Method: File.realpath

Defined in:
file.c

.realpath(pathname[, dir_string]) ⇒ Object

Returns the real (absolute) pathname of pathname in the actual

filesystem not containing symlinks or useless dots.

If _dir_string_ is given, it is used as a base directory
for interpreting relative pathname instead of the current directory.

All components of the pathname must exist when this method is
called.
