truename -- determine the real name of a file.
truename [-equiv] [-verbose]<path> <path>...]
truename computes the true names of paths given to it, by expanding
all path components that are symlinks and eliminating all components
that are '.' of '..'. In normal operation,
truename prints nothing
if a path does not exist. In equivalence class mode (-equiv),
truename prints all paths equivalent to the given one (and
including neither '.' nor '..') regardless of whether the final target
exists or not.
Print the traversal history of how results were constructed.
This allows one to understand bizarre results.
Print all equivalent paths for the given paths, ignoring
'.' and '..' components. This gives an idea of where
each path should point, whether it exists or not.
It also allows one to check whether two symlinks that
do not exist point to the same (nonexistent) place.
