Hi Jim,


The grep works in Linux but not in Solaris. Sorry, forgot to mention, OS is SunOS <hostname> 5.11 11.3 sun4v sparc sun4v


Yeah, the code below works and files.tmp did has the list of files with their checksum, I only need to retain one of the files. Trying to work out how to sort the output AND retain just the lowest numbered file.



Code:
cd /path/to/logs

grep -l "CORRUPTION DETECTED" *.log  |
while read fname
do
   cksum $fname
done | sort -n -k1 > files.tmp
# files.tmp has a sorted list of files - by checksum




Code:
$: cat files.tmp
1237008222      10664   log.10
1237008222      10664   log.12
1237008222      10664   log.14
1237008222      10664   log.16
1237008222      10664   log.18
1237008222      10664   log.2
1237008222      10664   log.4
1237008222      10664   log.6
1237008222      10664   log.8
2296620157      10696   log.1
2296620157      10696   log.11
2296620157      10696   log.13
2296620157      10696   log.15
2296620157      10696   log.17
2296620157      10696   log.3
2296620157      10696   log.5
2296620157      10696   log.7
2296620157      10696   log.9


So from the list above, I will only want to retain log.1 and log.2, so kinda like group the output list above by checksum and retain the lowest number named file. Googling at the moment if there is an easier of deleting from the files.tmp list besides how am doing it below:


Code:
#!/bin/ksh
#

awk '{ print $1 }' files.tmp | sort | uniq > tmp.00

while read checksum
do
   grep "^$checksum" files.tmp | sort | sort -n -t. -k2 | awk 'NR>1 { print $3 }' | xargs rm
done < tmp.00


BTW, what is the code here below. I think there is something missing here, is oldfile supposedly the script that does the checksum and then I run the code below?



Code:
oldsum=0
oldfile
ls logfile* | 
while read sum size name
do
   if [  "$sum" -eq $oldsum ] ; then
      echo "$oldname and $name are duplicates"
      # put a rm command here after you see this work correctly for you
      # assuming you delete the second file name
      continue
   fi
   oldname=$name
   oldsum=$sum
done

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-
       able at: http://dovecot.org/bugreport.html
