I find searching bash(1) just fine with less(1) and do it quite often. The groff mailing list, the main discussion point for all things troff, is slowly chipping away at adding mor…

`info foo | less' has it produce the whole "page" as plain text, suitable for easy reading and regexp searching.

If it's not thought interesting then it won't meet the front page?

Dupe. https://news.ycombinator.com/item?id=5872550

Is this not equivalent and avoids running grep(1) once for each path? find -exec grep -iH ${1?} {} + Though it still runs grep on directories.

OK, I've gone and read the OP's text rather than just the quoted part. It seems he's talking about combining multiple X screens into one logical coordinate space, like I expect one…

Coordinates in the X protocol are signed 16-bit so a screen can run from 0 to 32,767 along an edge. I agree though, the initial complaint is unclear and may be about something else…

Yes, C across AIX, Suns, Silicon Graphics, whatever those HP ones were, and others. Platform differences were common, bugs rare because many had been before me and they could alway…

Yes, because of the stableness of the C compiler, bigger test audience, etc., compared to a new language under rapid development.

This is flawed AFAICS. It assumes that because 1.0 is fixed in specification that there are no bugs in the implementation. To return to my original point, these smart guys are on t…

Sorry, I don't understand. You seem to be saying there's only two versions of the compiler, one written in a foreign language, e.g. C, the other in a subset, e.g. Gosub, called G-2…

That's not how the books say to do it, and you're right, given who created Go you'd think they'd know this stuff. :-) Many generations of the compiler are created. Let's say the co…

Seemingly often enough that it deterred them with Go. No, you may not be able to revert to before the bug was introduced as it may be the bug was there ever since that feature was …

The Go developers have said they deliberately didn't try and write Go in Go because they've done that with other languages, possibly Alef, I forget, and a bug can arise where the f…

But then the debugger can't be called ogle.

Pre-vim, one would get quite proficient at judging line distances, e.g. 11yy, through practice. Mind you, that was probably helped by text being a fixed size on a serial terminal a…

Here's a £ sign for someone to edit in.

It's not that I'd use Perl for the task, just that I don't think rsync is special. Indeed, rsync has the overhead of forking a child and communicating empty/'s bareness.

This Perl beats rsync by quite a margin here. perl -e 'opendir D, "."; @f = grep {$_ ne "." && $_ ne ".."} readdir D; unlink(@f) == $#f + 1 or die' It goes a bit quicker still if @…

I often think it would be useful for a filesystem to provide a digest of a file's content. It's the FS that knows when the file's content changes and the digest is out of date, and…

This team of about 10, was it at Google or elsewhere? Wasn't sure given the higher-level context.

It could be better bash, e.g. using [[ instead of [. Also, curl -s https://api.github.com/users/$2/events/public | grep "\"gravatar_id\":" | sed -e's/[,|"]//g' | head -n 1 | awk '{…

Would be nice if the title had a few words describing what it is.
