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.

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.

New deal July 21st, 2026. The US Mint regularly releases limited-edition coins to collectors. The coin sets are often limited to one per household, but end up with a market value greater than the initial cost. PFS Buyers Club is a website broker that recruits regular folks to buy their allotted coin set with a set markup amount, with the agreement that they will sell only to PFS Buyers Club. For example, you might pay $300 for a coin and they’ll agree to pay you $350 for it – a fixed profit of $50.

On Tuesday, July 21st at 12:00 pm Noon Eastern Time, there is a new guaranteed profit opportunity. A limited edition American Eagle 2026 One Ounce Silver Enhanced Uncirculated Coin will be released then, with a purchase limit of ten (10) per household.

PFS will pay you a fixed commission of $104.05 for 10 coins (must be exactly 10), on top of your cost for the set. The total paid is $1,800. The cost of each order of ten coins will be $1,690. After including the $5.95 shipping charge, each order’s total will be $1,695.95. If you subscribed to these or have already made three purchases with the Mint this year, you should get free shipping.

You’ll also earn credit card rewards on your ~$1,700 purchase (worth another ~$34 at 2% cash back), or also possibly satisfying the requirements for some $500+ value credit card bonuses. This makes the total net profit safely around $138.

Note that the eventual value of the set may exceed that elsewhere – you may see a higher bid on eBay, for example – but if you want to make that bet, don’t promise to sell to PFS Buyers Club. Just buy it on your own and try to sell it yourself. Keep in mind that eBay seller fees can be quite high (13.25%+ of the final selling price + PayPal fees), and you’ll be responsible for other costs like the proper shipping with adequate insurance. PFS Buyers Club will send you a free prepaid mailing label (including tracking and insurance) and pay you via eCheck, paper check, or PayPal. Even as an experienced eBay seller, I still prefer a low-stress experience when dealing with these types of valuables. You don’t have the risk of a price drop, or a random eBay user who claims never to have received your coin.

My past experience. I have used PFS successfully several times since 2021. Everything has gone smoothly each time and I have been paid my money in full without issue. The amount of communication was great and in fact better than expected; I was kept up-to-date every step of the way.

The total time commitment was the stop at the Fedex store to drop off the box with prepaid label. The eCheck option worked great – I printed the check out at home and deposited immediately via mobile app. PFS has a very solid reputation online. Their success has spawned many competitors, and some may offer you more money than PFS. I have nothing positive or negative to say about the competitors, as I have never used them. As always, I try to write based on my own personal experience. However, if this is your very first deal, I would consider PFS because they have the longest reputation and a time-tested process. I think it’s a good setup for beginners (well, those who are good at following directions) and folks who want minimal risk like myself.

If this interests you, you can sign up to join PFS Buyers Club here to see the details on the current offers (there may be another deal coming up soon on 7/16). Sometimes these deals fill up, so I would sign-up (it’s free) and opt-in sooner rather than later. You can still opt out of the deal until an hour prior to the coins going on sale. They will provide very detailed instructions. Follow them carefully, and it was pretty easy for me as a first-time buyer. If you use that link, I will receive a referral fee the first time you successfully sell your coin for a profit. Thanks for those that use it, and for those that already used it years ago! You’ll also be notified for future deals, some of which have very little upfront notice.

(p.s. I don’t write about coin deals often, the last one I wrote about was back in 2022 I think, this one just seemed to be a good mix of profit and spend. Some deals require a huge upfront purchase, and others the profit is under $100 and not worth my time.)
