When i pipe commands through 'less' in console, i get a load of garbage mixed into the results, and no colors either. Mainly the letters 'Esc' printed a couple of times on each line.
I had been messing about with my bash config files but i can't see anything in there to affect this. If I pipe through 'more' there is no problem, only 'less'.
I actually have two reasons for posting this. One is to see if there's an actual name for characters like this:Hopefully that will show up correctly for you. If not, it's a little box with four numbers in it, one in each corner. I don't know their name or their reason for showing up, so it's hard to look for help.
My main problem, though, is that I wrote a program that prints some output to a console using ncurses as it runs. These characters show up on the console, seemingly at random, and disturb the whole thing. Sometimes I'll also get sets of characters like "[13;" I'm not printing anything bizarre on there, just strings and floating-point numbers.
Just recently got a few printers connected to the network at my shop and I've managed to get them connected in with samba for the linux clients. Whenever I try to print from one of the clients, the printer will click on and whiz away, but only prints on the first page stuff that looks like this:
Code:
%!PS-Adobe-3.0
%%BoundingBox: 38 24 574 768
%%Title: Enscript Outpu
%%For: User N
It seems to me that the printer isn't processing the postscript data properly (or I'm just not sending it in the right format) but I'm at a loss as to how to go about fixing it.
I would like to keep this simple and if possible use a piped command as opposed to an all out complex method.I have a script that does many things for me, and one of them builds a basic simple system report (I know about lshw, but this is for me to learn as well as be functional)
I would like to add another pipe to remove the"model name:" portion.I do not really want to use the store in a variable first solutions if I can help it.
My root partition /dev/sda1 is 24.41 GiB with 10.48 GiB used. How can I tell if I have inadvertently placed a bunch of garbage on this partition? Also, should I, and I use the term loosely, 'move' certain directories to my home partition /dev/sda3? (118.77 GiB with 3.14 GiB used)
Right now I believe that, rightly or wrongly, if I screw up my system, all I need to do is install my Clonezilla image back to /dev/sda1 and I will have a 'mostly' working system. If I 'move' anything out of /dev/sda1 to /dev/sda3, will this hold true? Or am I out to lunch on this assumption anyway?
I'm struggling on installing a KONICA-MINOLTA printer magicolor 4695MF printing properly with Linux Mint Debian Edition (up to date). The test page works fine...
KONICA-MINOLTA delivers 2 PPDs: one for standard printing and one for OpenOffice printing (available on the KONICA-MINOLTA support site).
Leaving a side the one for OpenOffice which is poor in using the capabilities of the printer, I concentrate only on the global one (M4695PX.ppd).
It's much more difficult for other applications, starting with EVINCE: some PDF files are printed properly (i.e. those generated in OpenOffice by the CUPS PDF printer), others come out as one only blank page, regardless to the original length of the document.
So documents received from 3rd party may be "printable" or not. And trust Murphy, the most critical aren't printed...

I'm running a standard 13.1 32 bit install with an HP deskjet 990C, run off of USB. Until today everything has printed properly. Now nothing prints. Nothing has been installed unless it came through slackpkg, and yes it is still on the correct setting for arch and revision. CUPS shows printer as installed, accepting jobs an idle. No error messages are appearing but nothing is reaching the printer. The info I can glean is from the error logs in CUPS:

I've been using slackware since slack12.2 on a linux box as router at home with some servers running on it and it's been awesome and performs perfectly. But since I upgraded to slackware 13 there is something that drives me crazy. I use to manage the box through SSH but sometimes I have to do some configs localy and it's almost impossible because I have constant echos of some traffic the iptables is forwarding to other hosts on the network.

View 2 Replies View RelatedI am doing this project for our school. Basically we want to pipe all incoming emails to a script which filters out certain messages (not only spam but duplicates, large messages, etc). If they fail certain criteria, the script simply does nothing.If they pass , then the script should pass the entire message (headers and body) back on to qmail to send. The piping part is not a problem, but I am stuck with the next part. Is there a way to pass the headers and body back to qmail for it to process and send, as if it received it the first time?Some details:A catchall email account is created via Plesk control panel on linux (centos).THe .qmail file in /var/qmail/mailnames/domain.com/catchall/ is edited to include the line:-|/path/to/pipe/handler.phpThe handler.php file simply reads the entire message (headers and body) and they are then parsed and analysed.

Code: Select allmplayer audiofile.m4a 2>&1 | awk -vRS="
" '$1 ~ /A:/ {print $0; fflush();}'
Instead of a steady output of lines to the terminal, output only occurs after a few seconds, between 6 or 12. This happens whether the input is from mplayer or avconv/ffmpeg. This never used to happen (a few years ago) so I wondered whether an awk update caused this to happen.

First time I've done this in awhile Upgrading my Slackware64 -current VM, following the standard routine that has always worked in the past -
Code:
slackpkg clean-system
slackpkg install-new
The clean-system removed 2 packages -
util-linux-ng
eggdbus
Installpkg will no longer work, complaining that the rev command is not found. The problem hit with the removal of util-linux-ng. I cp'd util-linux to ~/. Extracted with tar and executed the doinstall. Fixed.
I was wondering if it is possible to have a garbage collector in C, and would it be too difficult to create?

I'm interested in writing a generational garbage collector in C++. This is for a Python-like programming language project. I have used Boehm's garbage collector before, but I'm worried that it will have noticeable pause times (unacceptable for interactive programs). Since I can't really find any other C++ established GCs out there, I have been thinking of simply writing my own.
However, there are two essential ingredients I need for this:
- Some kind of write barrier mechanism that will notify my collector when something is written to a part of the heap
- A way for me to know the addresses and sizes of the stack, heap and global storage (the root sets)
how to implement write barriers (and how to get the stack, heap and global storage information) on the Linux platform? As an alternative, if you know of C++ GCs other than Boehm, I would also be interested.
if I open Yast2 via SSH I see the garbage (code page related issue; similar to this). If I set some other than UTF-8 in PuTTY (KOI8-U, iso-8859 etc) Yast looks good, but then the same problem appears with Midnight Commander. How can I have Yast to use 'right' UTF-8 instead of any legacy code pages? Or how better deal with the situation?
View 2 Replies View RelatedI've setup a git-svn repo with cron to fetch from the svn repo daily. I have a script to do the fetching, and this is what is invoked by cron. Everything is fine with the repo, and the script works fine when executed manually. However, when it runs under cron, empty files get dropped into the .git directory. The files have names that look like they are some base64 output, e.g. juTrvjP6m8 and kcKf3hu3b4. Two of these files show up for every cron run. I thought these might be commit hashes, but they're not, git-show says it's an unknown revision. I set-up the repo as follows:
[code]...
The last line pushes the repo to a separate (bare) public repo from which others can clone. I'm piping the output from the cron job to a file, which looks like this:
[code]...
The line "fatal: unable to run 'git-svn'" is alarming, but the fetch seems to go ahead anyway. Where are these empty garbage files coming from, and how to stop them? Am I in for bigger problems in the future?

The code below prints garbage if I use puts() but it is fine if I use printf() instead (see sample of output at the bottom of this post). The odd thing is that the mess always starts after exactly eight properly printed characters. That sort of regularity can't be a coincidence, can it? It almost looks like an encoding issue (I'm using UTF-8) but if it really is, then I don't understand why the printf() is unaffected.
Code:
#include <stdio.h>
#include <string.h>
const char *nChars (const char *, int);
int main (int argc, char * argv[]){
char * name ="Count Dracula++";
int len = strlen(name);
if (argv[1] == 0) argv[1]="printf";
printf("--->%d characters", len); .....
