awk uses associative arrays, before you ask.
Hello,

I used the code you provided as follows. In my shell script I have a line that calls the awk script:

awk -f processing.awk names.tmp

In processing.awk I modified your code as follows:
{ arr[$1]++; continue }
END { for (i in arr) {print i, arr[i] }

When the script runs it says:
awk: processing.awk:3: { arr[$1]++; continue }
END { for (i in arr) {print i, arr[i] }

awk: processing.awk:3: ^ syntax error

Can you help me troubleshoot the problem please?

get_defined_functions - Returns an array of all defined functions

SYNOPSIS
array get_defined_functions (void ) DESCRIPTION
Gets an array of all defined functions. RETURN VALUES
Returns a multidimensional array containing a list of all defined functions, both built-in (internal) and user-defined. The internal func- tions will be accessible via $arr["internal"], and the user defined ones using $arr["user"] (see example below). EXAMPLES
Example #1 get_defined_functions(3) example <?php function myrow($id, $data) { return "<tr><th>$id</th><td>$data</td></tr> "; } $arr = get_defined_functions(); print_r($arr); ?> The above example will output something similar to: Array ( [internal] => Array ( [0] => zend_version [1] => func_num_args [2] => func_get_arg [3] => func_get_args [4] => strlen [5] => strcmp [6] => strncmp ... [750] => bcscale [751] => bccomp ) [user] => Array ( [0] => myrow ) ) SEE ALSO
