Use the [find](https://www.mankier.com/1/find) command,

    find . -type f -name &quot;*John*&quot;

The `find` command will take long time because it scans real files in file system.

The quickest way is using `locate` command, which will give result immediately:

    locate &quot;John&quot;

If the command is not found, you need to install `mlocate` package and run `updatedb` command first to prepare the search database for the first time.

This is a very simple solution using the `tree` command in the directory you want to search for. `-f` shows the full file path and `|` is used to pipe the output of tree to `grep` to find the file containing the string `filename` in the name.

    tree -f | grep filename

use ack its simple.
just type `ack &lt;string to be searched&gt;`

    -(NSDate *)beginningOfDay:(NSDate *)date
    {
        NSCalendar *cal = [NSCalendar currentCalendar];
        NSDateComponents *components = [cal components:( NSMonthCalendarUnit | NSYearCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit ) fromDate:date];
        
        [components setHour:0];
        [components setMinute:0];
        [components setSecond:0];
        
        return [cal dateFromComponents:components];
        
    }
    
    -(NSDate *)endOfDay:(NSDate *)date
    {
        NSCalendar *cal = [NSCalendar currentCalendar];
        NSDateComponents *components = [cal components:(  NSMonthCalendarUnit | NSYearCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit ) fromDate:date];
        
        [components setHour:23];
        [components setMinute:59];
        [components setSecond:59];
        
        return [cal dateFromComponents:components];
    
    }


When I call : `[self endOfDay:[NSDate date]];` 
I get the first of the month ... Why is that? I use this two methods because I need an interval that is from the first second of the first date (beginningOfDay:date1) to the last second of the second date (endOfDay:Date2) ...

I searched and tried many ng-xxxx kind of options but couldn&#39;t find the one..
I just want to call some function in the controller when radio button is selected.

So it might be similar to following..(Of course, below code is not working)  

    &lt;input type=&quot;radio&quot; ng-model=&quot;value&quot; value=&quot;one&quot; ng-click=&quot;checkStuff()&quot;/&gt;


Is there any way to achieve what I want?

I&#39;m on Ubuntu, and I&#39;d like to find all files in the current directory and subdirectories whose name contains the string &quot;John&quot;. I know that `grep` can match the content of the files, but I have no idea how to use it with file names.

<p>I'm on Ubuntu, and I'd like to find all files in the current directory and subdirectories whose name contains the string "John". I know that <code>grep</code> can match the content of the files, but I have no idea how to use it with file names.</p>


I am using below to get previous, current and the next month under `Ubuntu` 11.04:

    LAST_MONTH=`date +&#39;%m&#39; -d &#39;last month&#39;`
    NEXT_MONTH=`date +&#39;%m&#39; -d &#39;next month&#39;`
    THIS_MONTH=`date +&#39;%m&#39; -d &#39;now&#39;`

It works well until today, the last day of October, 2012 (2012-10-31)

I get below result as of now:

    $ date
    Wed Oct 31 15:35:26 PDT 2012
    $ date +&#39;%m&#39; -d &#39;last month&#39;
    10
    $ date +&#39;%m&#39; -d &#39;now&#39;
    10
    $ $ date +&#39;%m&#39; -d &#39;next month&#39;
    12

I suppose the outputs should be `9`,`10`,`11` respectively.

Don&#39;t understand why `date` outputs behave like this. What should be a good way to get consistant `previous`, `current` and `next` month instead?

Here is my problem,

In Windows I am making a zip file in which there is a text .sh file which is supposed to be executed in Linux.
The user on the other end opens the zip file in Linux and tries to execute the .sh file but the execute permission is gone. So the user has to do it manually ( like explained here:[add execute permission][1].

How can I in Windows make the .sh executable and add it to a zip file so that when the zip file opens in linux the .sh file still retains its execute permission ( so that user doesn&#39;t have to do it manually)

I am trying to find an app that can detect faces in my pictures, make the detected face centered and crop 720 x 720 pixels of the picture. It is rather very time consuming &amp; meticulous to edit around hundreds of pictures I plan to do that.

I have tried doing this using [python opencv mentioned here][1] but I think it is outdated. I&#39;ve also tried [using this][2] but it&#39;s also giving me an error in my system. Also tried using face detection plugin for GIMP but it is designed for GIMP 2.6 but I am using 2.8 on a regular basis. I also tried doing what was posted at ultrahigh blog but it is very outdated (since I&#39;m using a Precise derivative of Ubuntu, while the blogpost was made way back when it was still Hardy). Also tried using Phatch but there is no face detection so some cropped pictures have their face cut right off.

I have tried all of the above and wasted half a day trying to make any of the above do what I needed to do.

Do you guys have suggestion to achieve a goal to around 800 pictures I have.

My operating system is Linux Mint 13 MATE.

Note: I was going to add 2 more links but stackexchange prevented me to post two more links as I don&#39;t have much reputation yet.

I have a web application that has to perform a repeated tasks, Sending messages and alerts, I, already, use a script page do those tasks when it loaded in the browser i.e http://example.com/tasks.php and I included it by the mean of iframe in every page of my web application.

Now I want to change this to use CRON jobs because the first approach may leads to jam performance, So How could I make a CRON job that visits http://example.com/tasks.php. However, I don&#39;t want this CRON job creating output files such as day.*!

I host the application on shared hosting service that permits CRON jobs via cPanel.

Under Linux, I&#39;ve been checking out matplotlib&#39;s animation class, and it seems to work except that I cant initialise the movie writer to write out the movie.

Using either of the examples:

 * &lt;http://matplotlib.org/examples/animation/moviewriter.html&gt;
 * &lt;http://matplotlib.org/examples/animation/basic_example_writer.html&gt;

results in the error &quot;**RuntimeError: No MovieWriters available!**&quot;

Im using matplotlib version 1.3.x and have installed (hopefully) all the codecs.

Can someone please suggest as to why I get this error? If its a codecs issue, which codecs (+versions) should I install?
If its something else that&#39;s broken, is there an alternative for creating animations in python?

I have several alphanumeric strings like these

    listOfNum = [&#39;000231512-n&#39;,&#39;1209123100000-n00000&#39;,&#39;alphanumeric0000&#39;, &#39;000alphanumeric&#39;]

The desired output for removing **trailing** zeros would be:

    listOfNum = [&#39;000231512-n&#39;,&#39;1209123100000-n&#39;,&#39;alphanumeric&#39;, &#39;000alphanumeric&#39;]

The desired output for **leading** trailing zeros would be:

    listOfNum = [&#39;231512-n&#39;,&#39;1209123100000-n00000&#39;,&#39;alphanumeric0000&#39;, &#39;alphanumeric&#39;]

The desire output for removing both leading and trailing zeros would be:

    listOfNum = [&#39;231512-n&#39;,&#39;1209123100000-n&#39;, &#39;alphanumeric&#39;, &#39;alphanumeric&#39;]

For now i&#39;ve been doing it the following way, please suggest a better way if there is:

    listOfNum = [&#39;000231512-n&#39;,&#39;1209123100000-n00000&#39;,&#39;alphanumeric0000&#39;, \

    for i in listOfNum:
      while i[-1] == &quot;0&quot;:
        i = i[:-1]
      trailingremoved.append(i)
    
    # Remove leading
    for i in listOfNum:

      leadingremoved.append(i)
      
    # Remove both

How do you do a *verbatim* string literal in VB.NET?

This is achieved in C# as follows:

    String str = @&quot;c:\folder1\file1.txt&quot;;

This means that the backslashes are treated literally and not as escape characters.

How is this achieved in VB.NET?

I have an archive, which is archived by someone else, and I want to automatically, after I download it, to change a branch of the file system within the extracted files to gain read access. (I can&#39;t change how archive is created).

I&#39;ve looked into this thread: https://stackoverflow.com/questions/6937885/chmod-how-to-recursively-add-execute-permissions-only-to-files-which-already-ha as into some others, but no joy.

The directories originally come with multiple but all wrong flags, they may appear as:

    drwx------
    d---r-x---
    drwxrwxr-x
    dr--r-xr--

Those are just the few I&#39;ve discovered so far, but could be more.

`find` errors when tries to look into a directory with no `x` permission, and so doesn&#39;t pass it to `chmod`. What I&#39;ve been doing so far, is manually change permissions on the parent directory, then go into the child directories and do the same for them and so on. But this is a lot of hand labour. Isn&#39;t there some way to do this automatically?

I.e. how I am doing it now:

do:

    $ chmod -R +x
    $ chmod -R +r

until I get no errors, then

    $ find -type f -exec chmod -x {} +

But there must be a better way.

I want to use the method of &quot;findall&quot; to locate some elements of the source xml file in the ElementTree module.

However, the source xml file (test.xml) has namespace. I truncate part of xml file as sample:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;iso-8859-1&quot;?&gt;
    &lt;XML_HEADER xmlns=&quot;http://www.test.com&quot;&gt;
    	&lt;TYPE&gt;Updates&lt;/TYPE&gt;
    	&lt;DATE&gt;9/26/2012 10:30:34 AM&lt;/DATE&gt;
    	&lt;COPYRIGHT_NOTICE&gt;All Rights Reserved.&lt;/COPYRIGHT_NOTICE&gt;
    	&lt;LICENSE&gt;newlicense.htm&lt;/LICENSE&gt;
    	&lt;DEAL_LEVEL&gt;
    		&lt;PAID_OFF&gt;N&lt;/PAID_OFF&gt;
            &lt;/DEAL_LEVEL&gt;
    &lt;/XML_HEADER&gt;

The sample python code is below:

    from xml.etree import ElementTree as ET
    tree = ET.parse(r&quot;test.xml&quot;)
    el1 = tree.findall(&quot;DEAL_LEVEL/PAID_OFF&quot;) # Return None
    el2 = tree.findall(&quot;{http://www.test.com}DEAL_LEVEL/{http://www.test.com}PAID_OFF&quot;) # Return &lt;Element &#39;{http://www.test.com}DEAL_LEVEL/PAID_OFF&#39; at 0xb78b90&gt;

Although it can works, because there is a namespace &quot;{http://www.test.com}&quot;, it&#39;s very inconvenient to add a namespace in front of each tag.

How can I ignore the namespace when using the method of &quot;find&quot;, &quot;findall&quot; and so on?

I&#39;m new to shell scripts, can anyone help? I want to delete scripts in a folder from the current date back to 10 days.
The scripts looks like:

    2012.11.21.09_33_52.script
    2012.11.21.09_33_56.script
    2012.11.21.09_33_59.script

The script will run in every 10 day with Crontab, that&#39;s why I need the current date.

    find . -type d

can be used to find all directories below some start point. But it returns the current directory (`.`) too, which may be undesired. How can it be excluded?

How to exclude this / current / dot folder from find &quot;type d&quot;

I always forget which file I edit one minutes ago, so I input `find . -cmin 1` or some other value but it worked exactly `1` minutes. I had to try `find . -ctime 2 /*or 3,4...*/`.

Then I find another approach which be better:

    touch -t 12251134 empty /*similar format which 5 or 10 minutes ago */
    find . -newer empty

I can use `date -d&#39;-5minutes&#39; +%m%d%H%M` caculate the time for me. I want to know if there is a simple way to find files accessed 1, 2 or 3... minutes ago.
