Programming Perl, 4th Edition

symlink

symlink OLDNAME, NEWNAME

This function creates a new filename symbolically linked to the old filename. The function returns true for success, and false otherwise. On systems that don’t support symbolic links, it raises an exception at runtime. To check for that, use eval to trap the potential error:

$can_symlink = eval { symlink("",""); 1 };

Or use the Config module. Be careful if you supply a relative symbolic link, since it’ll be interpreted relative to the location of the symbolic link itself, not to your current working directory.
