Welcome, nayaksan!

The solution to your problem, as I understand it, does not require Perl and you can do several things to solve it. However, if you are a limited sudoer on the remote host, you may not be able to solve the problem at all if you can't copy the file owned by wsl to someplace you as user id can access it.

Here is what seems the easiest way to me: log on to the remote host, then do whatever it takes to copy the desired file to your home directory there. If and only if that is possible: back on the local host, execute:

$ scp id@remotehost:filename.suf . # <= note the dot (period)

and the system should ask for your password and the copy should work.

Hope that helps.

Update: I think salva has pointed you in the right direction.
