Full Discussion: Change a file's timestamp
Operating Systems AIX Change a file's timestamp Post 302199657 by rcarnesiii on Tuesday 27th of May 2008 11:51:51 AM
Old 05-27-2008
Sounds like someone is trying to do something fishy "file should appear as if it has not been modified" Smilie . Anyways, I have a question about the modification time for a symbolic link.
Code:
foo.c -> apps/gendev/src/foo.c

the timestamp on apps/gendev/src/foo.c is say 'May 27 11:37'

the timestamp on foo.c (which points to the source file) is 'May 27 10:42' which is when the link was created. Everytime I edit foo.c from my directory the timestamp on apps/gendev/src/foo.c is updated which I understand because I am really modifying that file. I want to know if there is a way to modify the timestamp on the link without relinking the file?

Thanks

PAM_TIMESTAMP_CHECK(8)						 Linux-PAM Manual					    PAM_TIMESTAMP_CHECK(8)

NAME
pam_timestamp_check - Check to see if the default timestamp is valid SYNOPSIS
pam_timestamp_check [-k] [-d] [target_user] DESCRIPTION
With no arguments pam_timestamp_check will check to see if the default timestamp is valid, or optionally remove it. OPTIONS
-k Instead of checking the validity of a timestamp, remove it. This is analogous to sudo's -k option. -d Instead of returning validity using an exit status, loop indefinitely, polling regularly and printing the status on standard output. target_user By default pam_timestamp_check checks or removes timestamps generated by pam_timestamp when the user authenticates as herself. When the user authenticates as a different user, the name of the timestamp file changes to accommodate this. target_user allows to specify this user name. RETURN VALUES
0 The timestamp is valid. 2 The binary is not setuid root. 3 Invalid invocation. 4 User is unknown. 5 Permissions error. 6 Invalid controlling tty. 7 Timestamp is not valid. NOTES
Users can get confused when they are not always asked for passwords when running a given program. Some users reflexively begin typing information before noticing that it is not being asked for. EXAMPLES
auth sufficient pam_timestamp.so verbose auth required pam_unix.so session required pam_unix.so session optional pam_timestamp.so FILES
/var/run/sudo/... timestamp files and directories SEE ALSO
