Well, that is nicer and quicker than mine I think - kudos! :-)

Hmm, interesting, seems to work ok for me:

cat multiline.txt | perl -e ' while ( <> ) {

The removal of the first empty line is left as an excercise to the reader...

You shoud not need the -static flag. I assume that libRmtDirTree.a is the static lib you try to add? If removing the -static flag does not help, try to simply add ./libRmtDirTree.a at the end of...

Hia,

this is a very low priority request, but I am slightly annoyed by the behaviour of the [ CODE ] tags in the message editor. They behave assymetric in the sense that the opening tag is...

HFS seems to resize, too:


jonas /tmp : mkdir test
jonas /tmp : l -d test
drwxr-xr-x 2 user group 68 Feb 19 09:58 test/

jonas /tmp : touch test/null
jonas /tmp : l -d test

For what its worth, check out the readline library. It is somewhat more work than getc/putc, but in many many cases its very much worth the effort: you get command line editing, command line...

1024 is *not* the disk size - that is easy to verify by creating a large file in a directory:


jonas merzky /tmp : mkdir test
jonas merzky /tmp : ls -ld test
drwxr-xr-x 2 user group 68 Feb 19...

Also 'nmap localhost' will tell you what local services are up and listening on some port.

Or, to check open ports for a remote host, use nmap. For http, check if port 80 is open, like this:


jonas merzky ~/Mail/now/old : nmap www.google.com

Starting Nmap 4.53 ( http://insecure.org...

Hi Neo,

thanks for your reply!

I agree abut your remark as distributed architectures. This is my day-job, and I like it a lot :-)

I did not make the problem clear enough I think: the...

Hia all,

I am not sure how many people actually follow the HPC forum on unix.com, but you may be interested in discussing the following (academic) problem:

Assume you want to run a *very*...

I am not sure, but I think that is C++? Despite the 'Cout' ;-)

The you can try the C++ way:


#include <sstream>

...

std::stringstream ss;
ss << "INSERT INTO movie_info (movie_title ,...

I don't think that trial/error would be so tough. In pseudo perl code:


my @all_libs = split (/\s+/, `ls $LIBPATH/*.a`);
my $good_libs = "";

# get number of unresolved messages w/o any...

Wouldn't you avoid the strok completely with the following



#include <ftw.h>
#include <stdio.h>
#include <errno.h>
#include <string.h>

char filenames[500][256]; // use your local file...

But this is, sorry to say that, not necessarily correct: it may remove spaces from within valid data items, too. So, you would need to anchor your perl regex to a '|'. Easy to do, but not really...

Most likely, you have mp3 files which have single quotes in their file name, like



Silly/1986_-_Battalion_D'Amour/Silly_-_Battalion_D'Amour_-_01_-_Bataillion_D'amour.mp3You can fix this by...

Running the script: you can simply put the script (path + name + arguments) on a single line. Your local.rc could look like this


#!/bin/sh

# This script will be executed *after* all the...

If you use sftp, then ssh is likely to work, too? Then just do

ssh name@B.remote.net stat -f "%z" /location/of/large/file

See 'man perlrun', and check out the options -n -a -l -F and -e.

$" is also known by its long name $LIST_SEPARATOR (see 'man perlvar'), which explains a lot I guess ;-)

'[1..29]' is an array...

@Neo:

Oh yes, I can only confirm what you are stating :-) "One persons service is another persons application".

Thanks, Andre.

We can probably discuss endlessly, and its fine if we have a different perspective on the topic. But for the sake of discussion, I'd like to reply anyway: it is the area I am working in, and I have...

That may be true if you look only at the hardware. The other part of HPC is the software which is tweaked to actually fully use the hardware capabilities: that most people have the equevalent of a...

After completing the script, I still can't reproduce your output: those seems wrong. Fir example, I can't find the line ending not in NULL, but in 2.23e+23 -- that value is simply gone, but according...

Vi is installed on virtually any unix system. Its extremely fast, scriptable, and very feature rich. It has a plethora of commands which support common editing tasks when coding.

Most of that...
