$realpath(<filepath>)
Useful if you want to find the absolute path of filename with '.' or '..' or symbolic links in it.
The absolute path equivalent of <filepath>
If /home is a symbolic link to /usr/home, and /usr/local is a link to /local, then
$realpath(/home/../local/src) returns "/local/src" (/home -> /usr/home .. -> /usr local -> /local src -> /local/src)
