@terdon it seems to me unintentional.

At least you tried to help. Some miscommunication. That happens unfortunately

@Tim Oh, it was completely unintentional!

@Ungeheuer Yeah. Although Michael does raise a good point about it's being odd.

I wonder what IRC it was, in superuser.com/q/543625/69787

The IRC channels I've been in are sometimes quite bad. I had an unpleasant experience in #lua some days ago, when I randomly attacked, for, if I recall correctly, wondering why just typing 1 returned an error.

By people who sounded like they were 12 years ago. I hope for their sake they were, but otherwise they were very immature.

In any case, I doubt that even in those channels people would idly stand by and watch someone offering criminal advice. Though I wouldn't want to test it.

@Kusalananda I rolled your edit back since gawk is how GNU awk is often installed and I wanted to make that clear (gsub is a gawk thing AFAIK) and there was nothing GNU specific about the sed. The -E flag is not POSIX, but it is widely supported. Including by GNU, BSD and even busybox sed, which cover most cases right there.

@terdon I think gsub is available in all versions of awk

it's mentioned in: pubs.opengroup.org/onlinepubs/9699919799

@Jesse_b Oh hey, yes. It seems to be POSIX! pubs.opengroup.org/onlinepubs/009695399/utilities/awk.html

Cool, thanks.

Sorry, @Kusalananda!

@terdon I mentioned GNU sed specifically due to the \S, and I changed gawk to awk due to the awk in the immediately following example.

Linux users have GNU awk as awk, and most others know to use gawk anyway to get it.

I Didn't actually look at the awk script as such too closely...

... but it seems to be POSIX, so "GNU" was not needed. The sed code is however GNU sed.

... or you would use [^[:blank:]] in place of \S.

wat up @terdon, @Kusalananda, and @all =)

@all would probably be an annoying feature

@Jesse_b I'm checking ina couple of times a day, but I'm mostly trying to rest my brain a bit over the summer. How are you doing?

@Kusalananda I'm well. I should probably rest my body...my brain is always resting though as it doesn't get much use :p

:-)

@Kusalananda Do you have any plans for the summer?

@Jesse_b I'm on my third week of vacation right now, out of seven. No plans. Saw my sister and my 91 year-old grandmother last Tuesday, and my sister's almost-two-year-old son (17.5 kg * 4 hours = lots of workout).

@Kusalananda Tell me about it, my son is only like 8kg and he wears me out fast

Parents get a free workout daily it seems :-)

My wife can hold him seemingly forever, I get tired after like 10-15 minutes

There's some secret technique to it, I'm sure.

mom-strength is more powerful than dad-strength

but also the more muscle mass you have the less endurance you will have, more muscle=more oxygen requirement

@Kusalananda are you sure about that? The -E flag is pretty portable. Does bsd sed not understand \S when using that flag?

(empty line after last command too)

So, no, BSD sed does not support \S, regardless of -E.

GNU sed does not need -E to support \S.

Huh. I stand corrected, thanks. I thought \S was an ERE thing.

No worries. No, it's a GNU thing :-)

... taken from PCRE, but incorporated into GNU sed as a BRE.
