We all write programs to run on the terminal to do jobs that take time, like processing logs, sending out newsletter, etc. To know the progress of our task we print some messages to know our program is running well and doing its job. But wouldn't it be nice if we could add a...

When your script writes to a new file, you probably want it to create a new and unique name for the new file, one that doesn't conflict with any existing files, which would be overwritten. One way to create a new file name that's unique is to incorporate the process id and the time into the name....

There is a function ucwords() in PHP which capitalizes the first letter of each word.
<?
$str = "programming forums";
$str = ucwords($str);
// now $str = "Programming Forums"
?>
I have written a sub-routine in Perl, which gives the same functionality.

The normal idea is to have an hash table, iterate over the array and using the elements as keys.
Something like ::(
my @array = (1,5,3,7,9,1,4,5,7,6,7);
my %hash;
foreach my $element (@array) {
$hash{$element}++
}
