Check if file exists
I need to check whether a file exists and has been changed.



The file should contain a specific string. The file should also have been changed within the last ten seconds.


How do I do that?

NAME

       PCK, pck - map between PCK and character set

DESCRIPTION

       PCK stands for PC Kanji code. It is also known as Shift-JIS  (MS kanji) code. This manual page shows map between  PCK and character set.

       PCK  allocates  the  first  byte  of  each  kanji  code	which corresponds to JIS X0208-1990 and so on to the code other than code range of
       0x00-0x7f and 0xa1-0xdf. The following is a map table for PCK and character set.

       +-----------------------------------------------------------+
       |PCK			      character set		   |
       |0x00 - 0x19		      JIS  X  0201-1976  function  |
       |			      character set		   |
       |0x20			      JIS X 0201-1976 space char-  |
       |			      acter			   |
       |0x21 - 0x7e		      JIS  X   0201-1976   figure  |
       |			      character   set  for  roman  |
       |			      character 		   |
       |0x7f			      JIS X 0201-1976 erase char-  |
       |			      acter			   |
       |0xa1 - 0xdf		      JIS   X	0201-1976  figure  |
       |			      character set for  katakana  |
       |			      (except	for  an  area  of  |
       |			      undefined character  E/0	-  |
       |			      F/14)			   |
       |0x8140 - 0x817e 	      JIS  X  0208-1990  (1 ku	1  |

       |0x9f9f - 0x9ffc 	      JIS X 0208-1990  (62  ku	1  |
       |			      ten - 62 ku 94 ten)	   |
       |0xe040 - 0xe07e 	      JIS  X  0208-1990  (63 ku 1  |
       |			      ten - 63 ku 63 ten)	   |
       |       :				   :		   |
       |       :				   :		   |

       The differences from character set of Japanese EUC are,

	 o  Character  set  of	Japanese  EUC codeset 3 (JIS X 0212-1990) is not assigned except a part of Vender Defined Character (IBM extension
	    character) (see NOTES).

	 o  Character set which corresponds to Japanese EUC C1 control code is not assigned.

NOTES

       In PCK area below has special meaning.

       +---------------------------------------------------------------------------+
       |PCK		     area of character set   meaning			   |
       |0x8740 - 0x879e      JIS X 0208-1990 13 ku   Vender Defined Character	   |
       |					     (special symbols)		   |
       |0xeb40 - 0xecfc 			     Invalid			   |
       |0xed40 - 0xeffc 			     Vender Defined Character	   |
       |					     (IBM extension character NEC  |
       |					     selected)			   |
       |0xf040 - 0xf9fc 			     User Defined Character	   |
       |					     1 ku - 20 ku		   |
       |0xfa40 - 0xfcfc 			     Vender Defined Character	   |
       |					     (IBM extension character)	   |
