title: in linux what are ls flags in sftp
body: <p>in linux, we have lots of flags to list files in command  ls. we can't do the same inside sftp commannd. For example, in linux, I can list a file's full time by runnling command: 
  <code>ls --full-time filename</code>
  when I sftp to a server, I can't run command: ls --full-time.</p>
  
  <p>The ls help in sftp doesn't list all available flags. So can you please tell me what are ls flags in sftp? </p>
  
  <p>Thank you!</p>
