How to compare a file by its timestamp and store in a different location whenever timestamp changes?
Hi All,
I am new to unix programming. I am trying for a requirement and the requirement goes like this.....
I have a test folder. Which tracks log files. After certain time, the log file is getting overwritten by another file (randomly as the time interval is not periodic). I need to preserve all the log files in a different folder with the timestamp before it gets overwritten.
Ex:
The log file contents and size varies with time
test/test1.log - 07/22/2011 13:01:11 ; 2 MB
test/test1.log - 07/22/2011 13:27:12 ; 2 MB
test/test1.log - 07/22/2011 14:27:09 ; 1.5 MB
I need to create a archive folder and preserve all these 3 files with their time stamp.
archive/test1.log_20110722130111
archive/test1.log_20110722132712
archive/test1.log_20110722142709
Any help on this is highly appreciated..

doveadm-log
DOVEADM-LOG(1) Dovecot DOVEADM-LOG(1)
NAME
doveadm-log - Locate, test or reopen Dovecot's log files
SYNOPSIS
doveadm [-Dv] log errors
doveadm [-Dv] log find [directory]
doveadm [-Dv] log reopen
doveadm [-Dv] log test
DESCRIPTION
The doveadm log commands are used to locate and reopen the log files of dovecot(1). It's also possible to test the configured targets of
the *log_path settings.
OPTIONS
Global doveadm(1) options:
-D Enables verbosity and debug messages.
-v Enables verbosity, including progress counter.
COMMANDS
log errors
doveadm log errors
The log errors command is used to show the last - up to 1,000 - errors and warnings. If no output is generated, no errors have occurred
since the last start.
log find
doveadm log find [directory]
The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages. If dovecot(1) logs its
messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log
files.
log reopen
doveadm log reopen
This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings. These settings
are configured in /etc/dovecot/conf.d/10-logging.conf.
This is for example useful after manually rotating the log files.
log test
doveadm log test
This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files. The used prior-
ities are: debug, info, warning, error and fatal.
EXAMPLE
This example shows how to locate the log files used by dovecot(1).
doveadm log find
Looking for log files from /var/log
Debug: /var/log/dovecot.debug
Info: /var/log/mail.log
Warning: /var/log/mail.log
Error: /var/log/mail.log
Fatal: /var/log/mail.log
REPORTING BUGS
Report bugs, including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>. Information about reporting bugs is avail-
