title: How to break down such a file in UNIX?
body: <p>I have a master file containing the content of 3696 files in it. Each file has a repetitive structure: It starts by a line containing the file name in a quotation from, and ends with <code>.</code>  There is no other repetitions in the files. Is there any way to break down the master file into these smaller files?
  For instance if the master file contains two files as follows,</p>
  
  <pre><code>    "features/mmjr0_si2166.rec"
  0 1800000 L104 -755.825928

  <p>I want them to be separated, and both stored in the directory "features" the first file with the name mmjr0_si2166.rec and the second file mesd0_si1002.rec</p>
