CPU & Memory Expected output

Expected output:

In a text file:

Parent1
child1
child2

parent2
child21
child22
child23

parent3

child31
child32
....

***************************************

In the file 'a' and 'b' are the identifiers for the parent and children.

Thanks to you.

I thought of doing something like:

step 1: Grep for parents and then after I get the list of parents {may be in an array}

step 2: I can grep for children with a condition which checks if I hit the first parent from the previously obtained list. When I hit the first parent then save the child list to a text file with the parent name on it.

step 3: Again proceed for the next ones by keeping every thing in a for loop and update the text file every time.


If this algorithm sounds good then the point I am stuck with is step 2.

can you help me out there/ or with any other alternative way.

NAME
Locale::Msgcat - Perl extension for blah blah blah SYNOPSIS
use Locale::Msgcat; $cat = new Locale::Msgcat; $rc = $cat->catopen(name, oflag); $msg = $cat->catgets(set_number, message_number, string); $rc = $cat->catclose(); DESCRIPTION
The Locale::Msgcat module allows access to the message catalog functions which are available on some systems. A new Locale::Msgcat object must first be created for each catalog which has to be open at a given time. The catopen operation opens the catalog whose name is given as argument. The oflag can be either 0 or NL_CAT_LOCALE (usually 1) which is the recommended value. The catgets message retrieves message_number for the set_number message set, and if not found returns string. The catclose function should be used when access to a catalog is not needed anymore. EXAMPLES
use Locale::Msgcat; $cat = new Locale::Msgcat; unless ($cat->catopen("whois.cat", 1)) { print STDERR "Can't open whois catalog. "; exit(1); } printf "First message, first set : %s ", $cat->catgets(1, 1, "not found"); unless ($cat->catclose()) { print STDERR "Can't close whois catalog. "; exit(1); } The above example would print the first message from the first message set found in the whois catalog, or if not found it would print "not found". AUTHOR
