title: find results piped to zcat and then to head
body: <p>I'm trying to search for a certain string in a lot of gziped csv files, the string is located at the first row and my thought was to get the first row of each file by combining find, zcat and head. But I can't get them to work together.</p>
  
  <pre><code>$find . -name "*.gz" -print | xargs zcat -f | head -1
  20051114083300,1070074.00,0.00000000
  xargs: zcat: terminated by signal 13
  
  example file:
  $zcat 113.gz | head
  20050629171845,1069335.50,-1.00000000
  20050629171930,1069315.00,-1.00000000
  20050629172015,1069382.50,-1.00000000
   .. and 2 milion rows like these ...
  </code></pre>
  
  <p>Though I solved the problem by writing a bash script, iterating over the files and writing to a temp file, it would be great to know what I did wrong, how to do it, and if there might be other ways to go about it.</p>
