General :: Add Number For Each Day From Log?
Jul 5, 2011
i have a log like:
Jul 4 23:19:02 Node-1 node-KPI: [INFO] KPI [proc.count = 11 files]
Jul 4 23:22:46 Node-1 node-KPI: [INFO] KPI [proc.count = 27 files]
Jul 4 23:37:49 Node-1 node-KPI: [INFO] KPI [proc.count = 27 files]
Jul 4 23:49:01 Node-1 node-KPI: [INFO] KPI [proc.count = 12 files]
[code]...
I would like to add up the numbers in the last column for each day and get that as the output. It could look like:
Jul 5 : 54
Jul 6 : 38
how can this be done with a bash script?

I need to get the max number from the name of a file
Formant of the file name:
[a-zA-Z]*_[0-9][0-9]_[A-Z][A-Z].log
Delimiter as underscore '_'
[code]....
known part in the above file name will be GA.log A give directory may or may not contain files in the above format or may contain file other then the above format if so then ignore it.
Eg:-
1) Directory=/tmp/log having below listed files
ant_01_EG.log ant_02_GA.log ant_04_EG.log cvs_01_EG.log cvs_02_GA.log cvs_04_EG.log master_01_GA.log master_03_EG.log master_04_GA.log
[code]....
output=> 06
2) Directory=/tmp/log no files
cmd=> ls *[0-9][0-9]_GA.log 2> /dev/null | awk -F_ '{ print $2}' | sort -nr | head -n1 | awk 'BEGIN { if ($1 >0 ) x=0; else x=1 } END {printf "%02.0f
", $1+1}'
output=> 01
if there are no files the output should be 01 and if file(s) found the output should be next highest number+1, In the above example it is 06 My cmd is bit lenghty. reduce my cmd and it should be in one line.

However could I set this to any value that I want?

I asked this question yesterday with Linux, but I realized I need to get it working in both Linux and OS X. Link to earlier question: Get folder with largest number at the end of the name in Linux. I have some folders r1, r2, r3, etc. and I want to get the name of the folder with the largest number at the end. How do I get the name? The ls -v solution looks promising, but I want to exclude all folders that don't follow the pattern r[0-9]*

I was wondering what is the maximum number of partition on an GPT-partitionned drive under Linux. The GPT partition table can contain up to 128 partitions, but the device nodes for /dev/sda? (as described here, block device of major number 8) only allow /dev/sda1 up to /dev/sda15. Does that means that there cannot be more that 15 partitions on a drive, even on a GPT-partitionned drive?

I'm currently trying to design a small, simple enough shell program for area codes. I have a list of area codes in a database, and I am trying to write a program that will have a user input an area code, and then have the program print out information that immediately follows that area code in my database. I assume I need to use a find or locate command, but I'm not sure if I should be searching for a string or the number itself. The number could possibly occur at some other point in the file, though the way I have the file set up it only occurs once at the newline.
what function I should use and how I should go about it? As is I only have the absolute bare-bones beginning of having an echo for the prompt to input an area-code, and the read once it's input. Without the find I'm not sure how much farther I can get. Also, would it make it easier if I added some character such as a ! to the end of the number at the newline to make it easier to search for? With a macro that would be easy enough to do.

im using CentOS 5.2 and cant change my default ssh port number. I have edited /etc/ssh/sshd_config to this
Code:
#$OpenBSD: ssh_config,v 1.21 2005/12/06 22:38:27 reyk Exp $
# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
[code]....
I have then restarted ssh by typing (as root) "sbin/service sshd restart" and it restarts fine but still is on 22 and not 222.

I created a group, and after adding the users into this group, they have a /home/worksharing that is shared
Code:
addgroup teamnight --gid 2578
So that everyone of the teamnight can read/write data of the /home/worksharing , how can this folder be forced, so that all from it e.g. subdirectories, directories, files,... will take the GID group number 2578 of teamnight?

Not only that but I need tons and tons of them generated, and I need it to be totally random each time.
Code:
matthew@mvm:/h/misc> cat a
#!/bin/bash
for i in {1..5}; do
echo $RANDOM
[Code]....
There you can see that it is the same number. It does that every time!! Grrr. The strange thing is each time I manually type [or copy & paste] it into the terminal, it gives random [not static, like I am getting from my script] results.
The reason I want this is because I am making a script where this line will randomly go up or down [depending on if the random number is 1 or 0].

I just found in kernel-2.6.35.3, in file arch/x86/kernel/irq.c:
unsigned int __irq_entry do_IRQ(struct pt_regs *regs)
{
struct pt_regs *old_regs = set_irq_regs(regs);
/* high bit used in ret_from_ code */
unsigned vector = ~regs->orig_ax;
[Code]...
Does any body know the relationship between the vector number and irq number?

Here's an example:
What do the numbers after so, such as in the last line, 1.1.0 mean?
My first guess was that they are version numbers, but:
So the 1.1.0 does not seem to have any connection to the version of the library, reported to be 2.4.46.

I'm trying to get an output of a file in numeric order. Basically I need the starting number and the ending number in sed this into anther file. The test2.lis file I'm just awk'ing for the first row and if its out of order put it in order so I can grab the first and last numbers. I'm sure I can do this all in an array. The first sed command gets rid of blank lines and outputs it to a file. Then I head and tail for the first and last number then I want to sed those numbers into a file that exsist.
[code]...
The error I get is:
sed: -e expression #1, char 24: unterminated `s' command.

I have a drive NTFS formatted drive mounted in Debian and a script set to make directories via a linux script and cron job. This was running flawlessly till recently, when I started getting 'mkdir: cannot create directory 'dirname': Operation not supported'.I have been unable to find any help with this issue online. I assume it is a NTFS mount issue. I know it isn't about file size, as the drive it 1TB.Here is my fstab for reference:Code:/dev/sdb1 /mnt/backupLocation ntfs-3g rw 0 0Do you know what the issue is here? Like I said, up until recently I have been able to create seeming unlimited directories here, but it now stops after about 7 - 10 directories have been created?

I would like to ask you if there is any maximum allowed number of files per folder in linux (without risking it to lose everything). I am using openuse 11.4 with latest kde (4.6?).
I am trying something fast and dirty and it might be that one folder will contain like 10^6 files.
Is there is anything I should be warned about that?
