1. one-liner: read first elements of a huge directory
At a client we have a networked disk with millions of files. I was trying to list the first few files to see what's going on.
ls -l | head takes ages, but here is a Perl one-liner to make it work:
perl -E 'opendir(my $dh, "/huge_dir"); my $c = 0; while (my $d = readdir($dh)) { say $d; exit if ++$c > 3 }'
In a different layout that could be put in a file
use feature 'say';
opendir(my $dh, "/huge_dir");
my $c = 0;
while (my $d = readdir($dh)) {
say $d;
exit if ++$c > 3
}

Deploying a containerized app gets easier everyday as cloud providers release new products. One of such products by AWS is AWS App Runner.
AWS App Runner is a fully managed container application service that lets you build, deploy, and run containerized web applications and API services without prior infrastructure or container experience.
Ever want to just deploy an app without the Kubernetes or complex networking overhead? Or have a couple of services to maintain without alot of configuratio…
