i know the problem you are haveing. because i had it.
1) i archive by day.
2) most files have a time stamp to the sec. (still dosnet help)
3) i use a microsec at the end of the file name. (now 1 in a million chance of haveing the same name.
so if you test the existance of the current filename in your archive dir. and move it to the archive dir w/ a microsec at the end of it you will be all good.
this is the code for a 6 digit microsec it is in c.
I am really really new to Unix. I'm lost with so many books around for different shell. I'm thinking of taking a course on Operating Systems but it contains a lot of Unix programming I think. For example, someone was talking about a "which" command. But I wasn't able to figure out what it does...... (10 Replies)

gettimeofday
gettimeofday(2) System Calls Manual gettimeofday(2)Name
gettimeofday, settimeofday - get or set date and time
Syntax
#include <sys/time.h>
gettimeofday(tp, tzp)
struct timeval *tp;
struct timezone *tzp;
settimeofday(tp, tzp)
struct timeval *tp;
struct timezone *tzp;
Description
The system call returns the system's notion of the current Greenwich time and the current time zone. Time returned is expressed relative
in seconds and microseconds since midnight January 1, 1970.
The structures pointed to by tp and tzp are defined in <sys/time.h> as:
struct timeval {
long tv_sec; /* seconds since Jan. 1, 1970 */
long tv_usec; /* and microseconds */
};
struct timezone {
int tz_minuteswest; /* of Greenwich */
int tz_dsttime; /* type of dst correction to apply */
};
The timezone structure indicates the local time zone (measured in minutes of time westward from Greenwich), and a flag that, if nonzero,
indicates that Daylight Saving time applies locally during the appropriate part of the year.
Only the superuser can set the time of day.
Return Values
A 0 return value indicates that the call succeeded. A -1 return value indicates an error occurred, and in this case an error code is
stored into the global variable errno.
Diagnostics
The call fails under the following conditions:
[EFAULT] An argument address referenced invalid memory.
[EPERM] A user other than the superuser attempted to set the time.
