title: Force push a git lfs file ID
body: <p>Using git lfs, how can I force push a file ID that I know I have locally but that for some reason did not get pushed to the server ?</p>
  
  <p>ie, on my build system I have errors like </p>
  
  <blockquote>
    <p>Git LFS: (0 of 15 files, 1 skipped) 0 B / 1.10 MB, 4.30 MB skippedGit LFS: (15 of 15 files, 1 skipped) 1.10 MB / 1.10 MB, 4.30 MB skipped
    [f54812afe7bfdff14c154af6adb7cc4cb425763c1bdaa5fcf0bcea4fd2da7ab9] Object does not exist on the server: [404] Object does not exist on the server</p>
  </blockquote>
  
  <p>So I know I just need to push this file whose ID is <code>f5481...</code> but what's the command to do that ? <code>git lfs push</code> doesn't work I have to force the sync on that specific file ID</p>
  
  <p>I remember finding that magic command once lost in some github issue but I have lost it and the man documentation doesn't seem to be helpful...</p>
