Find all “*.wav” files that created yesterday on linux host with python.

[pydeev]

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')

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

Thanks snippsat
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

Appending 6000 times to a list will cost you a fraction of a millisecond for the whole process. This is negligible as compared to the time needed to scan the file system with stat calls.

You do it bye combine code you have gotten til now.
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

So here will find all files .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') + '/')
