I'm working on a SBC9261 board with touchscreen, running Linux 2.6.24./dev/ttyS0 is the standard output and /dev/tty0 is the console on the touchscreen.What I would like to do is to clone the standard output to the touchscreen, so the console would be displayed twice.
It would be like :
Code:
~ $ ./whatEverScript > /dev/tty0
but the output would also appear on /dev/ttyS0.
Is there already a program that reads multiple pipes or file descriptors and writes to the standard output (not splitting lines).Like cat, but reading all files simultaneously and preserving lines.It is needed to avoid coding of select/epoll loops or using multithreading in simple programs. Like "select loop for bash".

I would like to get the output from 'yum list installed' from a standard CentOS 5.1 32bit installation on a Intel desktop PC. I would like to do a diff with my 'yum list installed' to figure out exactly what my company customized. I know the docs here have the list of added, deleted and updated packages going from 5.0 to 5.1, but is there a complete 'yum list installed' list somewhere?
View 1 Replies View Relatedhave recently installed CentOS 5.6 Final on TWO DIFFERENT desktop PC's, and, on EITHER ONE, I can not get any sound output when using KMid to play a "standard .mid file (the file I am using to experiment with is "Canyon.mid", from the Windoze Media directory, a fairly standard midi audio file, I should think?!). I have normal audio output on both of these machines (.mp3 files, system sounds, etc.), so the specific sound cards are NOT the issue, here!I am thinking I must be missing something, as both of these PC's are completely different CPU types, etc. as well. The only significant similiarity in the two machines is the complete lack of MIDI audio output!And, yea, the soundcards are BOTH MPU-401 compatible, and they both have irq's assigned to this port (or, maybe just one has an irq assigned, I will have to double check...).

View 4 Replies View RelatedWe make everyday a DB Mysql backup on Linux redhat Enterprise. We are using a bash shell script (and putting it in the crontab) to execute it automatically everyday. We added a line to this script telling, once the backup has completed, to find old backup files (stored on hard disk after each backup) older than x days to remove them. We use the find command (search for file type) with the mtime option and in combination with rm command. Everything runs ok but we also want to add some new code to the same line: If find command cannot find anything or fails, for example if it cannot delete file or fails, send the error message (standard error output) to an error file (like error000001 and increasing) and mail the errorxxxx file to an email address for example to admin@companyname.com. What would be the code for this issue to add it to our find command in the same bash shell script??

View 14 Replies View RelatedI have a computer-based device used in my Ophthalmology office that uses a Compact Flash card as its primary hard drive. This device, and the CF card, are Linux based, and so the card has Linux partitions on it. I need to be able to clone this CF card, using a Windows computer, onto another CF card, to replace one that has failed in one of these devices. Neither Windows XP nor Vista is able to do anything with it.
I use Casper to clone Windows hard drives and partitions which are FAT32, NTFS, etc., but it does not recognize or work with Linux partitions. I need a simple, hopefully free or inexpensive, program that I can install on a Windows XP or Vista computer, which can clone the good Linux based CF card (which would be connected via a USB Reader, or a built-in Media reader) onto a brand-new unformatted CF card that I would buy, and similarly connected.

View 4 Replies View RelatedI need to clone a 160GB hard drive with Linux Mint 9 (not more than 10GB used) to a 30GB SSD that is partitioned carefully (aligned to cylinder boundaries) and is currently running Ubuntu (which I wish to overwrite with Linux Mint 9). The SSD has a /boot partition, / and swap. The source (160 GB) does not have a separate boot partition. Can anyone help me fill in the steps below? /dev/sdc will be the source (160GB) and /dev/sda is the target (with partitions 1,2 and swap on 5).
make a copy of /etc/fstab from the target drive before proceeding. Ready the target partitions. Can I reuse the existing destination partitions on the SSD? Ready the filesystems on each of the target partitions. /boot is ext2, / is ext4 and swap is already set up too. As I said, all contain data (Ubuntu) that I wish to overwrite. So what steps are needed here? Do I need to erase anything (files, etc.) before the copy/clone? next, use dd to copy MBR (right?) And exclude partition table:
Code:
dd if=/dev/sdc1 of=/dev/sda1 count=1 bs=446
Mount the source and destination drives:
Code:
mount -t ext4 /dev/sdc1 /mnt/source
mount -t ext2 /dev/sda1 /mnt/boot_target
mount -t ext4 /dev/sda2 /mnt/root_target
I suppose I can leave the swap partition on the target untouched. Copy the files from the source partition to the destination
Code:
cp -a /mnt/source/boot /mnt/boot_target
cp -a /mnt/source/ /mnt/root_target
then I assume I go to /mnt/root_target and delete the /boot directory, right? Change /etc/fstab to reflect the new partitions. I mount by label. Will my partition labels be intact after this? Do I have to make any changes to GRUB? Anything else?
I just finish setting Fedora 10 system including all the config that I like. I back up the image by using dd command.

I ran into an issue that was written up here on LQ and/or on other sites, the one dealing with an error similar to the following one: error trying to exec 'cc1plus': execvp: No such file or directoryThe solution seems is to make g++ and gcc versions consistent. I've since remedied that, but am slightly confused with my findings and concerned with my solution.
When I first looked in /usr/bin for all references to g++ and gcc, I saw that there were two version of gcc and one version of g++:
(Note the "??? ?? ????" as date for gcc. I've since made some changes, but this was essentially the set of gcc and g++ files that existed before I started.)
I'm told that the system I'm using is an "out of the box" installation, i.e. no modifications. As installed, gcc is the newer version and does not correspond to g++34:
Confusion and concern: When I use makefiles from software I've adopted, I run into the cc1plus problem eluded to above. The cc1plus error occurred because the makefiles expected there to be a command named "g++," so I created a symbolic link, pointing /usr/bin/g++ -> /usr/bin/g++34. And in doing so, g++ was not consistent with gcc. I've since fixed that, i.e. copied the gcc34 version to gcc and my software builds fine.
My question are:
1. Will copying the gcc34 version to gcc cause issues in the future, possibly related to upgrades and/or istallations of other packages that rely on "gcc"? Currently the files are as follows:
2. Were the g++ and gcc files in /usr/bin the "out of the box" versions?
3. How can I answer a question like this in the future, without posting to LQ, i.e. is there a reference to find this type of information?
Is there some sort of standards file path convention for installing softwares that I could follow through? For example, I just learnt how to build Nginx from source. But the default binary path set by nginx is "/usr/local/nginx/sbin". I have seen a couple of tutorials which they specify the location of the installed binary and it is very different from those usual default paths. Thus, got me thinking whether is there some form of file path convention that I should follow?Is there some kind of list which states where do those packages on Debian.org Repository usually installed to?

I moved my recording studio's site to it's own domain. [it used to be a series of pages on my A&R site.]
I now need to create a '301 Redirect' in my old site's directory to redirect surfers (who have my old url) to the new site...but more importantly...to retain my ranking w/ the major search engines...!
It cannot be done on a Windows server (which I'm on, w/ GoDaddy)...not an .htm redirect anyway, which I need. I've tried all the php, asp, etc. scripts...they don't work. [&...I don't think I really need windows features like php or asp...I code my site(s) in Dreamweaver as html pages.]
so...If I migrate my site(s) to a Linux server...
1) Will standard .wma streaming continue to work...? (i.e., a .wax file in the directory that points to the .wma).
2) Which type of server is FASTER for this task...(if any)...Linux or Windows...?
I have automated backups running on my ubuntu box using rsnapshot (rsync) basically following this tutorial. My concern is how to restore if everything is lost. Since it does not seem that I can backup the entire drive and that I have to choose individual folders and some like proc/ cause problems.
Currently in my rsnapshot.conf I have (see below). Is there a way to just clone the entire drive? Or should I not do this? Questions:
1, Can I backup in a way such that it is a clone of the drive so that it can be swapped with the current drive?
2, If not yes to clone, If I had a total drive failure would I install a basic ubuntu and then replace all the files with the backups?
3, Anything I might not know about that I should.
