in reply to Collapsing paths

if you are interested in doing it with regexp: 
{ $path =~ s{(^|/)(\w+/\.\./|\./)}{$1} and redo }

[download]
which collapses ./ and <dir>/../

    It wouldn't hurt to make the loop more obvious. 

    1 while $path =~ s{(^|/)(\w+/\.\./|\./)}{$1};

    It's even shorter.
