<0> like while true; do sleep 1000000000; done| myprog
<0> but simpler
<0> is there any /dev/nothing ?
<0> ?
<1> The_SB: I found the book a bit tedious. MJD is covering one code, then goes on to discuss some modifications, then a lot of discussion. I sort of anticipated it.
<2> like /dev/empty
<3> like /dev/null ?
<0> no /dev/null gives eof immediately
<1> The_SB: I'd better go to sleep. Hopefully, I'll be more productive work-wise tomorrow.
<0> i need /dev/wautforever
<0> i need /dev/waitforever
<4> OK bye
<5> /dev/zero ?
<1> The_SB: I'll probably won't IRC unless I encounter a problem.
<0> pravus: oh right
<1> The_SB: I had a problem where my code did not work, because I wrote ">" instead of "->".
<2> zero always has zeros in it..
<0> i though /dev/zero would give stream of 0-bytes
<0> thanks
<1> The_SB: viva la minute difference!
<4> rindolf: C U :-)
<5> Mish: it does
<1> The_SB: good night.
<0> pravus: wait then it's bad
<1> The_SB: do you have work tomorrow?
<0> i need device that gives nothing but not eof
<4> sure
<5> if you just want to open something that blocks, use a FIFO
<6> "xp_" at 63.103.227.2 pasted "ParseRecur returns nothing?" (23 lines, 579B) at http://sial.org/pbot/18066
<2> Mish: just make a temp named fifo in /tmp.. omen it for reading and writing.. and just never write to it.
<1> The_SB: did you see my email?
<0> not good
<1> The_SB: about AP5, etc?
<7> i'm just going to update that box to -stable and hope that's it
<0> i need the open to succeed
<8> help please
<0> i don't want it to block in open
<0> but in read
<2> the open WILL succeed if you open it for read and write.
<5> Mish: mkfifo
<0> no, i open it RONLY
<4> at work yes - I wil try to see what details are needed
<0> RONLY RONLY RONLY
<0> sorry RONLY
<9> got a stupid question.. how do I do this more efficiently, hopefulyl only using one line? http://rafb.net/paste/results/1BYwYW31.html
<10> The paste 1BYwYW31 has been moved to http://erxz.com/pb/1753
<8> dkr?
<2> Then open it in non blocking mode.
<5> leku: for my $line (@{ $_->{action} }) {
<0> fifo might be good idea though
<0> i'll try prog </tmp/fifo 4>/tmp/fifo
<9> thanks
<0> betterm prog 4>/tmp/fifo </tmp/fifo
<0> then it prolly not block in open
<0> right ?
<2> or just: sleep 10000000 | prog
<0> i don't have control over open flags , it's external app
<2> or even: perl -e 'sleep;' | prog
<0> JohnQ: yeah that'w what I'm doing now
<11> GumbyBRAIN: you have 7 alleles in common with PerlJam
<0> i'm thinking of reducing elephant footprint on my process table
<12> As in you have all the more common.
<11> stupid tab completetion, that should have been perlbot
<2> why? you doing this a million times or something?
<5> simcop2387: how do you blame that on tab completion?
<0> have those junk processes
<0> s/have/hate/
<5> simcop2387: nm... rainbows
<2> process (single)
<11> pravus: i hit tab
<0> that have tendency to become zombies
<2> "perl -e 'sleep'" can not become a zombie.
<0> no "prog 4>/tmp/fifo </tmp/fifo" did not work
<0> why "perl -e 'sleep'" can not become a zombie.
<2> what would it be waiting on? It has no children...
<13> JohnQ: Zombies aren't the ones who are waiting..
<13> But it can't become a zombie because bash eats them properly
<8> buu can you help me with my ParseRecur problem?
<2> Mish.. if it really bothers you.. you can make only one such process... make a fifo... make a program which sleeps, and redirect it into the fifo... and then open the fifo for reading as often as you want.
<13> xp_: Does it involve working?
<8> no, it is all fun
<8> http://sial.org/pbot/perl/paste
<13> Awesome url.
<8> thanks
<0> **** 'prog >/tmp/fifo' blocks until someone opens it for reading
<0> and 'prog </tmp/fifo' blocks, too
<2> of course it does.
<13> xp_: Want to tr a link tha thas code on it now?
<13> Mish: Erm, yes?
<2> Like I said... make a program which makes a fifo, and opens it for reading AND writing... and then goes to sleep. Anyone else can open that same fifo for reading and it will not block.
<8> http://sial.org/pbot/18066
<8> oops sorry :(
<2> Anyway... how can you find out how much memory a perl process is using?
<2> from inside the process
<14> I need to concatenate two paths together.. Is there a portable way to determine which path separator to use??
<2> getrusage does not seem to do it
<16> SummerWO: perldoc File::Path
<10> File::Path. To access this perldoc please type, at a command line, 'perldoc File::Path'. You may also find it at http://perldoc.perl.org/File/Path.html
<13> xp_: What the **** i sthat
<8> buu what am I dong wrong?
<17> hey there. I have a log file millions of lines long. Each line has 9 entries, separated by spaces.
<17> I would like to put each of these into a hash...so I thought I would use a regex
<13> xp_: Seriously, what the hell?
<17> i tried /(.*)\s(.*)/
<14> PerlJam: I do not see it there -- I looked.
<0> how do i do mkfifo in perl ?
<17> would that not give me the first two things separated by a space?
<13> Mish: try mkfifo
<13> jirwin: try split
<16> SummerWO: perldoc File::Spec
<10> File::Spec. To access this perldoc please type, at a command line, 'perldoc File::Spec'. You may also find it at http://perldoc.perl.org/File/Spec.html
<0> why it's not in man perlfunc
<17> buu: thanks
<13> Mish: It is?
<2> system("mkfifo","/tmp/blackhole") and die;
<0> buu: no
<13> Ok, it isn't
<13> JohnQ: Not really, no
<2> it will work for his test
<18> xp: earlier I said: do not use printf if you want printf. You are STILL using printf. Do NOT use printf unless you are using a FORMAT.
<13> Hrm
<13> Wait..
<13> Woah, there's no mkfifo?
<13> Maybe it's in a module someplace
<19> Anyone happen to be doing any perl coding for Asterisk stuff?
<0> WHO STOLE mkfifo ?
<2> just use system man...
<5> buu: POSIX
<13> You've found it!
<0> Undefined subroutine &POSIX::mkfifo called at -e line 1.
<5> the question is: who lost it?
<0> oops wait
<0> forgor use
<18> xp: do you understand what I said?
<0> ok, POSIX::mkfifo it is
<2> Is there really no way to get the current memory usage of a perl script?
<5> doesn't Devel::Size do stuff like that?
<18> The exact memory usage? No.
<0> getrusage
<2> getrusage does not do it.
<0> does perl have getrusage ?
<2> getrusage does not do it.
<0> why not ?
<2> look at the function.. it does not give you that information.
<0> 'integral unshared data size' is not good 4u ?
<0> ru_idrss
<2> it is always 0 ... so... no.
<0> which OS ?
