Hi,
Code:
find . -name '*.log.[0-9][0-9][0-9]' |    # get a the names of all the hosts
sort -t. -k1.2,1n -k2 |                   # sort this using a "." as a field separator; sort
                                          # numerically with the 2nd character to the last
                                          # character of the first field and for the second
                                          # key use a regular sort from filed 2 onwards.
while read f
do
  printf "%s " "$f"
  tail -1 "$f"
done

To get rid of the ./ and the timestamp, aa quick fix would be:
Code:
...
do
   printf "%s" "${f##*/}"
   tail -1 "$f" | awk '{$1=x}1'
done

Or a bit more efficiently if the file name do not contain spaces, perhaps
Code:
...
do
   printf "%s " "${f##*/}"
   tail -1 "$f" 
done | awk '{$2=x}1'

X25 Address - A challenge...

Okay - I've been searching near and far for the answer to this seemly simple question..... how do I find the X25 address for a server. Is there some sort of dump or ping or even a config which would tell me the address. I can find nothing on the web and my colleagues can't help either. (1 Reply)

locale::codes::langext

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. 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 = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
