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.

locale::msgcat
Msgcat(3pm) User Contributed Perl Documentation Msgcat(3pm)
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".
