The command sort is used to sort files line by line. Lines starting with a number go first. Lines that come next in order go alphabetical with uppercase letters appearing before lowercase ones. Use cat to create "testsort" for the example. ~/Test>cat testsort A line 1 a line 2 8 line 3 line 4 5 line 5 ~/Test>sort testsort 5 line 5 8 line 3 A line 1 a line 2 line 4 R sorts by using a random hash of keys ~/Test>sort -R testsorta line 25 line 5A line 18 line 3line 4 ~/Test>sort -R testsort5 line 5A line 1a line 2line 48 line 3

Lemon-Lime Gatorade and crushed ice is (almost, coffee still #1) my new favorite beverage. I know it seems wrong, but it’s pretty nice on hot humid days - especially when I’m waiting for Windows 10 Update Assistant to finish upgrading Windows 10 on my Lenovo ThinkPad. So slow, I know I should be patient, so I finish some other work I’m chipping away at on another Linux laptop. I downloaded the latest Win 10 64 bit iso also just in case I have to build from scratch, but I wanted to have my current configuration updated by the Update Assistant so I could experience the method many users would choose.Thus, the cold beverage on such a hot day. (Which I just spilled)This entire exercise started this morning as a plan to play around with the new Windows Command line. The iso I had on hand was ve
Earthquake at China Lake, Power outage in NYC, tropical storm, flooding, strong thunderstorms and more strange weather - all random events with very little in common other than a cautious reminder that things happen. Sometimes you can avoid trouble, sometimes you can’t. Now there are those who can’t get into enough trouble, so they look for it. The idea that there are people toying with the idea of walking into Area 51 (Groom Lake)to see what’s there. This seems like a bad idea. You’re either going to get in trouble and have a big let down, or you might actually find an alien who is famished. That would probably be much worse. If there are actual space aliens at Area 51, leave them alone. They’re probably doing important work redesigning the next iPhone, or working on Hot Fixes f
What happens when +90% of the jobs are not automated? No longer will we need doctors or surgeons, instead hospitals will just need a single person to decide on moral choices. More of a supervisor that really their time will be spent monitoring the machines. Kids will have no idea humans would drive trucks or even personal vehicles. They'll say "Why did you not care about safety and efficiency. Robots/Machines are better in every aspect." Side note: any movies like Terminator or iRobot will no longer be legal to watch Population Control: Concerns of overpopulation begin to be debated by the top 1%, with no longer having to work or work +40hrs a week births begin to increase. Wars are fought in the cyber world, no longer will militaries need boots on the ground as much rather than boots ...
