Be careful, this is Net::SFTP::Foreign, not Net::SFTP. They are very
similar, but there are differences. For instance the ls method
returns an arrayref, not a list in Net::SFTP::Foreign. This means
your code should be
my @files = @{
$sftp->ls($remote_dir, wanted => sub { S_ISREG($_[1]->{a}->perm)})
};
from perldoc Net::SFTP::Foreign
$sftp->ls($remote, %opts)
Fetches a directory listing of the remote directory $remote. If
$remote is not given, the remote current working directory is
listed.
Returns a reference to a list of entries. Every entry is a refer$B!>(B
ence to a hash with three keys: "filename", the name of the entry;
"longname", an entry in a "long" listing like "ls -l"; and "a", a
Net::SFTP::Foreign::Attributes object containing file atime, mtime,
permissions and size.
from perldoc Net::SFTP
$sftp->ls($remote [, $subref ])
Fetches a directory listing of $remote.
If $subref is specified, for each entry in the directory, $subref will
be called and given a reference to a hash with three keys: filename,
the name of the entry in the directory listing; longname, an entry in a
"long" listing like "ls -l"; and a, a Net::SFTP::Attributes object,
which contains the file attributes of the entry (atime, mtime, permis$B!>(B
sions, etc.).
If $subref is not specified, returns a list of directory entries, each
of which is a reference to a hash as described in the previous para$B!>(B
graph.
