Using echo in AWK
Hello,
I have written the script below to extract specific data from a text file and then use the data extracted as parameters for another shell script call 'loto_tsim'.
Everytime I run my script it complains about the 'echo' line. Am I missing something? I have spent hours and still cannot solve this, can anyone help?
#!/bin/sh
awk 'NR==1 {n = split($3, array, "-");
lotoE="1\n 20\n 0\n 0\n 1\n 1\n 7\n 0\n array[1]\n array[2]\n array[3]\n array[4]\n array[5]\n array[6]\n 1\n 1\n 0\n 0\n 0\n N\n 1\n 100\n"
echo ${lotoE} | $LOTO/bin/loto_tsim > /dev/null 2>&1
}' LottWagers2.txt
----------------------THIS IS THE ERROR------------------------------
Syntax Error The source line is 6.
The error context is
echo >>> ${ <<<
awk: 0602-502 The statement cannot be correctly parsed. The source line is 6.

Stumped with the formatting of the awk output when used with variables, e.g.:
awk -F, 'BEGIN {OFS=","} print {$2,$3,$4}' $infile1
produces the desired output (with rows), but when echoing the variable below, the output is one continuous line

forward_static_call_array
FORWARD_STATIC_CALL_ARRAY(3) 1 FORWARD_STATIC_CALL_ARRAY(3)
forward_static_call_array - Call a static method and pass the arguments as array
SYNOPSIS
mixed forward_static_call_array (callable $function, array $parameters)
DESCRIPTION
Calls a user defined function or method given by the $function parameter. This function must be called within a method context, it can't
be used outside a class. It uses the late static binding. All arguments of the forwarded method are passed as values, and as an array, sim-
ilarly to call_user_func_array(3).
PARAMETERS
o $function
- The function or method to be called. This parameter may be an array, with the name of the class, and the method, or a string,
with a function name.
o $parameter
- One parameter, gathering all the method parameter in one array.
Note
Note that the parameters for forward_static_call_array(3) are not passed by reference.
RETURN VALUES
Returns the function result, or FALSE on error.
EXAMPLES
Example #1
forward_static_call_array(3) example
<?php
class A
{
const NAME = 'A';
public static function test() {
$args = func_get_args();
echo static::NAME, " ".join(',', $args)."
";
}
}
class B extends A
{
const NAME = 'B';
public static function test() {
echo self::NAME, "
";
forward_static_call_array(array('A', 'test'), array('more', 'args'));
forward_static_call_array( 'test', array('other', 'args'));
}
}
B::test('foo');
function test() {
$args = func_get_args();
echo "C ".join(',', $args)."
";
}
?>
The above example will output:
B
B more,args
C other,args
