been playing around making a server to play some games on running centos 5.5
what ive spent a while looking for (a few days) is a way to make a file which i will call startup this will contain some values
Code:
mod_directory="etpub"
port="27960"
log_name="console.log"
vm="0"
dedicated="2"
[Code].....
I don't understand the results of a simple performance test I ran using two basic scripts (running on a high end server):
perfVar.zsh :
#!/bin/zsh -f
MYVAR=`cat $1`
for i in {1..10}
[code]...
Performance test result:
> time ./perfVar.zsh BigTextFile > /dev/null
./perfVar.zsh FE > /dev/null 6.86s user 0.32s system 100% cpu 7.177 total
> time ./perfCat.zsh BigTextFile > /dev/null
./perfCat.zsh FE > /dev/null 0.01s user 0.10s system 91% cpu 0.118 total
I would have thought that accessing a VARIABLE was way faster than reading a FILE on the file system... Why this result ?Is there a way to optimize the perfCat.zsh script by reducing the number of accesses to the file system ?
I'm trying to prompt the user to enter Y or N in the middle of a while loop, but the read command is simply drawing in the next value.I'm reading from a simple file full of words (one per line)
Code:
while read line
do

so i cannot install anything because update-info-dir file is missing from /var/lib/dpkg/info/ .. I've searched for the last day and a half for a way to fix this, but nothing. can't even update dpkg because of this. so how do I bypass or fix this so I can install stuff (this is a fresh install of ubuntu 10.04 lts Lucid Lynx).

My requirement is that I wanted a shell script which should read the alert.log(oracle) and should send the alert to my email if any error encountered on daily basis. I have a script which does the same job but at the same time it creates a new alert.log whenever any error occur. But I don't want the new alert log I wanted to read the same alert log daily and if any new error come should alert as email.

I have a config file called hosts.cfg.
It contains entries like this:
Quote:
There are many more of these entries in the file, over 500, all in this same format: each host has a "define host" followed by 18 directives contained in squiggly brackets.
If I want to know all the hosts that are in the hostgroup called SERVER_GRP, I suppose I would need to read every hostgroups line (8th directive in squiggly brackets) that contains SERVER_GRP and output the corresponding host_name line (1st directive in squiggly brackets) from that entry.

I am very new to Linux and trying to learn the shell scripting. Just to know is there any client in linux which does the same task as FTPS on windows. FTPS on windows can read series of FTP command from a txt file and execute them. Is there any way to do that same task, i mean reading series of ftp commands from a txt file, on linux suing shell or perl (any module)?

I am new to shell script and to this form as well, I did try to search for a similar post like mine here, but could not find one.
Here is what I'm trying to do:
I am trying to grep server logs to find a specific string and then capture the time stamp and the value of that grep string in them. The log file prints out messages on per sec basis.
My script is able to grep the server logs for the entire period of my load runs and then outputted it to a .csv file too.
Unfortunately this .csv file is too large to extract it on my PC and to generate graphs as it exceeds the excel limit. I need some help on how to read this .csv file in a shell script and then take an average on per min basis before I can export it out on my desktop and generate graphs for analysis. example of the out in my .csv file:
I have a 7.2 GB file (VMWare virtual machine file) that I am trying to copy from its original location to the another folder OR to external hard drive...each time I try to do this, I always get the following error after the copying process reach 'exactly' 1.4 GB
Error reading from file input/output error
And I have to either Cancel or Skip
I've tried to split the files to smaller pieces but the idea didn't work as I still get the same error whenever I try to compress/ split or do any operation with this file. how I can copy this file?
I plugged in my USb drive into my computer yesterday and tried to delete a folder. I was unable to do so and got the following message
Cannot move file to trash, do you want to delete immediately? The file "my file" cannot be moved to the trash. Show Details Unable to create trashing info file: Read-only file system
So when I click on delete I get another error message:
Error while deleting.
There was an error deleting Case Study Database. Show Details Error removing file: Read-only file system
At this point I can only click on Skip, Skip All, or Cancel.
I have not changed anything on the stick recently so I dont know what is causing the problem.
I want to create a logon script (or somesuch) that creates a file (if it doesn't already exist) and checks the file for some info otherwise. If it finds a given trigger in that file, it logs into a local database and does some operations.
Now my problem isn't with creating that file or even getting it to function as a logon script -- it's with permissions. After the logon script creates the file, I want that user to have read access on it ONLY. Further, I don't want to give the user any kind of root access so that they could do the database operations in question or chown/chmod the file.
What's the best practice here? I'm noticing that whenever the script runs (in .bashrc right now) the script runs with the current user's permissions. Ideally, I'd like to make it so the login script can run at a higher level of permissions, (higher than the user has). Is this even possible? What's the best way to do this?

I am using a backup system with cron + tar. Since the server is very busy, I get often the cron-email: "The file XYZ has changed while reading". This message is a bit annoying and I see it as critical point in my backup system. I believe that this file is then not in my backup. (Is that correct?) Let's imagine the hard disk dies and I have to recover the system and my personal data, and in the night the mysql-table XYZ was not in the backup, because it was in read-usage. I would then have lost this table forever. Is there any way to tell TAR, that it should force the file to be included (if in read-usage, then wait 2 seconds and try again)?
View 9 Replies View RelatedI recently set up a server in my house using Apache 2 running off Ubuntu 10.10 Netbook edition (no, the computer is a desktop). I tried running the website on a few computers in house and all the images and scripts seem to load fine but it is unable to read from the data.xml file through javascript. This leaves all of the web pages empty because all of the content is parsed from the xml file through javascript. I tried debugging with google chrome and after running this code to load the xml file:
if (window.XMLHttpRequest) {
// For IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
}
[Code].....
the xmlhttp.responseXML is null and the script crashes. Could this be a permission issue? I tried setting the data.xml file to read-write permission for any user but that didn't work.
Running 10.04 64bit. Installed the latest Gnucash from repositories. Using Quicken 2003 and exported an account to a qif file. When trying to import to Gnucash the error "A bug was detected while reading the QIF file." displays. This, at least is more than I was able to do previously (prior to 10.04 and several earlier versions of Gnucash running in 8.04 through 9.10). Before it would cause Gnucash to crash and shutdown. I select a specific account with categories from Quicken to export. I can import to KMymoney and use it but that program is not compatible with the wife and does not do reconciliation reports by default.

I have a binary file, which I need to process using my C++ application. Only thing I know is first chunk of the file is long, second chunk is int, third chunk is char etc... The binary file actually contains something like below. (which is represented in hex base).
D7 07 00 00 00 00 00 00 37 18 00 00 DE 07 ............ so on.....
I need to procees the file in the following way.
* I know the first data segment in my file is long. So it takes 4 bytes.
* so I need to read the first four bytes. That is D7 07 00 00.
* Then I need to reverse this as 00 00 07 D7.
* Finally I need to get the decimal value of above hexa decimal line. ( 00 00 07 D7)
* i.e. 00 00 07 D7 (in hex) = 7D7 (in hex- after removing leading 0 s) = 2007 (in decimal)
Like wise I need to process the whole file.
I know that this is a really simple thing to do but I just can't figure it out. How do I read a text file into an array in C++?
View 3 Replies View RelatedI have two files of data with different numbers of columns and rows. I want to read this two files in two arrays and then compare for example the second column of first data file with the third column of the other text file and if the difference between of two numbers is less than a threshold then the program print the information in the rows which fulfill this condition in the third text file. I have written below program but the problem is that it does not go through all rows of second file.
declare -a a
declare -a b
r=` awk '{n++} END {print n}' second.txt `
echo $r
awk '

Actually I have two data files one of them contains 44406 and the other one has 12066 rows and I want to check whether the difference between the components of two specific columns is less than a threshod but I have simplified it here. I had written this code and then I have realized that this code just goes through the number of rows as the same as the first.txt file and ignores the rest. I could not find the problem yet.
