How to fetch values from a line in a file to variables in UNIX?
Hi,

I need to assign values from a lines in a file into variables in unix, i am using Korn shell.

I tried the below script from posts but i am unable to fetch every value in a variable.

Code:
#! /usr/bin/ksh

#for file in test.txt; do
IFS=$'\|'
I=1
while read -a val
do
echo "val[${I}]=${val[${I}]}"
I=` expr ${I} + 1 `
done < fs_mail.txt
#done

but i am getting error.

Code:
test_script_2.ksh[7]: read: -a: unknown option
Usage: read [-ACprsv] [-d delim] [-u fd] [-t timeout] [-n nchar] [-N nchar] [var?prompt] [var ...]

I tried this it worked but my file is pipe | separated ,variable are not as i expected.

Code:
#!/usr/bin/ksh
I=1
for WORD in $(cat test.txt); do
WORDS[$I]=$WORD
echo "WORDS[$I]=$WORD"
I=$((I + 1))
done

File will look like

Code:
line1|111|22|33|44|55|aa|bb|cc
line2|dd|ee|ff|gg|ii|jj|kk|ll|mm|nn|oo|pp

Could anyone Please advise, how to achive.

Thanks,
Regards,
karthikram

locale::codes::langfam5.18

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

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.
