View 2 RepliesI am looking for an easy way to convert any given maze.txt of any size to a internal array of strings(dynamically allocated). Important is that dimensions of the maze (row, col) shouldn't be written by the user instead they have to be somehow read from the file. This is not my homework assignment! It is a small part of a project that i never dealt with. I never read files to C string.... I made it for specific maze dimensions, but want it to work with any given .txt file.

View 1 Replies View RelatedI've a popular vbulletin forum (10k max in vbulletin stats 'whos online') runnin in two servers like this:
1) Web server running vBulletin.
Dual Intel E5620 @ 2.40GHz (shows 16 cpus)
12 GB RAM
2 x 500 GB SATA (one for system/web and other for backups)
CentOS 5.6 64 bit
Apache/2.2.17
PHP 5.2.16
2) MySQL 5.server
Dual Intel E5620 @ 2.40GHz (shows 16 cpus)
16 GB RAM
2 x 500 GB SATA (one for system/web and other for backups)
CentOS 5.6 64 bit
MySQL 5.0.77
Web server connects to MySQL using private LAN.
Web-php server works with xcache as recommended by vBulletin.
Image/avatars and other static files (css, js, etc) are on a CDN
MySQL server uses Memcached for caching common queries.
The problem I'm facing, is from time to time (let's say one or two times a week) the Web server goes into read only mode... then the server has to be rebooted in order to get online normally and be able to work. From the logs I've seen this:
Code:
This is a new server, and in the old server the 'read only mode' issue happened very often too... so I guess it's not a HD issue.. it's just the HD have a heavy I/O usage. What do you think?
I am thinking about this solutions to improve the webserver performance:
1) 75% of the vbulletin users are anonymous users, so I've been thinking about using Cloudflare as a cache for all that traffic, that would reduce the php-webserver process a lot.
2) Using an external email server is a good option I guess... as right now the webservers also handles the email notifications for all the vbulletin users and it is constantly sending email everywhere. So, email will be stopped to gain server performance.
3) Mounting partitions with 'noatime' at /etc/fstab seems to improve I/O performance.
Is there an app I can put on my website hosting server that will do the following:

I have a csv file in this format:
Code:
1,characterswithnospace
2,same
4545,characters
I want to extract only the strings after the comma,
here's my newbie question - I want to change the following string in text files
Code:
E:MP3
with the following string using sed:
[code]....
I have two text files in the form:1 ItemA [value]2 ItemB [value]3 ItemC [value]Some of these items are common for both files, while others are missing from either one or the other.I want to compare the values for each common item in the two lists, but don't know how. I have a vague idea that probably grep might be useful, but I don't know how to use it for this purpose.So, to sum it up, what I would like to do is to take to text files containing lists and merge their common items into a third file in the form:
1 ItemA [value_from_list1] [value_from_list2]
2 ItemB [value_from_list1] [value_from_list2]
3 ItemC [value_from_list1] [value_from_list2]

I wrote this small program that will truncate a string that's entered in by the user.An example of its usage:if the user enters in a string say "abcdefghijklmnopqrstuvwxyz" the program will only take the first 9 characters and truncate the rest so that the user can be prompted for a second string and not be worried about remaining characters left in the stream.Now this program works O.K. but I would like to find something in C that has this functionality build into it...Does anyone know of any function that will accomplish this.

I'm not overly great with bash scripting. I do more batch file stuff for Windows than anything else but I'm trying to branch out a bit. (Frankly, I'd love to do this in Ruby but I'm not there yet...) Maybe I'm not using the correct terminology and that's why my searches are coming up useless...
Anyway, I have a script that does some work with HandBrake. Although it deals with HandBrake, I think the issue is not with HandBrake itself. The issue: I had a simpler script which worked fine but it would give me an MP4 with a file name of: Some Movie Name.iso.mp4 and it would still play but I wanted to get rid of the .iso in the file name. I also wanted to drop it into another directory during the encoding. That's why you see a $source & a $destination variable.

Code:
#!/bin/bash
source=/media/data/movies
destination=/media/data/movies/mp4s

I use udhcp with some of my minimal installs. I've messed around with the code a bit when it wasn't working correctly - a few years ago. I will find time - I hope soonish - to figure out how to do a few other things with it.
For now though, I'm using this string to grab my ip after startup
Code: Select allsu -c 'ifconfig eth0&&ifdown -a&&ifup lo&&ifup eth0'&&/sbin/ifconfig eth0
I realize I could substitute ifup -a but I'm more interested in figuring out how to make ifup wait for the ip to become available if it is not available yet.
Never mind that one, just typing out the question answered it for me, when I find it in the scripting man ' ; : " & =
Or if there are any other suggestions for better construction of the string.
I have a PHP script written that is checking a string to see if it contains a link in it (i.e. a URL). I have the following if statement, that uses 3 possible regular expressions to determine if there is a link or not.

// links are denoted by strings that:
// - contain http://
// - contain www.*.*

I'm not convinced yet that writing a shell script to do this is the best course of action. If someone is capable of doing this with a Perl or a Python script that's fine too. If you want to make it super high performance and write it in assembly
I am using sed to process an ascii tcpdump file whereby each packet is processed into a line with the same number of columns and useful information is pulled out like the time, packet type, length, and also IP addresses, payload type and port numbers where appropriate. The time is already changed to seconds, followed by the protocol over ethernet, such as IP, IP6, ARP etc. and I can change anything it detects as IP, IP6 and ARP into some other string, pulling out necessary information depending on the protocol and payload.The beginning part of the search for IP starts with the sed search /([0-9][0-9]*.[0-9][0-9]*)[ ]IP[ ,] ... /, where time is in seconds and ellipses means more stuff, and likewise for IP6 and ARP.But how do I process the lines that are NOT IP, IP6 or ARP? (Specifically NOT /IP[ ,]/, /IP6[ ,]/ or /ARP[ ,]/.) So that I can format them into a string with the same number of columns.

Is there a faster way to search for a file containing a given string than using grep -re "string" /
This takes a long time to search through the entire system, so I was wondering if there is a faster way. I don't know the name of the file, just that it will contain a given string.
Let me know unix commands to implement set operations on strings.
