If the above condition satisfies it should check whether field 1 datatype and length(numeric(9)) are same or not and also whether it is null. If not var1 = "101" and var2 desc "Missing/wrong field1", field 2 datatype and length(char(9)) are same or not also for null. if not then var1 ="102" var2 "Missing/wrong field2" and so on. Any help would be appreciated.
Here is the code:
If it's code, please put it inside [CODE] tags so that it is properly formatted.

#!/bin/ksh
eval $(awk 'BEGIN { IFS = "\t" }
What is the ouput of the awk script that you expect to eval?
In order to use eval, you need to output valid shell code.
Quote:
NR>=3 {print $1}
!/\t/ ## check whether lines contain tab else var1="105" and var2="No Tabs"
{
if ( length($1) == 0 || $1 !~ /[^0-9]/ ) ## check for null and numeric value and length(9)
You haven't checked that the length is 9. You have checked that it is not empty and that it doesn't contain any numbers.
That is not awk syntax.
Quote:
var1="101"
var2="Missing or wrong First Field"
elif ( length($2) == 0 || $2 !~ /[a-zA-Z]/ ) ## check for null and char value and length(9)
There is no 'then', 'elif', or 'fi' keyword in awk.
You still haven't (even after the syntax is fixed) checked that the length is 9. You have checked that it is not empty and that it doesn't contain any letters.
Quote:
then
var1="102"
var2="Missing or Wrong Second Field"
fi
}
}' $1)
echo "$var1"
echo "$var2"
I suggest that you start with the code I posted, and tell us what it lacks. (Reply directly to that post, quoting relevant segments.)

LEARN ABOUT PHP
var_export
VAR_EXPORT(3) 1 VAR_EXPORT(3)
var_export - Outputs or returns a parsable string representation of a variable
SYNOPSIS
mixed var_export (mixed $expression, [bool $return = false])
DESCRIPTION
var_export(3) gets structured information about the given variable. It is similar to var_dump(3) with one exception: the returned represen-
tation is valid PHP code.
PARAMETERS
o $expression
- The variable you want to export.
o $return
- If used and set to TRUE, var_export(3) will return the variable representation instead of outputting it.
RETURN VALUES
Returns the variable representation when the $return parameter is used and evaluates to TRUE. Otherwise, this function will return NULL.
NOTES
Note
When the $return parameter is used, this function uses internal output buffering so it cannot be used inside an ob_start(3) callback
function.
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.1.0 | |
| | |
| | Possibility to export classes and arrays con- |
| | taining classes using the __set_state() magic |
| | method. |
| | |
+--------+---------------------------------------------------+
EXAMPLES
Example #1
var_export(3) Examples
<?php
$a = array (1, 2, array ("a", "b", "c"));
var_export($a);
?>
The above example will output:
array (
0 => 1,
1 => 2,
2 =>
array (
0 => 'a',
1 => 'b',
2 => 'c',
),
)
<?php
$b = 3.1;
$v = var_export($b, true);
echo $v;
?>
The above example will output:
3.1
Example #2
Exporting classes since PHP 5.1.0
<?php
class A { public $var; }
$a = new A;
$a->var = 5;
var_export($a);
?>
The above example will output:
A::__set_state(array(
'var' => 5,
))
Example #3
Using __set_state() (since PHP 5.1.0)
<?php
class A
{
public $var1;
public $var2;
public static function __set_state($an_array)
{
$obj = new A;
$obj->var1 = $an_array['var1'];
$obj->var2 = $an_array['var2'];
return $obj;
}
}
$a = new A;
$a->var1 = 5;
$a->var2 = 'foo';
eval('$b = ' . var_export($a, true) . ';'); // $b = A::__set_state(array(
// 'var1' => 5,
// 'var2' => 'foo',
// ));
var_dump($b);
?>
The above example will output:
object(A)#2 (2) {
["var1"]=>
int(5)
["var2"]=>
string(3) "foo"
}
NOTES
Note
Variables of type resource couldn't be exported by this function.
Note
var_export(3) does not handle circular references as it would be close to impossible to generate parsable PHP code for that. If you
want to do something with the full representation of an array or object, use serialize(3).
Warning
When var_export(3) exports objects, the leading backslash is not included in the class name of namespaced classes for maximum com-
patibility.

print_r(3), serialize(3), var_dump(3).
