recursion - How can I copy an entire directory in Perl, without using File::Copy::Recursive? -

-

question:

my question pretty identical this 1 here except cannot use file::copy::recursive.

constraints:

i cannot install or modify existing environment, stuck using works. 

use file::copy;   # works! use file::copy::recursive # doesn't work :( use file::path # works!

i error: (i cannot fix error, since user of system, not admin or anything)
can't locate file/copy/recursive.pm in @inc (@inc contains: /path/to/some/place /path/to/other/place .) @ my_program.pl line 13.

scenario:

if helps, scenario want copy contents directory, lets ~/my_dir onto exists here ~/. ~/my_dir has sub-folder ~/my_dir/sub_dir , want copy directory , of it's contents too.

the system's tools way better @ anyway.

system('cp', '-rp', '--', $src, $dst); die("can't launch cp: $!\n") if $? == -1; die("cp killed signal ".($? & 0x7f)."\n") if $? & 0x7f; die("cp exited error ".($? >> 8)."\n") if $? >> 8;

the downside lack of portability. if want portability, install file::copy::recursive. if can install script on machine, can install file::copy::recursive.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
