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.

Here's a quick tip for vim users. You can perform find and replace operations within a visual selection in Vim for text or code block. Visual selection for finding and replacing text in Vim allows developers and Linux/Unix users precise and efficient text editing. It's handy when you want to change specific portions of text or code blocks within a larger file without affecting other occurrences. This method required to minimizing manual search and reducing the risk of unintended code or text modifications. Let us see how to find and replace in Vim visual mode selection.

Bash is a command language interpreter compatible with sh. It can execute commands read from a file or keyboard. On Debian Linux, bash-completion is a set of shell functions that uses Bash's programmable completion feature.

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!

You can find the timezone in Linux using the command line. The easiest way to do this is to type the "timedatectl" command and look for the "timezone" line when using modern Linux distros with systemd.

Researchers and moderators are increasingly concerned that ChatGPT-style language is bleeding into everyday speech and writing. The topic has been explored in the past but "two new, more anecdotal reports, suggest that our chatbot dialect isn't just something that can be found through close analysis of data," reports Gizmodo. "It might be an obvious, every day fact of life now." Slashdot reader joshuark shares an excerpt from the report: Over on Reddit, according to a new Wired story by Kat Tenbarge, moderators of certain subreddits are complaining about AI posts ruining their online communities. It's not new to observe that AI-armed spammers post low-value engagement bait on social media, but these are spaces like r/AmItheAsshole, r/AmIOverreacting, and r/AmITheDevil, where visitors crave the scintillation or outright titillation of bona fide human misbehavior. If, behind the scenes, there's not really a grieving college student having her tuition cut off for randomly flying off the handle at her stepmom, there's no real fun to be had. The mods in the Wired story explain how they detect AI content, and unfortunately their methods boil down to "It's vibes." But one novel struggle in the war against slop, the mods say, is that not only are human-written posts sometimes rewritten by AI, but mods are concerned that humans are now writing like AI. Humans are becoming flesh and blood AI-text generators, muddying the waters of AI "detection" to the point of total opacity. As "Cassie" an r/AmItheAsshole moderator who only gave Wired her first name put it, "AI is trained off people, and people copy what they see other people doing." In other words, Cassie said, "People become more like AI, and AI becomes more like people." Meanwhile, essayist Sam Kriss just explored the weird way chatbots "write" for the latest issue of the New York Times Magazine, and he discovered along the way that humans have accidentally taken cues from that weirdness. After parsing chatbots' strange tics and tendencies -- such as overusing the word "delve" most likely because it's in a disproportional number of texts from Nigeria, where that word is popular -- Kriss refers to a previously reported trend from over the summer. Members of the U.K. Parliament were accused of using ChatGPT to write their speeches. The thinking goes that ChatGPT-written speeches contained the phrase "I rise to speak," an American phrase, used by American legislators. But Kriss notes that it's not just showing up from time to time. It's being used with downright breathtaking frequency. "On a single day this June, it happened 26 times," he notes. While 26 different MPs using ChatGPT to write speeches is not some scientific impossibility, it's more likely an example of chatbots, "smuggling cultural practices into places they don't belong," to quote Kriss again. So when Kriss points out that when Starbucks locations were closing in September, and signs posted on the doors contained tortured sentences like, "It's your coffeehouse, a place woven into your daily rhythm, where memories were made, and where meaningful connections with our partners grew over the years," one can't state with certainty that this is AI-generated text (although let's be honest: it probably is).

Anthropic is bringing Claude Code directly into Slack, letting developers spin up coding sessions from chat threads and automate workflows without leaving the app. TechCrunch reports: Previously, developers could only get lightweight coding help via Claude in Slack -- like writing snippets, debugging, and explanations. Now they can tag @Claude to spin up a complete coding session using Slack context like bug reports or feature requests. Claude analyzes recent messages to determine the right repository, posts progress updates in threads, and shares links to review work and open pull requests. The move reflects a broader industry shift: AI coding assistants are migrating from IDEs (integrated development environment, where software development happens) into collaboration tools where teams already work. [...] While Anthropic has not yet confirmed when it would make a broader rollout available, the timing is strategic. The AI coding market is getting more competitive, and differentiation is starting to depend more on integration depth and distribution than model capability alone.
