> The 'cd' man page says that 'cd -P' should "perform actions equivalent to the > chdir() function". Just wondering, do you know what is the function called by `cd`/`cd -L` then? It doesn't seems to be a bash internal tweak because `/usr/bin/pwd -L` is able to get the symlink path, and this binary is not part of bash. > You'll have to make a case for it being useful enough to add. The use case is for shells written in Python, like for instance `xonsh` [1,2]. Being powered by Python, the only way to change directory is by using `os.chdir()`. It is then not possible to mimic the bash `cd` function without using workarounds, like for instance storing the symlink path in a variable, and even this doesn't allow to use `/usr/bin/pwd -L` in scripts because it would always returns the physical location. Having such described functions (yet to be named) would permit python shells to offer users differentiated `cd` and `cd -P` commands, as well as having `pwd -L` in scripts behaving the same than in traditional shells.
