@edwinksl we need shotguns.

edwinksl

@Rinzwind woah that escalated quickly

Rinzwind

@edwinksl typical american response :=) -> an animal bugs you get a shotgun

terdon

@Rinzwind Wow. Not only do you blithely pass the blame on to someone else (you're the one who mentioned shotguns!), you also go and call a diamond moderator an "animal".

I just hope you meant Boris.

Rinzwind

@terdon "no glaring pls, dino with short arms" <- dino = animal

terdon

Aaaaah!

Rinzwind

4:05 PM

:P

eh

terdon

Still, everything I said stands. You did pass the blame for something you brought up and you did call a mod an animal. That the particular mod in question happens to be an animal only makes it slightly better.

Rinzwind

SETHY!

Serg

grrr, i hate it when there's a question i can answer , but I'm on a goddamn train and have no access to my tools atm

@Rinzwind no Sethes around, only Serges

@Serg that was an outcry for help >:)

Serg

@ThomasWard ok, close enough, lel

also . . . gotdammit, dev boards for academia are eggspensive

I need a board that is like 175$ for students. For non academic folks it's 225$ or so.

at least i feel less bad about spending on a board than on a textbook

Rinzwind

I love man page answers <3

I just noticed we have both virtual-terminal and virtual-console, and neither is a synonym of the other. I suggest virtual-terminal be the main tag since that seems to be a little more popular, judging by searches of the site (either through the the built-in search engine or through Google) for "virtual terminal" and "virtual console". I think it doesn't really matter much, though.

@Rinzwind I know ... you once said that they bring you many upvotes ... :D

terdon

@EliahKagan Sounds good to me. I don't have time to do it now though, could you please post in on meta?

That's a good idea anyway since it leaves an audit trail, so to speak.

Eliah Kagan

Yes, I'm going afk for a bit now but I'll post about it soon.

karel

virtual-console is less confusing than virtual-terminal if for no other reason than that it looks more like a console than a terminal.

I'm finally on my laptop , yasssss !!!

Eliah Kagan

@karel I don't really follow, but can you expand on that in an answer when I post on meta?

hi

Serg

Oh, this is bad, very bad @_@ my lower back is hurting today

semester just started, it's too early for chiropractor visits

Thomas Ward

@Serg lies it is never too early for that

Serg

T_T

TheXed

@Serg lay on your stomach...

very practical and it works...

Thomas Ward

@Serg lay on your stomach, and prepare yourself. There will be a fix for your back incoming.

Just lie there and relax...

... and prepare.

TheXed

5:28 PM

@ThomasWard it could just be muscle...in that case prepare for what?

Thomas Ward

pulls out a taser and a hammer

Oh, nothing really, just some adjustments that need to be done

TheXed

No if it something more serious then that then...yeah he might want to prepare...

lol

Thomas Ward

in other news, @KazWolfe has a lot to learn about being chill and being a moderator at the same time lol

runs and hides

Q: These tags are [virtual-]ly the same!

Right now we have separate virtual-console and virtual-terminal tags. One should be made a synonym of the other, but which one should be the master tag? We have another question on meta about this, posted well over a year ago, but it has languished unanswered and also seems like it's asking abou...

terdon

5:34 PM

And then some! Thanks :)

Serg

@TheXed @ThomasWard I'm at work. I can't just lie down anywhere

Also, anybody wanna read my poem about awk and python ?

Actually , wait . . .no

karel

@EliahKagan Yeah sure, I can or anyone else can post it in Meta. The console looks like a server login which looks like a console. It may be a petty distinction, but just the same it may also help new users to keep it straight.

Serg

Feck, feck, I fecked it yup

I misunderstood OP's question. Fixed now

@terdon Perl review pls ? unix.stackexchange.com/a/338382/85039

Can I simplify that any more ?

Ah, feck again . . . double quotes in wrong place

terdon

5:49 PM

@Serg a little:

perl -ne 'chomp; open($fh,$_) or die; print "$_\n\"\"\n";while($line = <$fh>){ print $line}' filenames.txt

karel

@EliahKagan I decided to post it anyway. Now I'm going to get to hear the story of the blind men and an elephant, but it still looks like a console to me.

Eliah Kagan

:) Thanks for posting. I think of a command-line interface as a terminal rather than a console, which may be why I didn't understand you initially. I don't think I have any particularly strong reason for thinking of it one way and not the other, though.

terdon

@Serg or, you could simplify a lot:

perl -le 'do{print `cat $_`,"\"\"";} for <>' file

Serg

Uh . . . that's probably way above my head

Anyway, answer fixed, in format as OP wants

So yay, everything is smexy and as it should be

@terdon add print $_ before do{..} :) OP wants to have filenames included in output

terdon

@Serg Thanks, I'd missed that. I added an explanation as well. It's not as weird as it looks, the only new thing really is the do {} for @list

Q: Migrating system to new machine

I have been trying to follow the instructions of the top answer here: link but there are a number of things I don't understand. (Both machines are Ubuntu 15.10 64bit) Use scp or rsync or even a flash drive to transfer your home directory (~/, ~/.), the source list (/etc/apt/sources.list) an...

migration

he keeps pm' ing me :X

Serg

@terdon AHA ! That's like list comprehension or map() in python ! smexy :D

terdon

@Serg Yes, perl also has map{}. But do{}for is preferred syntactically because map{} is designed to actually modify the array it is mapped to. Practically, it makes absolutely no difference and do{something} for @list is equivalent to map{something}@list but I've been yelled at by more experienced people.

But no, sadly, not like list comprehension. That is, I must admit, an absolutely awesome feature of Python.

Thomas Ward

@Rinzwind should be handled now

moderator diamonds scare people

terdon

I mean, you can't do @newList = [ $x for $x in @oldlist ] or anything like that in Perl. Not to my knowledge, anyway.

@ThomasWard OP is on 15.10, not 6!

Thomas Ward

updated

now silence mortal.

bleh i broke spf

screw it

Eliah Kagan

6:14 PM

@ThomasWard The OP's using 6.06? Their post says 15.10. (Which is also EoL of course, but your comment is about 6.06. Am I missing something?)

Thomas Ward

@EliahKagan already resolved

see previous four messages, I already revised

if they complain, it'll get squished.

terdon

What in the world is a failsafe shell, anyway?

Thomas Ward

evil

Serg

@terdon how's this then ?

$ perl -e  '@list = ( 1, 2, 3   );do{push @newlist, $_ + 1} for @list;do{print $_,"\n"}for @newlist'
2
3
4

probably still not close enough to list comprehension ?

terdon

Fair enough, that'll work.

I meant that it doesn't have that nifty list = [ x for x in list if x >10 ] thing.

Rinzwind

6:18 PM

:)

terdon

Although you can usually do it with grep. perl's grep is really powerful. Checkout perldoc -f grep

    grep BLOCK LIST
    grep EXPR,LIST
            This is similar in spirit to, but not the same as, grep(1) and its
            relatives. In particular, it is not limited to using regular
            expressions.

            Evaluates the BLOCK or EXPR for each element of LIST (locally
            setting $_ to each element) and returns the list value consisting
            of those elements for which the expression evaluated to true. In
            scalar context, returns the number of times the expression was

"not limited (!) to using regular expressions"

Serg

But we can approximate it

$ perl -e  '@list = ( 1, 2, 3   );do{if ($_ >= 2){push(@newlist, $_ + 1)} } for @list;do{print $_,"\n"}for @newlist'

terdon

Oh, yes, of course. it's just the syntax I like in python. Especially for things like

list = [ x for x in otherList if somefunction(x) or otherFunct(x) and oneMorething(x) ]

It doesn't make up for significant whitespace, but that, at least, is useful!

:P

Serg

That syntax was confusing the heck out of me when I just started doing python.

But it is indeed quite elegant

terdon

@Serg Me too.

But yeah, it's grown on me.
