If you are writing a Bash shell script, you should read command-line arguments into an array for some time. This allows us to process any number of arguments provided when the script is run. This makes the script adaptable to different use cases. Instead of dealing with fixed variables like $1, $2, $3, etc., you can work with any number of arguments more dynamically using bash for loop or bash while loop, depending upon your needs. Arrays make it simple to loop through each argument and perform operations on them, whether basic printing or complex processing. Bash provides a mapfile (readarray command) internal built-in command to read lines from a file into an array variable. Let us see how to use mapfile to read all command line arguments into an array.

CentOS, RHEL (Red Hat Enterprise Linux), Fedora and other clones of RHEL, such as Oracle, Alma, and Rocky, offer support for version pinning. This feature allows developers and system administrators to lock a particular package to a specific version, preventing it from being automatically updated by yum or dnf commands. Sometimes, it is necessary to protect packages from being updated to newer versions to avoid incompatibility issues with your applications. For example, you can lock down PHP version 8.3.6 and avoid using updated PHP version 8.4. Let us see how to lock a package to a specific version, only exclude a package from yum update or dnf update on a CentOS, RHEL, Fedora, and friends.

Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

Microsoft has patched a high-severity vulnerability in Windows 11's Notepad that allowed attackers to silently execute local or remote programs when a user clicked a specially crafted Markdown link, all without triggering any Windows security warning. The flaw, tracked as CVE-2026-20841 and fixed in the February 2026 Patch Tuesday update, stemmed from Notepad's relatively new Markdown support -- a feature Microsoft added after discontinuing WordPad and rewriting Notepad to serve as both a plain text and rich text editor. An attacker only needed to create a Markdown file containing file:// links pointing to executables or special URIs like ms-appinstaller://, and a Ctrl+click in Markdown mode would launch them. Microsoft's fix now displays a warning dialog for any link that doesn't use http:// or https://, though the company did not explain why it chose a prompt over blocking non-standard links entirely. Notepad updates automatically through the Microsoft Store.

Linux 7.0 MM Changes Bring Some Very Nice Performance Optimizations  Phoronix

An anonymous reader shares a report: Just weeks after a dramatic purge of China's top general, the CIA is moving to capitalize on any resulting discord with a new public video targeting potential informants in the Chinese military. The U.S. spy agency on Thursday rolled out the video depicting a disillusioned mid-level Chinese military officer, in the latest U.S. step in a campaign to ramp up human intelligence gathering on Washington's strategic rival. It follows a similar effort last May that focused on fictional figures within China's ruling Communist Party that provided detailed Chinese-language instructions on how to securely contact U.S. intelligence. CIA Director John Ratcliffe said in a statement that the agency's videos had reached many Chinese citizens and that it would continue offering Chinese government officials an "opportunity to work toward a brighter future together."

IBM said it will triple entry-level hiring in the US in 2026, even as AI appears to be weighing on broader demand for early-career workers. From a report: While the company declined to disclose specific hiring figures, it said the expansion will be "across the board," affecting a wide range of departments. "And yes, it's for all these jobs that we're being told AI can do," said Nickle LaMoreaux, IBM's chief human resources officer, speaking at a conference this week in New York. LaMoreaux said she overhauled entry-level job descriptions for software developers and other roles to make the case internally for the recruitment push. "The entry-level jobs that you had two to three years ago, AI can do most of them," she said at Charter's Leading With AI Summit. "So, if you're going to convince your business leaders that you need to make this investment, then you need to be able to show the real value these individuals can bring now. And that has to be through totally different jobs."

WP Engine's third amended complaint against Automattic and WordPress co-founder Matt Mullenweg alleges that Mullenweg had plans to impose royalty fees on 10 hosting companies beyond WP Engine for their use of the WordPress trademark. The amended filing, based on previously sealed information uncovered during discovery, also claims Mullenweg emailed a Stripe executive to pressure the payment processor into canceling WP Engine's contract after WP Engine sued Automattic in October 2024. Newfold, the parent company of Bluehost and HostGator, is already paying Automattic for trademark use, according to the complaint, and Automattic is in conversations with other hosts. The filing challenges the 8% royalty rate as arbitrary, citing Mullenweg's comments at TechCrunch Disrupt 2024 where he said the figure was based on what WP Engine "could afford to pay." Internal Automattic correspondence cited in the complaint includes Mullenweg describing his approach to WP Engine as "nuclear war" and warning that if the hosting company didn't comply, he would start stealing its customers.

An anonymous reader shares a report: Palo Alto Networks opted not to tie China to a global cyberespionage campaign the firm exposed last week over concerns that the cybersecurity company or its clients could face retaliation from Beijing, according to two people familiar with the matter. The sources said that Palo Alto's findings that China was tied to the sprawling hacking spree were dialed back following last month's news, first reported by Reuters, that Palo Alto was one of about 15 U.S. and Israeli cybersecurity companies whose software had been banned by Chinese authorities on national security grounds. A draft version of the report by Palo Alto's Unit 42, the company's threat intelligence arm, said that the prolific hackers -- dubbed "TGR-STA-1030" in a report published on Thursday of last week -- were connected to Beijing, the two people said. The finished report instead described the hacking group more vaguely as a "state-aligned group that operates out of Asia." Attributing sophisticated hacks is notoriously difficult and debates over how best to assign blame for digital intrusions are common among cybersecurity researchers.
