How to get/set logical directory path in python
I have a Python script that I run from a symlinked directory, and I call os.getcwd() in it, expecting to get the symlinked path I ran it from. Instead it gives me the "real" path, and in this case that's not helpful. I need it to actually give me the symlinked version.
Does Python have a command for that?
回答1:
Workaround: os.getenv('PWD')
回答2:
In general this is not possible. os.getcwd() calls getcwd(3), and according to POSIX.1-2008 (IEEE Std 1003.1-2008):
The pathname shall contain no components that are dot or dot-dot, or are symbolic links.
os.getenv['PWD'] is shell-dependent and will not work for example with sh from FreeBSD.
