Hi,

the application handles somethings and all users allowed to run the application should be able to change the date and time. So, when the file is created, the owner is one, but I need to update the date and time, according to some rules on the application, and the solution was to use the touch command.Note: everyone that is allowed to run the application, belongs to the same group.

user1 - group app1
user2 - group app1

The process:

user1 creates a file - xxx.txt, today - 20150109 10:10....

tomorrow, the user2 running the application, for example, he accesses the file xxx.txt by the application, so, for my control and my reason, I need to change the date and time. note: if the user1 tries to read the file xxx.txt, it works - the touch command, because the owner is the same.

today, the application issues the touch command with 2 parameters: the date/time and the folder+filename. (parameters: 201501100830 /xxx/yyy/zzz/xxx.txt), the final command is: touch -c -t 201501100830 /xxx/yyy/zzz/xxx.txt

If the solution is to run as root, I will need to do it. Of course, if there is other way to do it, and with safety, I would like to know,

One way to use your script, considering dynamic user, is the application read before the owner, and instead of use the touch command, it would be used your script with 3 parameters: the owner, the date/time and the folder+filename.

would it be a solution? on sudo statement in your script, would the password be requested? if so, it would be not the solution. I need to avoid any interactive session.

if I understood the idea of your script, the folder where the script will be stored, it will be always the same, but the folder and the filename where the date/time will be changed, not.

Please, let me know if it is clear and if there would be a solution for me.

tks.

mkdic

MKDIC(1)						      General Commands Manual							  MKDIC(1)

NAME

       mkdic - Tool for creating a user dictionary

SYNOPSIS

       mkdic [{-cs|-cannaserver} canna-server] [-s] [- | -l local-file] remote-dic

DESCRIPTION

       mkdic  creates  user dictionary named remote-dic in the user dictionary directory of the remote host, on which cannaserver(1M) is in opera-
       tion.  Dictionary file name remote-dic is assigned to this file at this time.

       If the - and -l option isn't specified, mkdic creates an empty dictionary.

       If the - option is specified, the standard input will be used as the dictionary file. If the -l option is  specified,  local-file  will	be
       used as the dictionary file.

       If the user dictionary directory does not exist, it will be created.

       Dictionary  directory  file  -- dics.dir -- is rewritten automatically after the registering. The registered dictionary can thus be used by
       writing the dictionary name into the customize file.

OPTIONS

       -cs canna-server (or -cannaserver canna-server)
		   Specifies the server machine that contains the dictionary to be created.

       -s	   Indicates that the dictionary to be created is an adjunct dictionary.  If this option is omitted, the dictionary will  be  cre-
		   ated as an independent-word one.

       -l local-file
		   Registers the input data from local-file.

       -	   The standard input will be used as the dictionary file.

EXAMPLES(1) If you want to creat an empty dictionary file:

	     % mkdic test(2) If you want to register the input data from the standard input:

	     % mkdic test -

       Registers  the  input data from the standard input, in the user dictionary directory under dictionary name ``test''.  The following line is
       then added to dictionary directory file -- dics.dir -- :

		 user1.t(.mwd) -test-(3) If the dictionary file is specified:

	     % mkdic test -l test1.t

       Registers independent-word dictionary file ``test1.t'' in the remote host's user dictionary directory under dictionary name ``test''.   The
       following line is then added to dics.dir:

		user1.t(.mvd) -test-

       user1.t is a dictionary file name generated automatically by the system.
