awk is used to filter and manipulate output from other programs and functions. awk works on programs that contain rules comprised of patterns and actions. The action awk takes is executed on the text that matches the pattern. Patterns are enclosed in curly braces ({}). Together, a pattern and an action form a rule. The entire awk program is enclosed in single quotes (').
The sed command is a bit like chess: it takes an hour to learn the basics and a lifetime to master them (or, at least a lot of practice). We'll show you a selection of opening gambits in each of the main categories of sed functionality.
sed is a stream editor that works on piped input or files of text. It doesn't have an interactive text editor interface, however. Rather, you provide instructions for it to follow as it works through the text. This all works in Bash and other command-line shells.

California's high-speed rail project officially began in 2008, although it was initiated on paper earlier. The whole system was initially planned to comprise 776 miles, with a completion date set for 2020. To date, none of the proposed rail network is operational. By way of comparison, the Transcontinental Railroad is 1,911 miles long, cutting through the Rockies and Sierra Nevada, and it was completed in 2,314 days, despite the Civil War and Indian raids. An [Irish track-laying crew laid 10 miles, 1,320 feet of track on a single day](https://en.wikipedia.org/wiki/Tracklaying_race_of_1869#Ten_Miles_of_Track,_Laid_in_One_Day:~:text=new%2520record%2520with-,10%25C2%25A0miles,-1%252C320%25C2%25A0feet%2520(16.496), while California has managed to lay 1,600 feet in nine years. //
The ballyhooed three-hour trip from LA to San Francisco only works if there are no stops. Once you add stops, the time starts to increase. There is no universe in which this rail line would not require large-scale government subsidies because the daily passenger demand just isn't there. At best, this is a sinecure for politically connected construction and consulting firms. At worst, it is outright theft. If California's voters are willing to foot the bill, they should be allowed to do so. The rest of us should be allowed to opt out, and thanks to Secretary Duffy, we have.
Fox News reported Wednesday that the Trump administration found every step of the streamlining and reorganization process to be difficult. Even something as simple as getting a list of the people who actually worked for the State Department turned out to require major effort. “It took us three months,” recounted one Trump State Department official, “to get a list of the people that actually work in the building.”
That’s your taxpayer dollars at work. “They couldn't tell you how many people worked here. It’s sort of scary as a taxpayer and as a public servant to think that we don’t even know how many employees we have. This is a national security agency, you know. Who are these people?” Yeah, good point. Not only were unknown amounts of money being wasted, but the State Department could have been the place of employ of any number of people whose loyalties lay elsewhere, or who were even at place in Foggy Bottom in order to gather information for hostile entities.
Inconceivable? If only it were.
Bureaucracy: The Real Engine Behind This Train
This isn’t just about a failed transit system. It’s about the broader addiction to government grandeur, the idea that massive spending equals progress, even when the results amount to a pile of gravel and invoices.
California’s rail saga should be taught in every high school civics class as a master class in government arrogance. The state formed committees to oversee subcommittees that evaluated contracts for lines that didn’t exist. Meanwhile, the actual train remains stuck in concept art and artist renderings. It’s easier to draw the train than to build it. //
The Private Sector Could've Built the Rails and Painted the Train Twice
Imagine if a private consortium had been handed $11 billion and told to build a rail line from L.A. to San Francisco. Given the right contractor, it would have been completed by now, including terminals, security, solar roofing, and possibly even a profit margin, potentially while under budget.

On March 24, 2025, God called FBM Missionary Rich Marshall home to heaven. Rich and Anna were in Mali wrapping up 40 years of faithful service to Christ. Just ten days later, on April 3, they had plans to leave Mali and retire to the US. Instead, God said, “Well done, thou good and faithful servant” to Rich and brought his time on earth to a close. Today, we would like to share some of Rich Marshall’s story with you and also bring you an update on what God continues to do in Mali.
Rich was born in 1955 in Timbuktu, Mali to missionaries Frank and Eleanor Marshall. His birth was not a worldwide headline. However, the impact of his birth is impossible to put into words.
In 1977, Rich married Anna and they began their life together. They spent several years in the US attending college and getting additional training. In 1982, they started raising support to return to Mali as missionaries. After a few years of support raising and language school, Rich and Anna returned to Timbuktu in 1985.
Upon returning to Timbuktu, Rich’s mindset was, “We’re here to share the Gospel!”

Ask and it will be given to you. . . . How much more will your Father in heaven give good gifts to those who ask him! —Matthew 7:7, 11. //
Notion your mind with the idea that God is there. If once the mind is notioned along that line, then when you are in difficulties it is as easy as breathing to remember — Why, my Father knows all about it! It is not an effort, it comes naturally when perplexities press. Before, you used to go to this person and that, but now the notion of the Divine control is forming so powerfully in you that you go to God about it. Jesus is laying down the rules of conduct for those who have His Spirit, and it works on this principle — God is my Father, He loves me, I shall never think of anything He will forget, why should I worry?

A pool is a collection of vdevs. Vdevs can be any of the following (and more, but we’re keeping this relatively simple):
single disks (think RAID0)
redundant vdevs (aka mirrors – think RAID1)
parity vdevs (aka stripes – think RAID5/RAID6/RAID7, aka single, dual, and triple parity stripes)
The pool itself will distribute writes among the vdevs inside it on a relatively even basis. //
striped (RAIDZ) vdevs aren’t supposed to be “as big as you can possibly make them.” Experts are cagey about actually giving concrete recommendations about stripe width (the number of devices in a striped vdev), but they invariably recommend making them “not too wide.” If you consider yourself an expert, make your own expert decision about this. If you don’t consider yourself an expert, and you want more concrete general rule-of-thumb advice: no more than eight disks per vdev. //
According to Dell, “Raid 5 for all business critical data on any drive type [is] no longer best practice.”
RAIDZ2 and RAIDZ3 try to address this nightmare scenario by expanding to dual and triple parity, respectively. This means that a RAIDZ2 vdev can survive two drive failures, and a RAIDZ3 vdev can survive three. Problem solved, right? Well, problem mitigated – but the degraded performance and resilver time is even worse than a RAIDZ1, because the parity calculations are considerably gnarlier. And it gets worse the wider your stripe (number of disks in the vdev). //
When a disk fails in a mirror vdev, your pool is minimally impacted – nothing needs to be rebuilt from parity, you just have one less device to distribute reads from. When you replace and resilver a disk in a mirror vdev, your pool is again minimally impacted – you’re doing simple reads from the remaining member of the vdev, and simple writes to the new member of the vdev. In no case are you re-writing entire stripes, all other vdevs in the pool are completely unaffected, etc. Mirror vdev resilvering goes really quickly, with very little impact on the performance of the pool. Resilience to multiple failure is very strong, though requires some calculation – your chance of surviving a disk failure is 1-(f/(n-f)), where f is the number of disks already failed, and n is the number of disks in the full pool. In an eight disk pool, this means 100% survival of the first disk failure, 85.7% survival of a second disk failure, 66.7% survival of a third disk failure. This assumes two disk vdevs, of course – three disk mirrors are even more resilient.
But wait, why would I want to trade guaranteed two disk failure in RAIDZ2 with only 85.7% survival of two disk failure in a pool of mirrors? Because of the drastically shorter time to resilver, and drastically lower load placed on the pool while doing so. The only disk more heavily loaded than usual during a mirror vdev resilvering is the other disk in the vdev – which might sound bad, but remember that it’s no more heavily loaded than it would’ve been as a RAIDZ member. //
Too many words, mister sysadmin. What’s all this boil down to?
- don’t be greedy. 50% storage efficiency is plenty.
for a given number of disks, a pool of mirrors will significantly outperform a RAIDZ stripe. - a degraded pool of mirrors will severely outperform a degraded RAIDZ stripe.
- a degraded pool of mirrors will rebuild tremendously faster than a degraded RAIDZ stripe.
- a pool of mirrors is easier to manage, maintain, live with, and upgrade than a RAIDZ stripe.
- BACK. UP. YOUR POOL. REGULARLY. TAKE THIS SERIOUSLY.

This is a recurring post, regularly updated with new information.
Here are the essential items you should never pack in your checked luggage so you have them close when you need them.
All you need is a standard plastic grocery bag (nothing fancy). Start by placing one cup in the bottom of one side of the bag. Then, give the middle section of the bag two tight twists. This helps create a separation between the two sides and stabilizes the base.
Now, place your second cup on the other side of the bag.
When you lift the bag by the handles, you’ll notice that the cups balance perfectly on either side, almost like they’re in separate pockets. The twist in the center acts as a divider that prevents the cups from knocking into each other or sliding around. The added tension in the bag also keeps it firm enough that the cups stay upright as you walk.
