my @employee = ( [29243, 'john', 'John doe'],

);
Is there any builtin function in perl to sort the above array based on uid,
username or fulname?
There is a built-in function to sort a list, yes. But the mechanism by
which to sort the list is, in this case, up to you to provide. This
works:
my @sorted = sort {
$a->[0] <=> $b->[0]
} @employees;
In the sort() block, $a and $b are two elements of the list being
compared. Since the elements are array references, and their first
element is their UID, I've used $a->[0] <=> $b->[0] to compare those two
values. See the documentation for 'sort' (perldoc -f sort) for more
details.
