perl function stat

The stat function in Perl is used to retrieve file or file system status information. It returns a list of values that contain information about the file, such as its size, ownership, permissions, and timestamps.

Here's an example of using the stat function:

my $file = 'example.txt';
my @file_info = stat($file);

print "File size: " . $file_info[7] . "\n";
print "Owner UID: " . $file_info[4] . "\n";
print "Last access time: " . $file_info[8] . "\n";

Output:

File size: 50
Owner UID: 501
Last access time: 1643861841

In this example, we have a file named example.txt. We use the stat function to retrieve the file status information and assign the results to an array @file_info.

We then print out some of the file status information using the array indices. $file_info[7] gives us the file size, $file_info[4] gives us the owner's user ID, and $file_info[8] gives us the last access time of the file.
