav') yesterday = date.today() - timedelta(days=1) timestamp = date.fromtimestamp(path.stat().st_mtime) if yesterday == timestamp: print('Do something file is from yesterday') RE: Find all “*.wav” files that created yesterday on linux host with python. - pydeev - Jan-01-2020
tnx Larz60+ for your reply
i have a question , that my files are so much ( about 5-6 thousand of WAV files and about 25-30 GB ) . because of that if i save that file to a list , is there inefficient for using list?
sorry for my bad English

i have some randome folder on my path ( like /archive_sounds/Trunk/* and within this folders ( * ) , there is WAV files. by this how can i use path for finding these files.
thanks so much

Example mine and @Larz60+,can also trow in subprocess call as you have in first code.
Here doing all in loop,so not saving to a list.
from pathlib import Path from datetime import date, timedelta import subprocess from os import fspath def walk_dir(starting_dir): #flist = [] yesterday = date.today() - timedelta(days=66) for path in Path(starting_dir).iterdir(): timestamp = date.fromtimestamp(path.stat().st_mtime) if path.is_file() and yesterday == timestamp: print(fspath(path)) out = subprocess.run(['ls', '-l', fspath(path)], capture_output=True) print(out.stdout.decode()) #print(path) if path.is_dir(): walk_dir(path) if __name__ == '__main__': start_path = r'E:\div_code\sound_folder' walk_dir(start_path)
Output:E:\div_code\sound_folder λ python find_files.py E:\div_code\sound_folder\hello_vs.txt -rw-r--r-- 1 Tom 197121 5 Oct 27 01:49 E:\div_code\sound_folder\hello_vs.txt E:\div_code\sound_folder\Ny mappe\in_folder.txt -rw-r--r-- 1 Tom 197121 15 Oct 27 01:58 E:\div_code\sound_folder\Ny mappe\in_folder.txt.txt could of course be .wav 66-days old in sound_folder*(also files in all sub-folders).If files is in this case are 66-days old run:
ls -l filename # Displays size, data of the specified file

thanks every one
finally i resolve that
def walk_dir(starting_dir): flist = [] yesterday = datetime.date.today() - datetime.timedelta(days=0) for path in pathlib.Path(starting_dir).iterdir(): timestamp = datetime.date.fromtimestamp(path.stat().st_mtime) if path.is_dir() and yesterday == timestamp: print(" We Are Here : ", path) for test in pathlib.Path(path).iterdir(): print("hiiiiiiiiiiiiiiiiiiiiiiiiiii", test) if test.suffix == '.wav': flist.append(test) print(flist) for file in flist: subprocess.call('lame --preset insane %s' % file, shell=True) for pathh in pathlib.Path(starting_dir).iterdir(): timestampp = datetime.date.fromtimestamp(pathh.stat().st_mtime) if pathh.is_dir() and yesterday == timestampp: for tes in pathlib.Path(pathh).iterdir(): print("We Are Here Again : ", pathh) if str(pathh) == str(TEST_DIR + yesterdays.strftime('%Y-%m-%d')): break if tes.suffix == '.mp3': print("This Is MP3 File : ", tes) # t = str(pathh.abspath(os.path.join(starting_dir, tes))) mine = os.path.abspath(tes) shutil.move(mine, TEST_DIR + yesterdays.strftime('%Y-%m-%d') + '/')
