change created and modification time if symbolic links

Hi,

I am trying to duplicate a symbolic link, the new link should be the exact replica of the original one, with same file attributes, permissions, owner, group and even the time.

i m successful in changing the owner and group, but when i try to change the time using utime, the time of the file which is pointed to by this link get updated.

for example, there is file1 and file1_link is a symbolic link to file1. something like this:

lrwxrwxrwx 1 avni avni 5 Feb 27 11:44 file1_link -> file1
-rw-rw-rw- 1 avni avni 2061 Feb 26 18:47 file1


now i have to duplicate file1_link so that i have

lrwxrwxrwx 1 avni avni 5 Feb 27 11:44 file1_link_dup -> file1

but instead i get
lrwxrwxrwx 1 avni avni 5 Feb 28 11:30 file1_link_dup -> file1

when is do utime for file1_link_dup the result is something like this:
lrwxrwxrwx 1 avni avni 5 Feb 27 11:44 file1_link -> file1
-rw-rw-rw- 1 avni avni 2061 Feb 27 11:44 file1
lrwxrwxrwx 1 avni avni 5 Feb 28 11:30 file1_link_dup -> file1


can any body tell how this can be achieved.
I read about lutimes, but its not on my system.


I am new to UNIX and hence have little knowledge of the various distributions and commands available.


Thanks in advance.

CHGRP(1)						    BSD General Commands Manual 						  CHGRP(1)

NAME
chgrp -- change group SYNOPSIS
chgrp [-fhvx] [-R [-H | -L | -P]] group file ... DESCRIPTION
The chgrp utility sets the group ID of the file named by each file operand to the group ID specified by the group operand. The following options are available: -H If the -R option is specified, symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed.) -L If the -R option is specified, all symbolic links are followed. -P If the -R option is specified, no symbolic links are followed. This is the default. -R Change the group ID for the file hierarchies rooted in the files instead of just the files themselves. -f The force option ignores errors, except for usage errors and does not query about strange modes (unless the user does not have proper permissions). -h If the file is a symbolic link, the group ID of the link itself is changed rather than the file that is pointed to. -v Cause chgrp to be verbose, showing files as the group is modified. If the -v flag is specified more than once, chgrp will print the filename, followed by the old and new numeric group ID. -x File system mount points are not traversed. The -H, -L and -P options are ignored unless the -R option is specified. In addition, these options override each other and the command's actions are determined by the last one specified. The group operand can be either a group name from the group database, or a numeric group ID. If a group name is also a numeric group ID, the operand is used as a group name. The user invoking chgrp must belong to the specified group and be the owner of the file, or be the super-user. FILES
/etc/group group ID file EXIT STATUS
The chgrp utility exits 0 on success, and >0 if an error occurs. COMPATIBILITY
In previous versions of this system, symbolic links did not have groups. The -v and -x options are non-standard and their use in scripts is not recommended. SEE ALSO
chown(2), fts(3), group(5), passwd(5), symlink(7), chown(8) STANDARDS
The chgrp utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. BSD
