[Ssh-sftp-perl-users] About sftp->ls method

[Rajnikant <raj...@pe...>]

Hello everyone,
 
I'm using sftp->ls method to see files on remote location. Following files
are present on remote location:
5.txt, 4.txt, 3.txt, 2.txt, 1.txt
 
Is there possibility that I'll get sftp->ls out put as 
5.txt
4.txt
--
--
1.txt
 
Can I have sorted sftp->ls out put? Out put I want is:
1.txt
--
--
4.txt
5.txt
 
Thanks in advance.

As far as I know, $sftp->ls() (where $sftp IS_A Net::SFTP object)
returns a list of hash references and there are no options of
pre-sorting that list.
But no one stops you from iterating over the list, extracting the names
and sorting them in any way you like.
So the answer to your questions is "yes" - but the way to get there is
possibly not as convenient as you'd hoped ;-)

PS: Another option would be to use do_opendir($path) and then use a
readdir-loop directly on the dir handle, fetching all filenames and
sorting them afterwards.

PPS: Yet another method: Use Net::SSH2, execute a shell command ("ls"
with the necessary switches) and capture and parse the output.

I use this:

@$files_in_directory = $sftp->ls($remote_server_directory);

foreach (@$files_in_directory) {
  $longlist = $_->{longname};
  $shortname = $_->{filename};
  print "longname = $longname}\n";
  print "shortname = $shortname\n";

  if ($shortname =~ /txt/) {
     push @arrivals, $shortname;
  }
}

Then sort @arrivals any way you want.

Hope this helps.

Russ
