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!

Flipper One Brings Linux Computing Straight Into Your Pocket  TechEBlog -

Updated with new limited-time offers. Hilton Hotels and American Express have co-branded credit cards with special perks for Hilton customers. Each person can typically only get one welcome offer, per card in your entire lifetime, so it’s best to apply during a temporary bump-up and/or limited-time offer.

What are Hilton Honor points worth? The best value is from booking free hotel nights or using their “Points & Money” option where you pay with a combination of Hilton points and cash. Hilton has some really nice properties, but the value varies from hotel to hotel. I just ran a search and for the same 60,000 Hilton points, I could book rooms that cost $320 or $532 cash. I’ve seen some valuations around 0.6 cents per point, which I think is fair on average, but I would be more conservative at 0.5 cents a point. That would make 150,000 points = $750 value and 100,000 points = $500 value towards Hilton hotel stays.

The good part of Hilton points is that they have so many different hotel brands, from business-class DoubleTree to luxury Waldorf Astoria. Hilton also lets you transfer and pool points with other with other family or household members. As long as you are able to keep them active (once every 12 months), I do like to keep some around. These credit cards are handy for creating activity.

Free Night Award details. When it is offered (not all the time), the Free Night Award is valid for a one-night standard room at eligible Hilton properties, and also covers resort fees and taxes. There are many great and valuable options to redeem, but importantly read about the property exclusions here. Here are the full terms. To redeem the Free Night Reward, you must call 1-800-446-6677 (1-800-HHONORS). It’s quite easy and I’ve found the agents to be very helpful if you want to combine multiple certificates, combine a paid stay and a Free Night Award, etc. Free Night Rewards will expire 12 months from date of issuance.

I’ve used this Free Night Award at the Grand Wailea in Maui, and that standard room would have cost 110,000 Hilton Points otherwise. Other fancy possibilities include Conrad New York, Conrad London, Waldorf Astoria Park City, and Waldorf Astoria Beverly Hills.

Bottom line. Hilton American Express cards offer regular Hilton customers a good opportunity to earn additional points towards free Hilton hotel stays as well as additional perks like status upgrades. The best time to apply for a Hilton co-branded American Express card is during a limited-time increase to their welcome offers. This is because American Express has changed their standard policy to only allow each person to get a welcome offer once per card.
