title: why does count line shows 0 while file file size if great than 1G?
body: <p>I have a large csv file about 5G. i want to split it into smaller files to be imported into sqlite.</p>
  
  <pre><code>`split -b 1G input.txt output`
  </code></pre>
  
  <p>i got 6 output files from running the above code: output1-output6. the problem is that only output1 has 300K records and all other files have 0. i used the following to count lines in each file: </p>
  
  <pre><code>`wc -l output1`
  </code></pre>
  
  <p>but when i check the output file size, all of them are around 1G (except output6). What's wrong with my code or file? </p>
