  • BASH Scripting: Check If running with sudo/superuser, if not, dont run, return error

    - by EvilPhoenix
    This is something I've been curious about. I make a lot of small bash scripts (.sh files) to do tasks that I routinely do. Some of those tasks require everything to be ran as superuser. I've been curious: Is it possible to, within the BASH script prior to everything being run, check if the script is being run as superuser, and if not, print a message saying You must be superuser to use this script, then subsequently terminate the script itself. The other side of that is I'd like to have the script run when the user is superuser, and not generate the error. Any ideas on coding (if statements, etc.) on how to execute the aforementioned?

    Whenever I try and uncompress the tar file, I get this: tar (child): nakasi-jro03d-factory-e102ba72.tg: Cannot open: No such file or directory tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now I'm fairly new to Ubuntu. So I'm pretty sure that's my fault. So I just compress it manually using the GUI. But when I try to flash it, I get sudo: ./flash-all.sh: command not found Please help.

  • Return to the old C days.

    - by RPK
    Long back I used to program on C and than VB exploitation changed the career path. After VB came the .NET that proved to be a HoneyPot of Microsoft for old VB programmers and frustrated programmers of other hard to learn languages. The label on this HoneyPot was: "Getting things done." I now want to contribute to the Linux and other GNU projects. I feel whatever programming language you learn today, but if programming is your bread-and-butter, you must remain in touch with C. Many things have changed now. From the old Turbo-C for DOS to the present ...? Please advise me how to get back on the C track again. Reading again whole thing, chapter-by-chapter is not possible now, but I can learn by writing small utilities type of things, but sure GUI based. And yes, I hope, learning is going to be easy now with so many live forums and active community spots like StackOverflow etc.

  • Enable Configurator for Return Orders

    - by ChristineS-Oracle
    With release 12.2.4 for non-referenced RMAs, Order Management will allow you to configure the model from Sales Order / Quick Sales Order windows. This is only allowable when profile  OM: Enable Configuration UI for RMA is set to Yes.  All selected options must be returnable, as well as all included items. Order Management explodes included items and creates options and option classes in a way similar to outbound orders. The application creates all selected components with same line number but different option/component number.  Additionally, the application does not allow re-configuration and/or deletion of any line if any line in the same configuration is received, fulfilled, closed, cancelled, or split. For additional information refer to the Oracle Order Management Release Notes for Release 12.2.4 (Doc ID 1906521.1).

  • How to return older Thunderbird version?

    - by Holger
    today at startup my Tb (not precisely sure what version it was) asked if it should check compatibility of the lightning calendar addon. That is to say it displayed in a list windows the only item: lightning and said it was not compatible. Choices were "check" or "don't" check compatibility. I clicked on check and after nothing happened for several minutes on "cancel". So, now my Tb is upgraded to 15.0 and Lightning isn't there anymore. It never asked me to upgrade anyway and I urgently need my calendar now. Any suggestions warmly welcome! Holger

  • The Return of Oracle Wikis: Bigger and Better

    - by oracletechnet
    The Oracle Wikis are back - this time, with Oracle SSO on top and powered by Atlassian's Confluence technology. These wikis offer quite a bit more functionality than the old platform. For example, wikis are now associated with groups/spaces, as opposed to an open free-for-all, and space owners have curative responsibility (for approving new members, moderating comments, and so on). All in all we're confident that you will be pleased with the experience. Of course, we'll be on the hunt for bugs/issues for a while, and if you find any yourself we encourage you to report them here.

  • Assignments in mock return values

    - by zerkms
    (I will show examples using php and phpunit but this may be applied to any programming language) The case: let's say we have a method A::foo that delegates some work to class M and returns the value as-is. Which of these solutions would you choose: $mock = $this->getMock('M'); $mock->expects($this->once()) ->method('bar') ->will($this->returnValue('baz')); $obj = new A($mock); $this->assertEquals('baz', $obj->foo()); or $mock = $this->getMock('M'); $mock->expects($this->once()) ->method('bar') ->will($this->returnValue($result = 'baz')); $obj = new A($mock); $this->assertEquals($result, $obj->foo()); or $result = 'baz'; $mock = $this->getMock('M'); $mock->expects($this->once()) ->method('bar') ->will($this->returnValue($result)); $obj = new A($mock); $this->assertEquals($result, $obj->foo()); Personally I always follow the 2nd solution, but just 10 minutes ago I had a conversation with couple of developers who said that it is "too tricky" and chose 3rd or 1st. So what would you usually do? And do you have any conventions to follow in such cases?

  • how to have 'find' not return the current directory

    - by Pinpin
    I'm currently trying to find (and copy) all files and folder structure matching a specific pattern, in a specified directory and I'm so nearly there! Specifically, I want to recursively copy all folders not begining with a '_' character from a specified path. find /source/path/with/directories -maxdepth 1 -type d ! -name _\* -exec cp -R {} /destination/path \; In the /source/path/with/directories/ path are machine-specific directories beginning with '_' and others, and I'm only interested in copying the others. For a reason beyond me, the find command returns the /source/path/with/directories/ directory, and therefore copies its content, directories begining with '_' included. Anyone have a hint as to why that is? Thanks, Pascal

  • return to middle click copy and paste ubuntu 13.10

    - by user206999
    Recent update to 13.10 left the middle mouse button turning sound on and off!! How do I get back to being able to copy and paste? Select the text then paste with the middle Wheel mouse button. This is a feature I used to use a lot and I find extremely quick and useful. I know I can use ctrl c, ctrl v, and right click select copy, select paste but this is clunky compared to just being able to click the middle wheel button. Is there a settings menu option to gain correct operation of the middle wheel button?

  • Boosting That Return Rate

    I've noticed something about most beginner Internet marketers. They get really excited when they get traffic - even if that traffic doesn't convert to anything in the way of sales or proceeds. They're over the moon about the chance to make a profit. That's where they go wrong, unfortunately. It's fun to be excited at first, but after a week or so, reality really needs to set in and you need to start making decisions based on factors like conversions and ROI rather than raw traffic.

  • ERROR_PROCEDURE Does Not Return a Schema Name

    "A recent blog entry I read reminded me again that I wanted to rant about an issue in SQL Server for quite some time now. SQL Server 2005 introduced the separation between user and schema. Though schemata already existed before SQL Server 2005, they really became usable with this version, imho. At the same time TRY...CATCH was a new way for structured error handling introduced. And so it finally became possible…" NEW! SQL Monitor 2.0Monitor SQL Server Central's servers withRed Gate's new SQL Monitor.No installation required. Find out more.

  • WCF- "The underlying connection was closed: The connection was closed unexpectedly"

    - by SumGuy
    Hi there. I'm recieving that wonderfuly ambiguous error message when using one of my webmethods on my WCF webservice. As that error message doesn't provide any explanation whatsoever allow me to post my theory. I believe it may have something to do with the return type I'm using I have a Types DLL which is refrenced in both the webservice and the client. In this DLL is the base class ExceptionMessages. There is a child of this class called DrawingExcepions. Here is some code: public class ExceptionMessages { public object[] ReturnValue { get; set; } } public class DrawingExceptions : ExceptionMessages { private List<DrawingException> des = new List<DrawingException>(); } public class DrawingException { public Exception ExceptionMsg { get; set; } public List<object> Errors { get; set; } } The using code: [OperationContract] ExceptionMessages createNewBom(Bom bom, DrawingFiles dfs); public ExceptionMessages createNewBOM(Bom bom, DrawingFiles dfs) { return insertAssembly(bom, dfs); } public DrawingExceptions insertAssembly(Bom bom, DrawingFiles dfs) { DrawingExceptions des = new DrawingExceptions(); foreach (DrawingFile d in dfs.drawingFiles) { DrawingException temp = insertNewDrawing(bom, d); if (temp != null) des.addDrawingException(temp); if (d.Child != null) des.addDrawingException(insertAssembly(bom, d.Child)); } return des; } Returns to: ExceptionMessages ems = client.createNewBom(bom, currentDFS); if (ems is DrawingExceptions) { } Basically the return type from the webmethod is ExceptionMessages however I would usually be sending the child class back instead. My only idea is that it's the child that's causing the error but as far as I've read, this should have no effect. Has anyone got any ideas what could be going wrong here? If any more info is required, just ask :) Thanks.

  • Memory leak when returning object

    - by Yakattak
    I have this memory leak that has been very stubborn for the past week or so. I have a class method I use in a class called "ArchiveManager" that will unarchive a specific .dat file for me, and return an array with it's contents. Here is the method: +(NSMutableArray *)unarchiveCustomObject { NSMutableArray *array = [NSMutableArray arrayWithArray:[NSKeyedUnarchiver unarchiveObjectWithFile:/* Archive Path */]]; return array; } I understand I don't have ownership of it at this point, and I return it. CustomObject *myObject = [[ArchiveManager unarchiveCustomObject] objectAtIndex:0]; Then, later when I unarchive it in a view controller to be used (I don't even create an array of it, nor do I make a pointer to it, I just reference it to get something out of the array returned by unarchiveCustomIbject (objectAtIndex). This is where Instruments is calling a memory leak, yet I don't see how this can leak! Any ideas? Thanks in advance. Edit: CustomObject initWithCoder added: -(id)initWithCoder:(NSCoder *)aDecoder { if (self = [super init]) { self.string1 = [aDecoder decodeObjectForKey:kString1]; self.string2 = [aDecoder decodeObjectForKey:kString2]; self.string3 = [aDecoder decodeObjectForKey:kString3]; UIImage *picture = [[UIImage alloc] initWithData:[aDecoder decodeObjectForKey:kPicture]]; self.picture = picture; self.array = [aDecoder decodeObjectForKey:kArray]; [picture release]; } return self; }

  • Should I use early returns in C#?

    - by Bobby
    I've learned Visual Basic and was always taught to keep the flow of the program without interruptions, like Goto, Exit and Return. Using nested ifs instead of one return statement seems very natural to me. Now that I'm partly migrating towards C#, I wonder what the best practice is for C-like languages. I've been working on a C# project for some time, and of course discover more code of ExampleB and it's hurting my mind somehow. But what is the best practice for this, what is more often used and are there any reasons against one of the styles? public void ExampleA() { if (a != b) { if (a != c) { bool foundIt; for (int i = 0; i < d.Count && !foundIt; i++) { if (element == f) foundIt = true; } } } } public void ExampleB() { if (a == b) return; if (a == c) return; foreach (object element in d) { if (element == f) break; } }

  • Spring MVC return ajax response using Jackson

    - by anshumn
    I have a scenario where I am filling a dropdown box in JSP through AJAX response from the server. In the controller, I am retuning a Collection of Product objects and have annotated the return type with @ResponseBody. Controller - @RequestMapping(value="/getServicesForMarket", method = RequestMethod.GET) public @ResponseBody Collection<Product> getServices(@RequestParam(value="marketId", required=true) int marketId) { Collection<Product> products = marketService.getProducts(marketId); return products; } And Product is @Entity @Table(name = "PRODUCT") public class Product implements Serializable { private static final long serialVersionUID = 1L; private int id; private Market market; private Service service; private int price; @Id @GeneratedValue(strategy = GenerationType.AUTO) public int getId() { return id; } public void setId(int id) { this.id = id; } @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name = "MARKET_ID") public Market getMarket() { return market; } public void setMarket(Market market) { this.market = market; } @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name = "SERVICE_ID") public Service getService() { return service; } public void setService(Service service) { this.service = service; } @Column(name = "PRICE") public int getPrice() { return price; } public void setPrice(int price) { this.price = price; } } Service is @Entity @Table(name="SERVICE") public class Service implements Serializable { /** * */ private static final long serialVersionUID = 1L; private int id; private String name; private String description; @Id @GeneratedValue @Column(name="ID") public int getId() { return id; } public void setId(int id) { this.id = id; } @Column(name="NAME") public String getName() { return name; } public void setName(String name) { this.name = name; } @Column(name="DESCRIPTION") public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } } In the JSP, I need to get the data from the service field of Product also. So I in my JQuery callback function, I have written like product.service.description to get the data. It seems that by default Jackson is not mapping the associated service object (or any other custom object). Also I am not getting any exception. In the JSP, I do not get the data. It is working fine when I return Collection of some object which does not contain any other custom objects as its fields. Am I missing any settings for this to work? Thanks!

  • PHP: Where to place return 'false' value?

    - by Mike
    Is one of the following functions better than the other, in terms of where to place the 'return false' statement? Function #1: function equalToTwo($a, $b) { $c = $a + $b; if($c == 2) { return true; } return false; } Function #2: function equalToTwo($a, $b) { $c = $a + $b; if($c == 2) { return true; } else { return false; } } Thanks!
