I am trying to use the csplit file on a file that contains records that have more than 2048 characters on a line. The resultant split file seems to ignore the rest of the line and I lose the data.
Is there any way that csplit can handle record lengths greater than 2048?
Thanks (0 Replies)
I'm running a simulation (programmed in C) which makes calls to gnuplot periodically to plot data I have stored.
First I open a pipe to gnuplot and set it to multiplot:
FILE * pipe = popen("gnuplot", "w");
fprintf(pipe, "set multiplot\n");
fflush(pipe);
(this pipe stays open until the... (0 Replies)
As part of a quiz assigned during my unix class I was asked to write a program to ask for a file name, print read errors, and "reverse elements in a list."
I used the 'tac' command in my solution, however, I was then lectured for 5 min about the "limitations" of the 'tac' command and how a 'for'... (6 Replies)

I have a 1G full duplexed eth0 card and I am suspicious that this may be causing the problem. My eth0 settings are as follows:

Hi,
I recently started working with Solaris, and what I noticed is that a lot of commands I used to regularly use don't work, like sed -i and grep -r. I have found work arounds for these problems though but it's a pain in the ass.
I'm just wondering why they decided not to include these handy... (4 Replies)
Guys: I have a customer using the 'pdftotext' utility under Linux. PDFs are received via email, converted to text, etc. and it has worked nicely for years.

dbix::password
Password(3pm) User Contributed Perl Documentation Password(3pm)NAME
DBIx::Password - Allows you to create a global password file for DB passwords
SYNOPSIS
use DBIx::Password;
my $dbh = DBIx::Password->connect($user);
my $dbh = DBIx::Password->connect_cached($user);
$dbh->getDriver;
DBIx::Password::getDriver($user);
DBIx::Password::checkVirtualUser($user);
DBIx::Password::clearConfig();
DBIx::Password::readConfig("$ENV{HOME}/.my.secret.file");
DESCRIPTION
Don't you hate keeping track of database passwords and such throughout your scripts? How about the problem of changing those passwords on a
mass scale? This module is one possible solution. It stores all your virtual users and data in /etc/dbix-password.conf. For each user you
need to specify the database module to use, the database connect string, the username and the password. You will have to give a name to
this virtual user. You can add as many as you like.
I would recommend that if you are only using this with web applications that you change the final permissions on this package after it is
installed in site_perl such that only the webserver can read it.
A method called getDriver has been added so that you can determine what driver is being used (handy for working out database indepence
issues).
If you want to find out if the virtual user is valid, you can call the class method checkVirtualUser(). It returns true(1) if the
username is valid, and zero if not.
Once your are done you can use the connect method (or the connect_cache method) that comes with DBIx-Password and just specify one of the
virtual users you defined while making the module.
BTW I learned the bless hack that is used from Apache::DBI so some credit should go to the authors of that module. This is a rewrite of
the module Tangent::DB that I did for slashcode.
If your program does not need the system-wide information stored in the /etc/dbix-password.conf file, you may use the clearConfig() and
readConfig() functions to get the data from another source. At any time, readConfig() may also be used to merge the data from another file
into the currently-loaded configuration.
Hope you enjoy it.
