In the file /var/log/kern.log, I see kernel logs in the following format,
Oct 6 11:18:30 machine kernel: [212.443755] Some logs...
What are the numbers in the bracket [212.443755] stands for?
On startup, I get messages which look like this:
[Code]...
What do the numbers in brackets mean? (I tried looking, but I don't know how to start to search for the answer to that without being too vague). I've noticed they're nearly always progressive (increasing). Do they just refer to the event number? And in my log file viewer, why is there a dmesg and a dmesg.0?
I came across this reult of the type command (hashed) in another post. (see below).
Code:
fraespappp8:/data/apps > type topic_file_publish.sh
topic_file_publish.sh is hashed (/data/apps/pnbgstk/publication/topic_file_publish.sh)
This (result = hashed) is new to me.
I wonder which kernel/distro/shell it is from.
I've been playing around with trying to assemble a bare-bones Linux system on a disk.img file through a loop device. I compiled the most recent stable kernel and then copied it onto the root partition in the image. When I try to boot up into the image using qemu, grub gives me this:
Code:
Booting 'tiny'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinux
Error 13: Invalid or unsupported executable format
Press any key to continue... I am confused because I compiled the kernel with 'make bzImage', and the architecture hasn't changed (qemu on the same machine used to build the kernel). So it should be bzImage format. Is that what this Error 13 means, or could it means something else is wrong...?
am writing a small search program for my class. I have decided to use indexing for my program. Ive researched online about indexing and how search engines do it. If im gonno do that I need to create inverted files to associate files to numbers ( numbers being the index of my paths ) . Now I was wondering what would be the best way to create an inverted file ? I was going to create sql tables using mysql api in C but then again there is no array data type or vectors to store few numbers in a single column in mysql and it is not advised to use Enum or SET

The way I organize all my files into their folders, they add up quickly. I like having a quick way to keep more frequently accessed folders at the top of the list in explorer. In windows, folder "[zippidy do da]" would appear above folder "aardvark" because of the brackets, but Ubuntu's file browser ignores the brackets, making my old method ineffective. I could put a zero in front of such folders
View 5 Replies View RelatedIve been trying to PXE boot a XEN kernel image in gzip format, and I was getting Invalid or corrupt kernel format error. Ive seen that other kernel images having a file type of Linux kernel x86 boot executable RO-rootFS are bootable. (both are bootable using grub anyhow).
Is there any way to convert the b/n the formats, or any other solution?
I was booting a Virtualbox instance, again I guess that shouldn't matter because pxelinux loads from tftp properly, but it doesn't even proceed to load the kernel. I think the issue here is with the image format itself rather than what it contains, or where it runs.

View 12 Replies View Related I'm working with a rather large file of data taking from a tracking program on my phone, and trying to pull only the longitude and latitude from it. Any given line in the data looks more or less like this:

I've run it through this command:
grep skyhook log-2010-05-10_18-17-28.json | cut -d"," -f1,10
to get this:

Which is a lot nicer, but I would prefer not to have to hand remove the non-number characters by hand since there are thousands of data points. what I could do to get it to just be longitude and latitude in 'number number' format?

Firstly I would like to say that Linux is very cool, especially the CLI. I have been trying to learn how to do some things in Fedora after being told Fedora was a good distro to get my feet wet. I have run into some issues and cant seem to find any answers. What Linux utility can be configured to automatically save the current logs?
How does your Fedora get an IP number? What IP numbers has your Fedora been assigned since it was installed (based on the logs you have)? What command did you run to determine the IP numbers? What command would you run to determine the number of times a user successfully used "su"? What command would you run to determine the number of times a user unsuccessfully used "su"? Having some issues with the file system as your Fedora boots up.
I have a weird problem with one of my servers (normal PC hardware). I was connected remotely using Putty, doing some stuff, and all of the sudden some commands, like "ls" stopped working, giving a "file or command not found" type of message. I restarted the ssh session, only to find out I couldn't log on any more (access denied). When I got home and rebooted the system, I was greeted with this:Booting 'CentOS (2.6.18-194.el5xen)'root (hd0,0)Filesystem type is ext2fs, partition type 0x83kernel /boot/xen.gz-2.6. 18-194.el5Error 15: File not foundPress any key to continue...Then I searched about this, found out that the files in /boot/grub/menu.lst did not exist at the specified location (/boot/xen.gz-2.6. 18-194.el5). Somehow I managed to find them in another place, copied them in place, and now I get:Error 13: Invalid or unsupported executable format

My second problem is that I am trying to get list of files in a directory that were changed less than 10 hours ago, using grep, while leaving out directories. I am completely stuck with the second problem.

Create the file ~/license_counts, which tables the number of occurrences of packages which are licensed under a given license, for the top 5 most commonly used licenses, sorted in numerically descending order. If performed correctly, your file should be formatted similarly to the following. (Do not be concerned if the actual counts or license names are different. Also, you might notice logically similar licenses, such as LGPL/GPL and GPL/LGPL. Do not make any attempt to combine them into a single entry.)
The resulted format:

I am using RHEL 5. In my Linux Box I have two Lan cards (eth0 and eth1). "eth0" is connected with network 192.168.10.0 and "eth1" is connected with network 192.168.11.0. Both Network are inter connected via routing. Now I want a situation where, I want to dedicatedly assign some port numbers against a lan card. Like eth0 will be assigned for ssh (22) and eth1 is assigned for telnet (23). So that, when a user connect to 22 port then he/she is connected to the server through eth0 , and when a user connect 23 port then he/she is connected to the server through eth1. Is it possible to do using iptables or other?
View 2 Replies View RelatedIs there a command to return a recursive listing of sub-directories and the number of files in them? I have found plenty of ways to give me the total number of files in a directory structure, but none that gives a list of the sub-directories with the number of files in them. "du" gives me a listing of directories with their sizes, but I couldn't find an option (or any other way) to give me the number of files as well. Ideally, I'd like to get list with "Size" "Files" "Dir name" - And the order of the columns doesn't matter. Is there a "simple" command line solution or do I need a shell script for that?
