Top Forums Shell Programming and Scripting awk to parse section of csv into array Post 303032147 by nezabudka on Tuesday 12th of March 2019 10:19:24 PM

Code:
s=$(awk '/^Sample_[0-9]/      {print $2}' file.csv)
echo $s

but it is not array. The array is like this
Code:
s=($(awk '/^Sample_[0-9]/      {print $2}' file.csv))
echo ${s[@]}

Code:
awk '
/^\[Data/               { f = 1 }
f && /^\[/              { f = 0 }
f && /^Sample_[0-9]/    { print $2 }' file.csv

I certainly don't know the complexity of your CSV file. But the algorithm that you want to implement looks like so in my opinion
Code:
awk -v k="Sample_Name" '
/^\[Data/               { f = 1
                          getline
                          for(i=1; i <= NF; i++) if (k == $i) break
                          next
                        }
f && /^\[/              { f = 0
                        }
f                       { print $i
                        } ' file.csv

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

NAME
Locale::Codes::LangVar - standard codes for language variation identification SYNOPSIS
use Locale::Codes::LangVar; $lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic' $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langvar_codes(); @names = all_langvar_names(); DESCRIPTION
The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, 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 variations. 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: $lvar = code2langvar('en','alpha-2'); $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2); The codesets currently supported are: alpha This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian. This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA". This is the default code set. ROUTINES
code2langvar ( CODE [,CODESET] ) langvar2code ( NAME [,CODESET] ) langvar_code2code ( CODE ,CODESET ,CODESET2 ) all_langvar_codes ( [CODESET] ) all_langvar_names ( [CODESET] ) Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] ) Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] ) Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME ) Locale::Codes::LangVar::delete_langvar_alias ( NAME ) Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
