FWIW - Microsoft originally ran 2 OSes - Xenix and DOS. Xenix was a UNIX clone and DOS later became Windows. It was a business decision to drop Xenix and go all Windows, just like going WSL2 is...

Regarding ZFS, I tend to follow Linus on this. Linus is a smart guy and he knows what he is talking about.


Don't Use ZFS on Linux: Linus Torvalds - Last updated January 10, 2020...

Other the licencing issues, ZFS on Linux is production quality.

I'm no zealot but name me one file system on Linux (other then BRTFS) which has all those features so to say inline :


Builtin...

After thinking about this some more, let me please add....

I have nothing against anyone using btrfs and someday, when it is default on Ubuntu, I will probably follow the crowd and use btrfs; but...

Can you please explain to me what your script means step by step ? Sorry for being blunt but I am comfortable with awk rather than raw shell scripting. However for this problem it does not matter...

Your "sample two script" had two typos in the systemcall, a space before the trailing quote of "my_local_function" and a missing '$' before the 'k':
function my_local_function () { echo @ $1; }...

You do not need to put date, ls, or any other COMMAND to put in quotes when executed in a terminal.

Just like this is enough:
date
ls
w

To actualy work with them, it is suggest to echo them...

As requested:sudo ln -sf /bin/bash /bin/sh
echo "a/b/c/d/e" |
awk -F"/" '{for (k=1;k<=NF;k++) {if ($k == "a" ) {system("my_func_local " $k)}
...

It might also be worth the time to consult the manual page of sed: suppress default printing and selectively print the desired lines.

I hope this helps.

Well, for starters -- it's a pretty silly thing to do, either way. Why do echo "`command`" when you could just do command ?

But the difference is, quotes prevent a string from splitting on...

IMHO, the best book ever written on the subject is: C Programmer's Guide to Serial Communications (http://www.amazon.com/C-Programmers-Guide-Serial-Communications/dp/0672302861/)

Let us start with some hardware first: you want to transmit signals (zeroes and ones) in both directions between two nodes. What do you need? Basically, you need 3 wires: one ground, to even out all...

Thanks for letting me know. I said: many GNU Utilities are coming closer to meeting POSIX requirements.
I should have said: many GNU Utilities, Linux libraries, and the Linux kernel are coming...

Most of your criticisms are quite true! But this one hasn't been true for 10 years. The old threading model -- which amounted to cloned processes sharing the same memory segments -- got thrown out...

No current Linux system meets POSIX requirements for OS or utilities behavior. On a POSIX conforming system, you never have to give a --posix option to make a utility behave as specified by the...

In the beginning, terminals and telecommunications equipment were always attached to serial ports; that's what they're there for. Quite a lot of features -- SIGINT on ctrl-C, EOF on ctrl-D,...

I try to read through all posts concerning the shell and the "standard" utilities and will usually comment if I see something that doesn't look right; but I may miss a posting once in a while. If...

Like Corona688 already said: yes, precisely. The compatibility of UNIX is defined as the guarantee that you can compile the same source code on different systems with the same outcome. For instance,...

Yes. Exactly. The features of the kernel define and constrain what your programs can do. Compare any UNIX-like to the Windows kernel for example.

Do you get disk devices? Yes -- as drive...

1) UNIX used to be a closed-source operating system, yes, made by Bell and AT&T.

UNIX is no longer an operating system, however. That particular kind is no longer sold, and the name is now...

OK, a few definitions up front:

AT&T had a experimental lab, where some determined guys (Ken Thompson, Brian Kernighan, Dennis Ritchie, ...) programmed a OS - the first UNIX. Over time there were...

Ok, let's say a company like Redhat starts a new release. They might go to the grub site and download what ever grub is current. Then they start to work on a release making sure that every thing...

GRUB is often packaged by distributions to make it easier to install and upgrade.

GRUB's very reason to exist is because it uses configuration files instead of finicky bits hardcoded inside the...

As a part of the linux installation process GRUB will be configured and installed. It will search your disk and find other OS, including them into its boot menu. If windows is found, GRUB will...

GRUB is usually installed as part of any Linux distribution installation.

GRUB will chainload your Windows bootloader.

The master boot record (MBR) will locate the active partition and load...
