My task is, to write a "one-line" command, which must use ls and awk.
Task: Write a command-line, which should rename all files in dir from form "value1.dok" to "value2.doc". And value2=value1+1.
For example:
Code:
ls | awk -F: '{print "mv "$0" "$1+1".doc"}' | sh
But this doesn't work with a filename with characters. Therefore i tested this:
Code:
ls | awk -F: '{print "mv "$0" value"substr($1 ,6)+1".doc"}' | sh
This worked, but my taskprogram say "wrong" and want see a other command (perhaps with different string?)
So i tested it with regular expressions, but my console say always "syntax error":
Code:
ls | awk -F: '{print "mv "$0" "${1%[!0-9]*}""${1%[0-9]*}+1".doc"}' | sh
I havent any idea how i could it bring to work in one line...
Can someone perhaps help me?
And sorry for my very bad english
Is it possible to combine a regular expression with a aritmetical expression? For example, taking a 8-numbers caracter sequece and casting each output of a grep, comparing to a constant.

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
code2langfam ( CODE [,CODESET] )
langfam2code ( NAME [,CODESET] )
langfam_code2code ( CODE ,CODESET ,CODESET2 )
all_langfam_codes ( [CODESET] )
all_langfam_names ( [CODESET] )
Locale::Codes::LangFam::rename_langfam ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangFam::add_langfam ( CODE ,NAME [,CODESET] )
Locale::Codes::LangFam::delete_langfam ( CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_alias ( NAME ,NEW_NAME )
Locale::Codes::LangFam::delete_langfam_alias ( NAME )
Locale::Codes::LangFam::rename_langfam_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::delete_langfam_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
