You need to be very fast to not copy your file - the -u, --update option, copies "only when the SOURCE file is newer than the destination file or when the destination file is missing". You'd need to copy twice within a minute to hit a file with the same name older than your actual one.

Hi,
I have the following question :
As far as I know unix doesn't store file creation dates.
Would that imply the following?
tar -cvzf backup.tar --newer
is equal to:
tar -cvzf backup.tar --newer-mtime ? (1 Reply)

zipdetails
ZIPDETAILS(1p) User Contributed Perl Documentation ZIPDETAILS(1p)
NAME
zipdetails - display the internal structure of zip files
SYNOPSIS
zipdetaile [-v] zipfile.zip
zipdetails -h
DESCRIPTION
Zipdetails displays information about the internal record structure of the zip file. It is not concerned with displaying any details of the
compressed data stored in the zip file.
The program assumes prior understanding of the internal structure of a Zip file. You should have a copy of the Zip APPNOTE file at hand to
help understand the output from this program ("SEE ALSO" for details).
OPTIONS
-v Enable Verbose mode
-h Display help
By default zipdetails will output the details of the zip file in three columns.
Column 1
This contains the offset from the start of the file in hex.
Column 2
This contains a textual description of the field.
Column 3
If the field contains a numeric value it will be displayed in hex. Zip stored most numbers in little-endian format - the value
displayed will have the little-endian encoding removed.
Next, is an optional description of what the value means.
If the "-v" option is present, column 1 is expanded to include
o The offset from the start of the file in hex.
o The length of the filed in hex.
o A hex dump of the bytes in field in the order they are stored in the zip file.
TODO
Error handling is still a work in progress. If the program encounters a problem reading a zip file it is likely to terminate with an
unhelpful error message.
SEE ALSO
The primary reference for Zip files is the "appnote" document available at <http://www.pkware.com/documents/casestudies/APPNOTE.TXT>.
An alternative is the Info-Zip appnote. This is available from ftp://ftp.info-zip.org/pub/infozip/doc/ <ftp://ftp.info-
zip.org/pub/infozip/doc/>
The "zipinfo" program that comes with the info-zip distribution (http://www.info-zip.org/ <http://www.info-zip.org/>) can also display
details of the structure of a zip file.
