Well, you can delete everything and copy afresh:
Code:
rm -rf /appabc2/*;cp -rp /appabc1/* /appabc2

or go by modified date, checksum or bit for bit compare of every file. Do you need to trim excess files in /appabc2/ ? New files need to be added, of course. Can there be new dirs? See man cpio pass option with updates only, which does a lot of this. The rsync command seems overkill for local files. Off the cuff = untested, files only, exact compare:
Code:
(
  cd /appabc1
  find . -type f
  cd /appabc2
  find . -type f
 ) | sort -u | while read f
do
 f="${f#./}"
 if [ ! -f "/appacb1/$f" ]
 then
  rm -f "/appabc2/$f"   # prune
  continue
 fi
 if [ -f /appabc2 -a "$(cmp "/appacb1/$f" "/appabc2/$f" 2>&1)" = "" ]
 then
  continue
 fi
 cp -p "/appacb1/$f" "/appabc2/$f"
done

raidctl and resync when reboot

I am using raidctl on a v440 disk and noticed it resyncs after every boot, which takes about 30 minutes because of the size of the partition. I am concerned with what happens during the resync if "writes" happen to the disk before it is complete? Any info would be helpful. Thanks (0 Replies)

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
