Re: Getting the absolute path of a script, without PWD

bash's pushd (and to list, dirs command) seems to track as a LIFO, the specified path to perceived pwd - i.e., the path actually used via series of cds (the only information that can solve this problem of state*). Cwd::Ext appears to do something similar. Unfortunately, there are no useful modules for you to leverage this behavior of pushd via bash. Maybe a useful module to create would be Bash::Pushd::Pwd or something like that.

`Cwd::Ext`'s `abs_path_nd` uses `Cwd`'s `cwd` so it still resolves symlinks for retrieving "the current directory" part.	[reply]
