You must run the script using `sudo`:

    sudo /path/to/script

But before you must allow `jenkins` to run the script in `/etc/sudoers`.

    jenkins    ALL = NOPASSWD: /path/to/script

@Igor Chubin&#39;s answer is 100% correct, but never open sudoer file with a normal editor. always use visudo

just type 

    sudo visudo

this will take you to `/etc/sudoers` and upon saving it will make sure that there is no error in formatting. 

if you make an error in sudoer file, you will lose sudo access, so always use `visudo`

I do realise I&#39;m late to the party on this question, but for reference sake I thought I&#39;d throw my 2c in here: I use the SSH plugin for Jenkins to accomplish this (simply configure a localhost target). In this way, I can contain the script directly within Jenkins (like a normal &quot;Execute shell&quot; step), instead of using sudo to invoke an external script.

Try adding jenkins user to sudo group

    sudo su -
    usermod -a -G sudo jenkins



Easy way to do it     
[![enter image description here][1]][1]

    $ sudo visudo
    ## Now add the below lines in your sudoers file :
    jenkins ALL=(ALL) NOPASSWD: ALL
    
    $service jenkins start

I have a view where there can be a large number of items for the user to scroll through and I&#39;d like to implement infinite scrolling to enable progressive loading of the content.   

It looks like some folks [have done pagination][1] but Google doesn&#39;t bring up anyone discussing how they&#39;ve done infinite lists with Ember/Ember Data.   Anyone already worked through this and have a blog post/example code to share?

I am attempting to detect WebGL support across multiple browsers and I&#39;ve encountered the following scenario. The current version of Firefox appears to report positive support using the following check, even when the visitor&#39;s video card is black-listed and/or WebGL is disabled:

    if (window.WebGLRenderingContext) {
        // This is true in Firefox under certain circumstances,
        // even when WebGL is disabled...
    }

I&#39;ve tried instructing my users to enable WebGL using the following steps. This has worked in some cases, but not always. Obviously, this is not something I can request of the general public:

 1. Type **about:config** in Firefox’s address bar
 2. To enable WebGL, set **webgl.force-enabled** to true

This has led me to create my own method for detecting support, which uses jQuery to inject a canvas element to detect support. This pulls on a number of techniques I found in various WebGL libraries and plugins. The trouble is, it is extremely difficult to test (any comments on whether the link below works for you are much appreciated!). To make this an objective question, **I would like to know if there&#39;s a universally accepted way to detect WebGL support across all browsers**.

I need to run a shell script in Jenkins as root instead of the default user. What do I need to change?

My sudoers file is like this:

    root    ALL=(ALL) ALL
    igx     ALL=(ALL) ALL
    %wheel  ALL=(ALL) ALL
    
    # Allow members of group sudo to execute any command
    # (Note that later entries override this, so you might need to move
    %sudo   ALL=(ALL) ALL
    #
    #includedir /etc/sudoers.d
    
    # Members of the admin group may gain root privileges
    %admin  ALL=(ALL) NOPASSWD:ALL
    root    ALL=(ALL) ALL
    jenkins ALL=NOPASSWD: /var/lib/jenkins/workspace/ing00112/trunk/source/

How can I pipe the stdout of multiple commands to a single command?  

Example 1: combine and sort the output of all three echo commands:

    echo zzz; echo aaa; echo kkk
desired output:

    aaa
    kkk
    zzz


Example 2: rewrite the following so that all the commands are in a single command-line using pipes, without redirects to a temp file:

    setopt &gt; /tmp/foo; unsetopt &gt;&gt; /tmp/foo; set &gt;&gt; /tmp/foo; sort /tmp/foo

I wanted to do grep for keywords with double quotes inside. To give a simple example:

I saw this interesting question at a comment on [cyberciti.biz](http://www.cyberciti.biz/faq/how-to-redirect-output-and-errors-to-devnull/).

That I found I even can&#39;t find a flexible way to do this in one-line command with sh.

As far my thought for the solution is:

    tmp_file=`mktemp`
    (./script 2&gt;$tmp_file &gt;/dev/null; cat $tmp_file) | ./other-script
    rm tmp_file

But you see, this is not synchronous, and fatally, it&#39;s so ugly.


Welcome to share you mind about this. :)

I need to run a java jar in server in order to communicate between two applications. I have written two shell scripts to run it, but once I start up that script I can&#39;t shut down / terminate the process. If I press &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;C&lt;/kbd&gt; or close the console, the server will shut down. Could anyone help me how to modify this script to run as a normal server?

I&#39;m currently trying to automate Django tests using Hudson CI, and am struggling to find an option that will automatically destroy the test database if it already exists (typically it will ask for confirmation to destroy it, which the automatic testing obviously cannot provide for).

Any suggestions would be much appreciated!

The horror stories I found while searching for an answer for this one...

OK, I have a .sh script which pretty much does everything Jenkins supposed to do:

 - checks out sources from SVN
 - build the project
 - deploys the project
 - cleans after itself

So in Jenkins I only have to &#39;build&#39; the project by running the script in an Execute Shell command.
 The script is ran (the sources are downloaded, the project is build/deploy) but then it marks the build as a failure:
Build step &#39;Execute shell&#39; marked build as failure
Even if the script was successfully ran! I tried closing the script with:

 - exit 0 (still marks it as failure)
 - exit 1 (marks it as failure, as expected)
 - no exit command at all (marks it as failure)

When, how and why does Execute Shell mark my build as a failure?

Recently, in our company, we decided to use _Ansible_ for deployment and continuous integration. But when I started using Ansible I didn&#39;t find modules for building Java projects with Maven, or modules for running JUnit tests, or JMeter tests. 

So, I&#39;m in a doubtful state: it may be I&#39;m using Ansible in a wrong way. 

When I looked at Jenkins, it can do things like build, run tests, deploy. The missing thing in Hudson is creating/deleting an instance in cloud environments like AWS.

So, in general, for what purposes do we need to use Ansible/Jenkins? For CI do I need to use a combination of Ansible and Jenkins?

Please throw some light on correct usage of Ansible. 

Is Ansible a replacement for a CI tool like Hudson/Jenkins?

Does anyone know how to increase the the timeout window before Jenkins logs out a user?  I&#39;m looking to raise it to 1 day or so.

I work in and out jenkins all day and we keep getting logged out between running of jobs.  Added to this frustration, the &#39;stay logged in&#39; checkbox doesn&#39;t seem to work either.

I do not want new users to be able to sign up. So in Jenkin&#39;s Configuration, I disabled &quot;Allow users to sign up&quot; with using Jenkin&#39;s own user database.

But how can I manually add users now?
Also, is there a default admin user I should take care of?

In Jenkins, is there a way to give different timeouts to each or selected build step?  
Build-time plugin out gives functionality of timeout &quot;Abort the build if it&#39;s stuck&quot; on complete project, what I need is to give different timeouts for each step. This way I can make my process more efficient.

For Jenkins using a Groovy System Script, is there a way to easily search the build queue and list of executing builds for some criteria (specifically a parameter that matches some condition) and then kill/cancel them? 

I cannot seem to find any way to do this, but it seems like it should be possible.

I am from Ukraine.  
When I open Jenkins in the browser I see all the UI in Russian.  
I am running Jenkins on Windows.  

However - there is no Russian in Windows configuration &quot;Region and Settings&quot;.
Format - English(United States).
Location - United States.
Only the Timezone is Ukrainian - UTC +02:00.

Is it possible to force Jenkins to show the UI in English language?

PS.
I did not have such a problem with Hudson before.

[Locale Plugin][1] helped to change the default locale to English.

  [1]: https://wiki.jenkins-ci.org/display/JENKINS/Locale+Plugin

I changed the language in the configuration of Chrome and now Jenkins is in English :)

What shell is used in Jenkins when calling the `shell` command? I&#39;m running Jenkins on a Linux machine.

What shell does Jenkins use?

so, i&#39;m trying to push some files to /system on android device (zte)
I&#39;ve rooted, connected with ADB, 

adb remount -&gt; I get permission denied
adb shell su -&gt; I&#39;m able to access shell and create folders etc and edit filesystem

(but in shell I can&#39;t copy a file from my computer to device)

Any help please

adb remount permission denied, but able to access super user in shell -- android

Basic question on ADB.

`adb root` restarts adb as root. But what i want is to restart it back to user after some time.

I tried the following :

    adb kill-server
    adb start-server

doesnt work..

`ps -A` -&gt; noted the process number of adb and killed it.. even this did not work. Finally i am restarting my device. Is there any way i can come back from root adb to general adb?

Thank you.

    DROP DATABASE db_name;
    ERROR 1010 (HY000): Error dropping database (can&#39;t rmdir &#39;./db_name&#39;, errno: 66)

How do I fix this issue?

I am continuously receiving this error.

I am using mySQL Workbench and from what I am finding is that root&#39;s schema privileges are null. There are no privileges at all.

I am having troubles across platforms that my server is used for and this has been all of a sudden issue.

**root@127.0.0.1** apparently has a lot of access but I am logged in as that, but it just assigns to localhost anyways - localhost has no privileges.  

I have done a few things like `FLUSH HOSTS`, `FLUSH PRIVILEGES`, etc
but have found no success from that or the internet.

How can I get root its access back? I find this frustrating because when I look around people expect you to &quot;have access&quot; but I don&#39;t have access so I can&#39;t go into command line or anything and `GRANT` myself anything.

When running `SHOW GRANTS FOR root` this is what I get in return:

&gt; Error Code: 1141. There is no such grant defined for user &#39;root&#39; on
&gt; host &#39;%&#39;

Access Denied for User &#39;root&#39;@&#39;localhost&#39; (using password: YES) - No Privileges?

I&#39;m writing a script that requires root level permissions, and I want to make it so that if the script is not run as root, it simply echoes &quot;Please run as root.&quot; and exits.

Here&#39;s some pseudocode for what I&#39;m looking for:

    if (whoami != root)
      then echo &quot;Please run as root&quot;
     
      else (do stuff)
    fi

    exit

How could I best (cleanly and securely) accomplish this? Thanks!

Ah, just to clarify: the (do stuff) part would involve running commands that in-and-of themselves require root. So running it as a normal user would just come up with an error. This is just meant to cleanly run a script that requires root commands, without using sudo inside the script, I&#39;m just looking for some syntactic sugar.
