IF you had mentioned your OS I could be sure of a better answer -
have you tried grep?
Code:
grep -A 10 -B 10  "CORRUPTION DETECTED" logfilename.log

is one way to it with many, but not all, OSes.

If files are duplicated and assuming you mean what is inside the file is the same then try a cksum

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

try:
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

Get this working for you , then you can delete identical files.

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
