How to get full path of specified hidden files matching pattern recursively - SriRajesh - Jan-18-2020
Hi,
I want to get the full path of hidden files of matching pattern (file name: .daily.log)
The hidden file name: ".daily.log"
from pathlib import Path
for filename in Path('D:\Backupdata\*\*').rglob('*.daily.log'):
print(filename)I am getting below error:OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: 'D:\\Mekala_Backupdata\\*\\*'

Files which starts with a dot are not hidden on Windows-Systems.
The meaning of the dot comes from the unix world.
MS uses instead attributes, which are not easy accessible.
If a file is hidden or not, should not be any problem für Python.
This is not a valid path
Path('D:\Backupdata\*\*').You can't use a wildcard in a Path, but
glob and rglob can do this.If you have the file .daily.log in different paths, you could use
rgblob without a wildcard.from pathlib import Path
for filename in Path('D:\Backupdata').rglob('.daily.log'):
print(filename)This code will find also a .daily.log in D:\Backupdata\To prevent this, you can calculate how deep a file is in the root path.
A more flexible function:
from pathlib import Path
def my_constraint(file, depth):
"""
Returns True, if depth == 2
On the same level, is level 1
One directory deeper, is level 2
...
"""
return depth == 2
def recursive_search(root, pattern, constraint=None):
root = Path(root)
for file in root.rglob(pattern):
if constraint:
depth = len(file.parts) - len(root.parts)
if constraint(file, depth):
yield file
else:
yield file
# no constraint
generator = recursive_search(r"D:\Backupdata", ".daily.txt")
for file in generator:
print(file)
# with constraint
generator = recursive_search(r"D:\Backupdata", ".daily.txt", my_constraint)
for file in generator:
print(file)

I want to check in the Linux system.
RE: How to get full path of specified hidden files matching pattern recursively - DeaD_EyE - Jan-18-2020
Your posted error code was a
OSError: [WinError 123]The path you've used is a path for Windows systems.
On a linux system you don't have a drive letter.
All absolute paths begins at
/ (the root directory).Usually you run on linux your scripts as a user like on Windows.
So your Backupdata could be in /home/your_user_account/Backupdata
(On Windows it is C:\Users\your_user_account\Backupdata)
Using the pathlib, allows you to handle paths on windows, mac and linux in right way.
If you want to make your script os independent with the use of Path:
my_backup_dir = Path.home() / "Backupdata"If your user home directory is named for example
FooBar,then the resulting directory on Linux is: /home/FooBar/Backupdata
And on Windows: C:\Users\FooBar\Backupdata

Thanks. Got it.
