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.

guards

GUARDS(1)						User Contributed Perl Documentation						 GUARDS(1)

NAME

       guards - select from a list of files guarded by conditions

SYNOPSIS

       guards [--prefix=dir] [--path=dir2:dir2:...] [--default=0|1]	   [-v|--invert-match] [--list|--check] [--config=file]        symbol ...

DESCRIPTION

       The script reads a configuration file that may contain so-called guards, file names, and comments, and writes those file names that satisfy
       all guards to standard output. The script takes a list of symbols as its arguments. Each line in the configuration file is processed
       separately. Lines may start with a number of guards. The following guards are defined:

	   +xxx Include the file(s) on this line if the symbol xxx is defined.

	   -xxx Exclude the file(s) on this line if the symbol xxx is defined.

	   +!xxx Include the file(s) on this line if the symbol xxx is not defined.

	   -!xxx Exclude the file(s) on this line if the symbol xxx is not defined.

	   - Exclude this file. Used to avoid spurious --check messages.

       The guards are processed left to right. The last guard that matches determines if the file is included. If no guard is specified, the
       --default setting determines if the file is included.

       If no configuration file is specified, the script reads from standard input.

       The --check option is used to compare the specification file against the file system. If files are referenced in the specification that do
       not exist, or if files are not enlisted in the specification file warnings are printed. The --path option can be used to specify which
       directory or directories to scan.  Multiple directories are separated by a colon (":") character. The --prefix option specifies the
       location of the files.
