A Bash Script to Read All Command Line Arguments into an Array: Simplify Argument Handling

nixCraft - 18 hours 18 min ago
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.

How to Pin Versions in Yum or Dnf for RHEL or CentOS Linux

nixCraft - 18 hours 18 min ago
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.

How to add cron job entry for acme.sh

nixCraft - 18 hours 18 min ago
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!

Seven Years Later, Airbus is Still Trying To Kick Its Microsoft Habit

Slashdot.org - 19 hours 23 min ago
Breaking free from Microsoft is harder than it looks. Airbus began migrating its 100,000-plus workforce from Office to Google Workspace more than seven years ago and it still hasn't completed the switch. The Register: As we exclusively revealed in March 2018, the aerospace giant told 130,000 employees it was ditching Microsoft's productivity tools for Google's cloud-based alternatives. Then-CEO Tom Enders predicted migration would finish in 18 months, a timeline that, in hindsight, was "extremely ambitious," according to Catherine Jestin, Airbus's executive vice president of digital. Today, more than two-thirds of Airbus's 150,000 employees have fully transitioned, but significant pockets continue to use Microsoft in parallel. Finance, for example, still relies on Excel because Google Sheets can't handle the necessary file sizes, as some spreadsheets involve 20 million cells. "Some of the limitations was just the number of cells that you could have in one single file. We'll definitely start to remove some of the work," Jestin told The Register.

Canada Rolls Back Climate Rules To Boost Investments

Slashdot.org - 21 hours 53 min ago
Canada's Prime Minister Mark Carney has signed an agreement with Alberta's premier that will roll back certain climate rules to spur investment in energy production, while encouraging construction of a new oil pipeline to the West Coast. From a report: Under the agreement, which was signed on Thursday, the federal government will scrap a planned emissions cap on the oil and gas sector and drop rules on clean electricity in exchange for a commitment by Canada's top oil-producing province to strengthen industrial carbon pricing and support a carbon capture-and-storage project. The deal, which was hailed by the country's oil industry but panned by environmentalists, signaled a shift in Canada's energy policy in favour of fossil fuel development and is already creating tensions within Carney's minority government. Steven Guilbeault, who served as environment minister under Carney's predecessor Justin Trudeau, said he was quitting the cabinet over concerns that Canada's climate plan was being dismantled.

US Patent Office Issues New Guidelines For AI-Assisted Inventions

Slashdot.org - Thu, 11/27/2025 - 21:30
The U.S. Patent and Trademark Office has issued new guidelines outlining when inventions created with the help of AI can be patented. From a report: USPTO Director John Squires said on Wednesday in a notice set to be published Friday, that the office considers generative AI systems to be "analogous to laboratory equipment, computer software, research databases, or any other tool that assists in the inventive process." "They may provide services and generate ideas, but they remain tools used by the human inventor who conceived the claimed invention," the office said. "When one natural person is involved in creating an invention with the assistance of AI, the inquiry is whether that person conceived the invention under the traditional conception standard." The office reiterated its guidance from last year that AI itself cannot be considered an inventor under U.S. patent law. However, it rejected the approach taken by the PTO during former President Joe Biden's administration for deciding when AI-assisted inventions are patentable, which relied on a standard normally used to determine when multiple people can qualify as joint inventors.
