Because there's no such thing as an assignment operator in bash. Everything is a string token at first (even numbers aren't number unless you're in arithmetic evaluation context), and then tokens get interpreted in various ways once split by whitespace. x = 3 happens to be three tokens, the first one being the command 'x', the other two being parameters '=' and '3' to command 'x'. x=3 is one token and it doesn't mean assignment unless it's in the command preface where assignments take place.

Tomatoe Tomato.

Actually I also do $(($x+1)) as per example in http://pubs.opengroup.org/onli.... (Arithmetic section)

But I think I will have to revise that behaviour as it could allow circular problems or "arithmetic injection". Thanks for making me aware of this.

The reason they have an IDE for it is because you can use it to do incredibly complex things, like design GUIs that tie in administration elements from Active Directory, SANs, switch configuration, virtual infrastructure configuration and deployment, and computer administration-- all in one language with a common syntax.

Why would you want to do that with a scripting language ? I thought that's what MMC was for.
While nice sed tetris isn't a good idea either.

The only web developers who still have such security bugs in their software are 1) lazy 2) incompetent 3) not interested in security or 4) have been asleep for 15 years. For whatever the reason is, it's not wise to use their software!/p.

That's like 90% of all developers :D.

Oh? Why wouldn't I just read /run/systemd/journal instead? [unplugs disk that /var is mounted on and starts box] var.mount mount process exited, code=exited status=32 hmmm, no information on what went wrong?

That's what systemd tells you not the output of the actual mount utility. It could lie. What if mount fails because of a severe filesystem error ? What if the initrd is broken and the actual mount helper utility is not present ?

P.S. Weren't you the genius who wondered why "we" don't know what happened before time and space began? Where do I sign up for your newsletter?

No, I was the "genius" that got confused because the medium article mentioned 2 BIG BANGS. That send a red flag for me because I was taught that yes, we can't look "before" the big bang because there simply was no time. And offcourse cosmic inflation happened after the big bang !

Something needed to happen to set up the initial conditions for the Big Bang, and that “thing” is cosmic inflation, or a period where the energy in the Universe wasn’t dominated by matter (or antimatter) or radiation, but rather by energy inherent to space itself, or an early, super-intense form of dark energy.

PS. Nice Ad hominem.

But If you can't write to these log files because your root or /var filesystem doesn't mount
then you would have wished for stdout/stderr on the console !

Yet there was a time in the distant past before any of those things had formed, shortly before the Big Bang, where the Universe was still filled with light.

I thought spacetime started with the big bang and we had no insight into what came before ?
The article says that the fabric of space was expanding and the big bang was an event that got its energy from spots of crumbling spacefabric (bad analogy) ?

This process, of inflation ending and giving rise to the hot Big Bang, is known as cosmic reheating, and as the Universe then cools as it expands, the particle/antiparticle pairs annihilate, creating even more photons and leaving just a tiny bit of matter left over.

Were there 2 big bangs: The one that inflated space and the other one (recombination) that decoupled matter from photons ?
Have you just created an extra "big bang" to be able to explain the question and don't you regress now to the question: Where did spacetime get the energy to begin with ?
