  • Find[ stream , " text "] finds the first line in an input stream that contains the specified string.
  • Find[ stream , " ", " ", ... ] finds the first line that contains any of the specified strings.
  • Find breaks the input stream into records, delimited by record separators, and scans each record for the strings you specify.
  • Find returns as a string the first record which contains the specified text.
  • If Find does not find any record which contains the specified text before it reaches the end of the file, it returns EndOfFile.
  • The following options can be given:
  • The first argument to Find can be InputStream[" name ", n ], or simply " name " if there is only one open input stream with the specified name.
  • You can open a file or pipe to get an InputStream object using OpenRead.
  • Find does not close streams after it finishes reading from them.
  • See the Mathematica book: Section 2.11.8.
