  • Read a file from line X to line Y ?

    - by thedp
    Hello, Is there a way to read a file in PHP5 from line X to line Y into a string, without reading the entire file. I would like to return huge files (10,000+ lines) using ajax requests. Each request will provide the client with additional lines. And due to the fact that the file can reach large sizes, I would like to avoid reading it whole over and over again. Thank you.

  • Getting n-th line of text output

    - by syker
    I have a script that generates two lines as output each time. I'm really just interested in the second line. Moreover I'm only interested in the text that appears between a pair of #'s on the second line. Additionally, between the hashes, another delimiter is used: ^A. It would be great if I can also break apart each part of text that is ^A-delimited (Note that ^A is SOH special character and can be typed by using Ctrl-A)

  • xargs command works on ubuntu, but not mac

    - by Corey Hart
    I have the following line of code that I use to update my personal date variable in my projects to todays current date. This line works in Ubuntu's terminal, but the Mac terminal seems to be far behind. Unfortunately, I copied this snippet from some site, so I'm not sure how it exactly works. Suggestions? grep -ilr --exclude=revar.sh --exclude=README.md "[DATE]" * | grep -v .git | xargs -i@ sed -i "s/\[DATE\]/${today}/g" @

  • Write file at a specific value and line

    - by user2828891
    I want to write data at a specified value in a text file from a text box. Here is a example: item_begin etcitem 3344 item_type=etcitem is first line and item_begin weapon 3343 item_type=weapon is second. Well i want to replace item_type=weapon at second line with item_type=armor. Here is code so far: var data2 = File.WriteAllLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); But returns error at WriteAllLines. Here is the readline part code: var data = File.ReadLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); //call values textitem_type.Text = data["item_type"]; And want to write the same value I change on textitem_type.Text after read. I used this to reaplace but replaces all values with same name from line and returns me in text only 1 line. Code: private void button2_Click(object sender, EventArgs e) { var data = File .ReadLines("itemdata.txt") .Where(x => x.Contains(itemSrchtxt.Text)) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); StreamReader reader = new StreamReader(Directory.GetCurrentDirectory() + @"\itemdata.txt"); string content = reader.ReadLine(); reader.Close(); content = Regex.Replace(content, data["item_type"], textitem_type.Text); StreamWriter write = new StreamWriter(Directory.GetCurrentDirectory() + @"\itemdata.txt"); write.WriteLine(content); write.Close(); }

  • Displaying data points in Flex Line chart...

    - by dmose
    I have a flex line chart. Instead of the default behavior of having to hover over parts of the line to see the data points, is there a way to change the rendering of each point and have them always displayed? (almost like a connect the dots type view).

  • How to find multiple words on the same line in Notepad++

    - by Mike
    I have a 4MB log file from the Windows XP firewall which I'm trying to find lines that have both DROP and an IP and a port number. My regex-fu is weak and I'm assuming this is the reason I'm struggling. The words "DROP", "10.1.1.1" (for example) and "8801" need to be found on the same line and may be spread across the line and separated by one or more other words. Any help (or suggestions of another method to do this) are much appreciated.

  • Can this be done in 1 line? [PHP]

    - by Angelo
    Can this be done in 1 line with PHP? Would be awesome if it could: $out = array("foo","bar"); echo $out[0]; Something such as: echo array("foo","bar")[0]; Unfortunately that's not possible. Would it be possible like this? So I can do this for example in 1 line: echo array(rand(1,100), rand(1000,2000))[rand(0,1)];

  • How do the environments of a standard Terminal command-line and a bash script differ?

    - by fred.bear
    I know there is something different about the environment of the Terminal command-line and the environment in a bash script, but I don't know what that difference is... Here is the example which finally led me to ask this quesiton; it may flush out some of the differences. I am trying to strip leading '0's from a number, with this command. var="000123"; var="${var##+(0)}" ; echo $var When I run this command from the Terminal's command-line, I get: 123 However, when I run it from within a script, it doesn't work; I get: 000123 I'm using Ubuntu 10.04, and tried all the following with the sam results: GNOME Terminal 2.30.2 Konsole 2.4.5 #!/bin/bash #!/bin/sh What is causing this difference? Even if some upgrade will make it work in scripts... I am trying to find out the what and why, so in future, I'll know what to look out for .

  • Disabling shutdown command for all users, even root - consequences?

    - by Rich
    I would like to disable the shutdown command for all users, even root, on an Ubuntu Server installation. The reason I want to do this is to ensure that I don't get into the habit of shutting down the machine in this way, as I SSH into a lot of production machines at the same time as this one, and I don't want to accidentally shutdown one of the other machines by typing the command into the wrong window. The server I want do disable shutdown on only runs inside VirtualBox on my Windows desktop, and I only use it for local testing so it is not a problem if I can't shut it down from the command line. I have already mitigated the problem a bit by ensuring I have a different password on the VirtualBox image, but obviously if I am within the sudo 'window' on one of the production machines, I could still accidentally shut it down. My questions are: How do I disable the shutdown command? If I do disable the shutdown command, are there any consequences that I should be made aware of? Most specifically, will it disable support for ACPI shutdown that is the equivalent of pressing the power button on a physical machine? Could it affect other generic applications? For information, I just use this VirtualBox image for trying out shell scripts, running Tomcat and Java, and that kind of thing.
