Check if file is symlink in python
To determine if a directory entry is a symlink use this:
os.path.islink(path)
Return True if path refers to a directory entry that is a symbolic link. Always False if symbolic links are not supported.
For instance, given:
drwxr-xr-x 2 root root 4096 2011-11-10 08:14 bin/
drwxrwxrwx 1 root root 57 2011-07-10 05:11 initrd.img -> boot/initrd.img-2..
>>> import os.path
>>> os.path.islink('initrd.img')
True
>>> os.path.islink('bin')
False
For python 3.4 and up, you can use the Path class
from pathlib import Path
# rpd is a symbolic link
>>> Path('rdp').is_symlink()
True
>>> Path('README').is_symlink()
False
You have to be careful when using the is_symlink() method. It will return True even the target of the link is non-existent as long as the the named object is a symlink. For example (Linux/Unix):
ln -s ../nonexistentfile flnk
Then, in your current directory fire up python
>>> from pathlib import Path
>>> Path('flnk').is_symlink()
True
>>> Path('flnk').exists()
False
The programmer has to decide what he/she realy wants. Python 3 seems to have renamed a lots of classes. It might be worthwhile to read the manual page for the Path class: https://docs.python.org/3/library/pathlib.html
Without the intention to bloat this topic, but I was redirected to this page as I was looking for symlink's to find them and convert them to real files and found this script within the python tools library.
