Alternatively you can use a &quot;.&quot; instead of *, as this will take all the files in the working directory, include the folders and subfolders:

    FROM ubuntu
    COPY . /
    RUN ls -la /


To **merge** a local directory into a directory within an image, do this.
It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

```
COPY ./local-path/. /image-path/
```

If you want to copy a source directory entirely with the same directory structure,
Then don&#39;t use a star(*). Write COPY command in Dockerfile as below.

    COPY . destinatio-directory/ 

I am looking for a way to concatenate the strings of a field within a group by query. So for example, I have a table:

    ID   COMPANY_ID   EMPLOYEE
    1    1            Anna
    2    1            Bill
    3    2            Carol
    4    2            Dave

and I wanted to group by company_id to get something like:

    COMPANY_ID   EMPLOYEE
    1            Anna, Bill
    2            Carol, Dave



There is a built-in function in mySQL to do this [group_concat][1]

My situation is this... someone working on the same repo has deleted a branch from his local &amp; remote repo...

Most people who have asked about this kind of problem on Stack Overflow, or other sites have the issue of branches still showing in their remote tracking branch list `git branch -a` at the bottom:

    * master
      develop
      feature_blah
      remotes/origin/master
      remotes/origin/develop
      remotes/origin/feature_blah
      remotes/origin/random_branch_I_want_deleted

However, in MY situation the branch that shouldn&#39;t be there, is local:

    * master
      develop
      feature_blah
      random_branch_I_want_deleted
      remotes/origin/master
      remotes/origin/develop
      remotes/origin/feature_blah


When I do any of the following, it doesn&#39;t get removed locally:

    $ git prune

I also tried:

    $ git remote prune origin
    $ git fetch --prune


More useful info:  When I check `git remote show origin` this is how it looks:

    * remote origin
    Fetch URL: utilities:homeconnections_ui.git
    Push  URL: utilities:homeconnections_ui.git
    HEAD branch: master
    Remote branches:
     master                        tracked
     develop                       tracked
     feature_blah                  tracked
     other123                      tracked
     other444                      tracked
     other999                      tracked
    Local branches configured for &#39;git pull&#39;:
     develop                      merges with remote develop
     feature_blah                 merges with remote other999
     master                       merges with remote master
     random_branch_I_want_deleted merges with remote random_branch_I_want_deleted
    Local refs configured for &#39;git push&#39;:
     develop         pushes to develop     (local out of date)
     master          pushes to master      (up to date)
     feature_blah    pushes to feature_blah(up to date)

Notice that it&#39;s only in the section titled `Local branches configured for &#39;git pull&#39;:`

We use copy command to copy data of one table to a file outside database.

Is it possible to copy data of one table to another table using command.

If yes can anyone please share the query.

Or is there any better approach like we can use pg_dump or something like that.

... how to copy file with pathlib in Python 2.7?



Copy file with pathlib in Python

I have no knowledge of JavaScript, but I managed to put this code together using bits and bolts from various Stack&amp;nbsp;Overflow answers. It works OK, and it outputs an array of all selected checkboxes in a document via an alert box.

    function getSelectedCheckboxes(chkboxName) {
      var checkbx = [];
      var chkboxes = document.getElementsByName(chkboxName);
      var nr_chkboxes = chkboxes.length;
      for(var i=0; i&lt;nr_chkboxes; i++) {
        if(chkboxes[i].type == &#39;checkbox&#39; &amp;&amp; chkboxes[i].checked == true) checkbx.push(chkboxes[i].value);
      }
      return checkbx;
    }

And to call it I use:

    &lt;button id=&quot;btn_test&quot; type=&quot;button&quot; &gt;Check&lt;/button&gt;
    &lt;script&gt;
        document.getElementById(&#39;btn_test&#39;).onclick = function() {
            var checkedBoxes = getSelectedCheckboxes(&quot;my_id&quot;);
            alert(checkedBoxes);
        }
    &lt;/script&gt;

Now I would like to modify it so when I click the `btn_test` button the output array `checkbx` is copied to the clipboard. I tried adding:

    checkbx = document.execCommand(&quot;copy&quot;);

or

    checkbx.execCommand(&quot;copy&quot;);

at the end of the function and then calling it like:

    &lt;button id=&quot;btn_test&quot; type=&quot;button&quot; onclick=&quot;getSelectedCheckboxes(&#39;my_id&#39;)&quot;&gt;Check&lt;/button&gt;

But it does not work. No data is copied to clipboard.


Copy output of a JavaScript variable to the clipboard

I&#39;m using this function to copy a URL to the clipboard:

    function CopyUrl($this){
		
	  var querySelector = $this.next().attr(&quot;id&quot;);
	  var emailLink = document.querySelector(&quot;#&quot;+querySelector);

	  var range = document.createRange();
	  range.selectNode(emailLink);  
	  window.getSelection().addRange(range);  
		
	  try {  
		// Now that we&#39;ve selected the anchor text, execute the copy command  
		var successful = document.execCommand(&#39;copy&#39;, false, null);
		var msg = successful ? &#39;successful&#39; : &#39;unsuccessful&#39;; 
		
		if(true){
			$this.addClass(&quot;copied&quot;).html(&quot;Copied&quot;);
		}
		
	  } catch(err) {  
		console.log(&#39;Oops, unable to copy&#39;);  
	  }  
		
	  // Remove the selections - NOTE: Should use   
	  // removeRange(range) when it is supported  
	  window.getSelection().removeAllRanges();
    }

Everything works fine on desktop browsers, but not on iOS devices, where my function returns successfully, but the data isn&#39;t copied to the clipboard at all. What&#39;s causing this and how could I solve this problem?

Is there any way to copy multiple directories in one command, to reduce the number of layers? E.g., instead of:

    COPY dirone ./dirone
    COPY dirtwo ./dirtwo
    COPY dirthree ./dirthree

I want to do:

    COPY dirone/ dirtwo/ dirthree/ ./

However, this copies the *contents* of the directories... but I want to copy *the directories themselves*.


Copy multiple directories with one command

Docker gives you a way of listing running containers or all containers including stopped ones.

This can be done by:

    $ docker ps # To list running containers

Or by

    $ docker ps -a # To list running and stopped containers

Do we have a way of only listing containers that have been stopped?


List only stopped Docker containers

I have a `docker-compose.yml` which contain several containers.  Three of them are for my app (client, server and database) and the rest are for various dev tools (e.g. psql, npm, manage.py, etc).  When I do `docker-compose up` all of them are started, but I only want the three main ones to start.  Because of the links I&#39;ve specified, I can start just those three with `docker-compose up client` but then the output is only from that one container. So, is there a way to do one of the following:

1. Tell docker-compose which containers should by started by `docker-compose up`
2. Get output from all linked containers from `docker-compose up client`

docker-compose up for only certain containers

I have an app whose only dependency is flask, which runs fine outside docker and binds to the default port `5000`. Here is the full source:

    from flask import Flask
     
    app = Flask(__name__)
    app.debug = True
     
    @app.route(&#39;/&#39;)
    def main():
        return &#39;hi&#39;
     
    if __name__ == &#39;__main__&#39;:
        app.run()

The problem is that when I deploy this in docker, the server is running but is unreachable from outside the container.

Below is my Dockerfile. The image is ubuntu with flask installed. The tar just contains the `index.py` listed above;

    # Dockerfile
    FROM dreen/flask
    MAINTAINER dreen
    WORKDIR /srv

    # Get source
    RUN mkdir -p /srv
    COPY perfektimprezy.tar.gz /srv/perfektimprezy.tar.gz
    RUN tar x -f perfektimprezy.tar.gz
    RUN rm perfektimprezy.tar.gz

    # Run server
    EXPOSE 5000
    CMD [&quot;python&quot;, &quot;index.py&quot;]

Here are the steps I am doing to deploy

`$&gt; sudo docker build -t perfektimprezy .`

As far as I know the above runs fine, the image has the contents of the tar in `/srv`. Now, let&#39;s start the server in a container:

    $&gt; sudo docker run -i -p 5000:5000 -d perfektimprezy
    1c50b67d45b1a4feade72276394811c8399b1b95692e0914ee72b103ff54c769

Is it actually running?

    $&gt; sudo docker ps
    CONTAINER ID        IMAGE                   COMMAND             CREATED             STATUS              PORTS                    NAMES

    $&gt; sudo docker logs 1c50b67d45b1
     * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
     * Restarting with stat

Yep, seems like the flask server is running. Here is where it gets weird. Lets make a request to the server:

     $&gt; curl 127.0.0.1:5000 -v
     * Rebuilt URL to: 127.0.0.1:5000/
     * Hostname was NOT found in DNS cache
     *   Trying 127.0.0.1...
     * Connected to 127.0.0.1 (127.0.0.1) port 5000 (#0)
     &gt; GET / HTTP/1.1
     &gt; User-Agent: curl/7.35.0
     &gt; Host: 127.0.0.1:5000
     &gt; Accept: */*
     &gt;
     * Empty reply from server
     * Connection #0 to host 127.0.0.1 left intact
     curl: (52) Empty reply from server

Empty reply... But is the process running?

    $&gt; sudo docker top 1c50b67d45b1
    UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD
    root                2084                812                 0                   10:26               ?                   00:00:00            python index.py
    root                2117                2084                0                   10:26               ?                   00:00:00            /usr/bin/python index.py

Now let&#39;s ssh into the server and check...
