Top Forums UNIX for Dummies Questions & Answers Rename file-name minus one? Post 302404863 by RacerX on Thursday 18th of March 2010 08:33:03 AM
Old 03-18-2010
It almost works after a bit of debugging: a missing semi-colon after s=$0, but it errors out because the path has underscores in it too! The updated code i am using in php:
Code:
$renamecmd = `ls $mydir/page_*.jpg | awk -F"[_.]" '{ s=$0; $0=$1"_"sprintf("%03d",int($2)-1)"."$3} {print "mv " s " " $0}' | sh`;

Results in the error:
Code:
mv: cannot move `/home/usr1/public_html/cards/my_programs/h083de63/NFLD/NFLD199007300730PM/pages/page_001.jpg' to `/home/usr1/public_-01.programs/h083de63/NFLD/NFLD199007300730PM/pages/page': No such file or directory

Anyway to fix this?

Solved the underscore in path problem by sending a change directory command before the solution posted by Franklin52. Hope it helps somebody else avoid wasting a whole work day trying to figure out how to rename ordered files:

Code:
$renamecmd = `cd $mydir; ls page_*.jpg | awk -F"[_.]" '{ s=$0; $0=$1"_"sprintf("%03d",int($2)-1)"."$3} {print "mv " s " " $0}' | sh`;

locale::codes::langext

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

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.
