  • How do I change the output line length from the "top" linux command running in batch mode

    - by Tom
    The following command is useful to capture the current processes that are taking up the most CPU in a file: top -c -b -n 1 > top.log The -c flag is particularly useful because it gives you the command line arguments of each process rather than just the process name. The problem is that each line of output is truncated to fit on the current terminal window. This is ok if you can have a wide terminal because you have a lot of the output but if your terminal is only 165 characters wide, you only get 165 characters of information per process and it is often not enough characters to show the full process command. This is a particular problem when the command is executed without a terminal, for example if you do it via a cron job. Does anyone know how to stop top truncating data or force top to display a certain number of characters per line? This is not urgent because there is an alternative method of getting the top 10 CPU using processes: ps -eo pcpu,pmem,user,args | sort -r -k1 | head -n 10

  • 100% height with fixed footer and embedded Google Map

    - by Carl
    I have a problem with a layout - it's not online anywhere, just local, but if you copy and paste the code below into an html page and run it locally you will see the same page I do. It's very nearly there. What I'm trying to achieve is a page with no scrollbars using up all available vertical space. Yes, I can set "overflow:hidden" on the container declaration and that helps, but it's not quite right. I want to actually have the google map surrounded with a 1em border. I have this on 3 sides but the 100% height declaration on the content div crashes the bottom border. If you don't realise the implications of a percentage-sized google map div, then the parent HAS to have a height declared for it to work. As the footer is absolute and outside of the flow, there is no "bottom" border to work to and the layout just doesn't work. The content div 100% height basically seems to take its size from the viewport and not the containing div. It's driving me mad... just can't seem to work out how to do this and I'd really appreciate some input. Start here: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head><title>Google map test</title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <style type="text/css"> html,body { margin:0; padding:0; height:100%; /* needed for container min-height */ background:fff; font-family:arial,sans-serif; font-size:small; color:#666; } h1 { font:1.5em georgia,serif; margin:0.5em 0; } h2 { font:1.25em georgia,serif; margin:0 0 0.5em; } div#container { position:relative; /* needed for footer positioning*/ margin:0 auto; /* center, not in IE5 */ width:960px; background:#fff; border-left:1px solid #ccc; border-right:1px solid #ccc; /*height:auto !important; real browsers */ height:100%; /* IE6: treaded as min-height*/ min-height:100%; /* real browsers */ } div#header { border-bottom:1px solid #ccc; border-left:1em solid #ccc; height:108px; position:relative; } div#header h1 { position:absolute; bottom: 0; left:0.5em; } div#header2 { border-bottom:1px solid #ccc; border-left:1em solid #999; height: 40px; position: relative; } div#header2 p { position:absolute; bottom: 0; left:0.5em; } div#headerInternal { border-bottom:1px solid #ccc; border-left:1em solid #cc3300; height: 40px; position: relative; } div#headerInternal p { position:absolute; bottom: 0; left:0.5em; } div#headerInternal2 { height: 40px; position: relative; } div#headerInternal2 p { position:absolute; bottom: 0; left:0.5em; } div#rightCol { float:right; width:29%; padding-bottom:5em; /* bottom padding for footer */ } div#content { float:left; width:70%; height:100%; /* fill that hole! */ border-right:1px solid #ccc; } div#content p { } div#footer { position:absolute; clear:both; width:100%; height:40px; bottom:0; /* stick to bottom */ background:#fff; border-top:1px solid #ccc; } div#footer p { padding:1em; margin:0; } .paddedContent { height:100%; margin: 1em; } </style> <script type="text/javascript"> function initialize() { var latlng = new google.maps.LatLng(52.397, 1.644); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } </script> </head> <body onload="initialize()"> <div id="container"> <div id="header"> <h1>Title here...</h1> </div> <div id="header2"> <p>Secondary menu...</p> </div> <div id="rightCol"> <div id="headerInternal2"> <p>Right Header</p> </div> <p class="paddedContent">This is the right column</p> </div> <div id="content"> <div id="headerInternal"> <p>Page Context Menu</p> </div> <div class="paddedContent"> <div id="map_canvas" style="width: 100%; height: 100%;"></div> </div> <div id="footer"> <p>This footer is absolutely positioned</p> </div> </div> </div> </body> </html>

  • getline() sets failbit and skips last line

    - by Thanatos
    I'm using std::getline() to enumerate through the lines in a file, and it's mostly working. It's left me curious however - std::getline() is skipping the very last line in my file, but only if it's blank. Using this minimal example: #include <iostream> #include <string> int main() { std::string line; while(std::getline(std::cin, line)) std::cout << "Line: “" << line << "”\n"; return 0; } If I feed it this: Line A Line B Line C I get those lines back at me. But this: Line A Line B Line C [* line is present but blank, ie, the file end is: "...B\nLine C\n" *] (I unfortunately can't have a blank line in SO's little code box thing...) So, first file has three lines ( ["Line A", "Line B", "Line C"] ), second file has four ( ["Line A", "Line B", "Line C", ""] ) This to me seems wrong - I have a four line file, and enumerating it with getline() leaves me with 3. What's really got me scratching my head is that this is exactly what the standard says it should do. (21.3.7.9) Even Python has similar behaviour (but it gives me the newlines too - C++ chops them off.) Is this some weird thing where C++ is expected lines to be terminated, and not separated by '\n', and I'm feeding it differently? Edit Clearly, I need to expand a bit here. I've met up with two philosophies of determining what a "line" in a file is: Lines are terminated by newlines - Dominant in systems such as Linux, and editors like vim. Possible to have a slightly "odd" file by not having a final '\n' (a "noeol" in vim). Impossible to have a blank line at the end of a file. Lines are separated by newlines - Dominant in just about every Windows editor I've ever come across. Every file is valid, and it's possible to have the last line be blank. Of course, YMMV as to what a newline is. I've always treated these as two completely different schools of thought. One earlier point I tried to make was to ask if the C++ standard was explicitly or merely implicitly following the first. (Curiously, where is Mac? terminated or separated?)

  • Why would this div have an unnecessarily large computed height?

    - by Mike Crittenden
    Link: http://www.fraynepainting.com/services The problem is that div#dditem_2 (the div with the "Take a look..." text) is getting a computed height of around 500px for no reason that I can find in the CSS, which is pushing the UL below it down really really far. I discovered that if you set display: none or position: absolute (or anything else that removes it from the flow of elements) on the sidebar, then the bottom UL moves up like it should, so it looks like maybe the UL is trying to clear the sidebar, but I can't figure out why that would be either. I've reproduced the problem in Firefox and Chrome so far. Any ideas?

  • CSS gurus, can I make my absolutely positioned child element force the main parent's height?

    - by alex
    This is kind of hard to explain. I have an absolutely positioned floating secondary content box. It works great in all occurrences. Except, when you submit a form and don't fill out the fields (see here, and push send). The box expands to show the errors, and underneath the footer there is a blank space. The best example I can give is to see it in action (link above). I've played with min-height and it didn't work too good. I'd also like to avoid expanding the footer with code in the event of form errors if I can help it. Should I ditch the absolute positioning? And try with margins? Is there any other way to get it to work?

  • How to get a Unicode-supporting font for Windows 7 command-line?

    - by Tim
    I've pointed the command-line to the right codepage (chcp 65001), but there's a lot of Unicode characters that Consolas and Lucida Console can't show. Specifically, I want the printable IPA characters to show up. It's not important to fix multi-codepoint glyphs, although it would be nice. How can I get such a font and install it for the command-line? Below is an example of some characters that can't be rendered.

  • How can I determine img width/height of dynamically loaded images in IE?

    - by Jens
    My markup is a simple div element with id 'load'. Using jQuery I then load a list of image elements into this div: $('#load').load('images.html', { }, function() { $(this).onImagesLoad({ selectorCallback: function() { ....do something.... } }); }); where images.html is a list like this: <img src='1.jpg' caption='img 1'> <img src='2.jpg' caption='img 2'> ... To ensure that all images are loaded completely, I use the onImagesLoad plugin. This, so far, works just fine on all browsers. However, on IE8 (and I assume other versions of IE also) when I then iterate over the img elements, I am unable to determine the width/height of the images loaded. The image.context.naturalWidth and naturalHeight attributes don't seem to work. How do I get a hold of the images' dimension? Thanks heaps :)

  • Making a row of divs all be the same height using CSS

    - by pavel
    I have a row of divs that must all be the same height, but I have no way of knowing what that height might be ahead of time (the content comes from an external source). I initially tried placing the divs in an enclosing div and floated them left. I then set their height to be "100%", but this had no perceptible effect. By setting the height on the enclosing div to a fixed-height I could then get the floated divs to expand, but only up to the fixed height of the container. When the content in one of the divs exceeded the fixed height, it spilled over; the floated divs refused to expand. I Googled this floated-divs-of-the-same-height problem and apparently there's no way to do it using CSS. So now I am trying to use a combination of relative and absolute positioning instead of floats. This is the CSS: <style type="text/css"> div.container { background: #ccc; position: relative; min-height: 10em; } div.a { background-color: #aaa; position: absolute; top: 0px; left: 0px; bottom: 0px; width: 40%; } div.b { background-color: #bbb; position: absolute; top: 0px; left: 41%; bottom: 0px; width: 40%; } </style> This is a simplified version of the HTML: <div class="container"> <div class="a">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit.</div> <div class="b">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit.</div> </div> This works, unless you change the min-height to something like 5em (demonstranting what happens when the content exceeds the minimum height), and you can see that while the text doesn't get cutoff, the divs still refuse to expand. Now I am at a lose. Is there any way to do this using CSS?

  • How to get PHP command line to work with PDO?

    - by Sabya
    I want to work with PDO, through PHP command line. It works perfect through the PHP web API, but not through the command line. But when I execute the command: php test.php, it says unknown class PDO. I think it has something to do with the thread-safety difference. Because, when I execute the above command, the following warnings come: - F:\shema\htdocs>php test.php PHP Warning: PHP Startup: soap: Unable to initialize module Module compiled with module API=20060613, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=1 These options need to match in Unknown on line 0 PHP Warning: PHP Startup: sockets: Unable to initialize module Module compiled with module API=20060613, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=1 These options need to match in Unknown on line 0 PHP Warning: PHP Startup: mysql: Unable to initialize module Module compiled with module API=20060613, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=1 These options need to match in Unknown on line 0 PHP Warning: PHP Startup: pdo_mysql: Unable to initialize module Module compiled with module API=20060613, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=1 These options need to match in Unknown on line 0 PHP Warning: PHP Startup: pdo_pgsql: Unable to initialize module Module compiled with module API=20060613, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=1 These options need to match in Unknown on line 0 PHP Fatal error: Class 'PDO' not found in F:\shema\htdocs\test.php on line 2 PHP version: 5.2.9-2, downloaded from here.

  • get value from css using document.getElementById().style.height javascript

    - by Jamex
    Hi, Please offer insight into this mystery. I am trying to get the height value from a div box by var high = document.getElementById("hintdiv").style.height; alert(high); I can get this value just fine if the attribute is contained within the div tag, but it returns a blank value if the attribute is defined in the css section. This is fine, it shows 100px as a value. The value can be accessed. <div id="hintdiv" style="height:100px; display: none;"> . . var high = document.getElementById("hintdiv").style.height; alert(high); This is not fine, it shows an empty alert screen. The value is practically 0. #hintdiv { height:100px display: none; } <div id="hintdiv"> . . var high = document.getElementById("hintdiv").style.height; alert(high); But I have no problem accessing/changing the "display:none" attribute whether it is in the tag or in the css section. The div box displays correctly by both attribute definition methods (inside the tag or in the css section). I also tried to access the value by other variations, but no luck document.getElementById("hintdiv").style.height.value ----> undefined document.getElementById("hintdiv").height ---->undefined document.getElementById("hintdiv").height.value ----> error, no execution Any solution? TIA.

  • Expandable or Auto-Resize TextBox Height

  • CSS variable height columns [migrated]

    I have created a website, www.unionfamilies.com. I have a header, a main section consisting of two columns, and a footer. Currently, I have specified heights for header, main, footer, etc. I would like to make the site so the header stays on top, the columns adjust to match the height of the longest column, and the footer stays at the bottom. Can someone help me with this? I am new to CSS, so please be patient. Thank you.

  • Command line solution for removing parts from a binary file?

    - by zsero
    I have a binary file and I would like to remove parts from. By removing I mean deleting those parts and thus making the file's size smaller. The parts would be between two ASCII strings. So, for example the file would look like this ........ start ABCD end ..... start EFGH end ..... start IJKL end ........... So in this file, I would like to search for strings "start" and "end" and remove the parts between them. The way I think I can do it is to lookup all the locations for "start" and "end" calculate ranges from that delete those parts Now I am using some GUI based Hex editor and I use the "Search All", "Select Range" and "Delete" commands, but I am sure it would be possible to solve it using some powerful command line hex/text editors. Do you know any solution for this problem which doesn't require using a GUI for looking up, copy & paste on clipboard, select range and delete commands but is just a few lines of command line? I am interested ini both Linux shell scripts or using some command line hex editors under Windows, or even Python scrips are welcome. Do you think it is possible to solve this problem just by a simple Regex replace? Are there any regex replace util which handles binary files well?

  • sprite animation system height recalculating has some issues

    - by Nicolas Martel
    Basically, the way it works is that it update the frame to show every let's say 24 ticks and every time the frame update, it recalculates the height and width of the new sprite to render so that my gravity logics and stuff works well. But the problem i am having now is a bit hard to explain in words only, therefore i will use this picture to assist me The picture So what i need basically is that if let's say i froze the sprite at the first frame, then unfreeze it and freeze it at the second frame, have the second frame's sprite (let's say it's a prone move) simply stand on the foothold without starting the gravity and when switching back, have the first sprite go back on the foothold like normal without being under the foothold. I had 2 ideas on doing this but I'm not sure it's the most efficient ways to do it so i wanna hear your inputs.

  • Javascript incapable of getting element's max-height via element.style.maxHeight

    - by Zane
    I am making a simple accordion menu in javascript. I'd like to be able to set the compact and expanded heights for the elements via the css max-height and min-height values. For some reason, when I try to retrieve the min-height and max-height of the elements in javascript for animation purposes, I get an empty string rather than, for instance, "500px" like it should. The max-height value is set in css, e.g. #id { min-height: 40px; max-height: 500px; } is all set up, but when I put a debugging mechanism in my javascript such as alert( item.style.minHeight ); it pops up an empty alert box. This happens in Firefox 3.6.2 and IE 8. Does anybody know why javascript refuses to be able to get an element's minHeight and maxHeight?

  • input box height issues

    - by Steven Xu
    I'm trying to set an input box with a specific internal height, and I'm running into issues: font-size: 12px; line-height: 12px; height: 12px; display: block; padding: 5px; Is a sample of what I put in inline styles or stylesheets. I would expect the input box value to be visible at full height, but the inner height of the input box ends up being really small, and it always seems to follow the form: actual inner height = css height - 2*border width - 2*padding Funny, because I swear I've done this before without issue. What am I missing?

  • jQuery UI resizable : auto height when using east handle alone

    - by z33m
    i have a jqueryui re-sizable div. I want only the width to be re-sizable and the height to remain auto, so that the div grows or shrinks with the content. If i set it to display only the east handle and use css height:auto, after resize the height also gets set even though only the width changed. I have to set the height to auto on resize event everytime like so: resize: function(event, ui) { $(this).css('height', 'auto'); } to prevent the height from being set. Is there a better way to prevent the height from getting set when only the east handle is used?
