       err  FD information error (see NAME column);

       jld  jail directory (FreeBSD);

       Mxx  hex memory-mapped type number xx.

       tr   kernel trace file (OpenBSD);

       txt  program text (code and data);

       v86  VP/ix mapped file;



  FD  is  followed  by one of these characters, describing the

  mode under which the file is open:



       r for read access;

       w for write access;

       space if mode unknown and no lock

        character follows;

       '-' if mode unknown and lock

        character follows.



  The mode character is followed by one of these lock  charac-

  ters, describing the type of lock applied to the file:



       N for a Solaris NFS lock of unknown type;

       r for read lock on part of the file;

       R for a read lock on the entire file;

       w for a write lock on part of the file;

       W for a write lock on the entire file;

       u for a read and write lock of any length;

       U for a lock of unknown type;

       x  for an SCO OpenServer Xenix lock on part  of the

  file;

  file;

       space if there is no lock.
