truncate
  • truncate FILEHANDLE,LENGTH
  • truncate EXPR,LENGTH
  • Truncates the file opened on FILEHANDLE, or named by EXPR, to the specified length. Produces a fatal error if truncate isn't implemented on your system. Returns true if successful, the undefined value otherwise.

    The behavior is undefined if LENGTH is greater than the length of the file.
