Please always state your problem clearly. By changing the requirement you are simply wasting the time of the member who tried to help you.

I would suggest using Associative Arrays for this requirement:
Code:
#!/bin/bash

typeset -A arr

while read line
do
        var="${line%%=*}"
        for key in ${line//,/ }
        do
                val="${key#${var}=}"
                val="${val%=*}"
                if [ ! -z arr["$var"] ]
                then
                        arr["$var"]="${arr["$var"]} $val"
                else
                        arr["$var"]="$val"
                fi
        done
done < file

for k in "${!arr[@]}"
do
        printf "%s %s\n" "$k" "${arr["$k"]}"
done

Input:
Code:
$ cat file
temp=/usr=25,/usr/lib=12
bin=12
etc=45
lib=12:6

Output:
Code:
$ ./script.bash
bin  12
etc  45
lib  12:6
temp  /usr /usr/lib

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
