To make another symlink (will fizzle if symlink exists as of now):
***ln -s /path/to/file /path/to/symlink***
To make or improve a symlink:
***ln -sf /path/to/file /path/to/symlink***

You can utilize **grep - ilR**:
***grep -Ril "text-to-find-here" /***
**i** represents overlook case (discretionary for your situation).
**R** stands for recursive.
**l** means "show the document name, not simply the outcome".
**/** represents beginning at the root of your machine.

Use these some easy instructions:
***mysqldump -u username -p -v olddatabase > olddbdump.sql
mysqladmin -u username -p create newdatabase
mysql -u username -p newdatabase < olddbdump.sql***
Or on the other hand to decrease I/O utilize the following:
***mysqladmin -u username -p create newdatabase
mysqldump -u username -v olddatabase -p | mysql -u username -p -D newdatabase
***

Using JavaScript code:
***function hasClass(ele, cls) {
return ele.className.match(new RegExp('(\\s|^)' + cls + '(\\s|$)'));
}

function addClass(ele, cls) {
if (!this.hasClass(ele, cls)) ele.className += " " + cls;
}

function removeClass(ele, cls) {
if (hasClass(ele, cls)) {
var reg = new RegExp('(\\s|^)' + cls + '(\\s|$)');
ele.className = ele.className.replace(reg, ' ');
}
}

function replaceClass(ele, oldClass, newClass){
if(hasClass(ele, oldClass)){
removeClass(ele, oldClass);
addClass(ele, newClass);
}
return;
}

function toggleClass(ele, cls1, cls2){
if(hasClass(ele, cls1)){
replaceClass(ele, cls1, cls2);
}else if(hasClass(ele, cls2)){
replaceClass(ele, cls2, cls1);
}else{
addClass(ele, cls1);
}
}***

You can get from a distant vault, see the distinctions and afterwards pull or consolidation.

This is a model for a distant storehouse called **origin** and a branch called **master** following the far off **origin/master**:
***git checkout master
git fetch
git diff origin/master
git rebase origin master***

Every time you are creating plots you might get this error - "**Error in plot.new() : figure margins too large**". To avoid such errors you can first check **par("mar")** output. You should be getting:

***[1] 5.1 4.1 4.1 2.1***
To change that write:

***par(mar=c(1,1,1,1))***
This should rectify the error. Or else you can change the values accordingly.

Hope this works for you.

In my case, I was sending input elements instead of their values:

***$.post( '',{ registerName: $('#registerName') } )***
Instead of:

***$.post( '',{ registerName: $('#registerName').val() } )***
This froze my Chrome tab to a point it didn't even show me the 'Wait/Kill' dialog for when the page became unresponsive...

If you send a PHP array into a function that expects a string like: **echo** or **print**, then the PHP interpreter will convert your array to the literal string **Array**, throw this Notice and keep going. For example:
***
php> print(array(1,2,3))

PHP Notice: Array to string conversion in
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(591) :
eval()'d code on line 1
Array
***
In this case, the function **print** dumps the literal string: **Array** to stdout and then logs the Notice to stderr and keeps going.

*Another example in a PHP script:*
***
$stuff = array(1,2,3);
print $stuff; //PHP Notice: Array to string conversion in yourfile on line 3
?>
***

You need to add the path of your pip installation to your PATH system variable. By default, pip is installed to **C:\Python34\Scripts\pip** (pip now comes bundled with new versions of python), so the path "C:\Python34\Scripts" needs to be added to your PATH variable.

To check if it is already in your PATH variable, type **echo %PATH%** at the CMD prompt

To add the path of your pip installation to your PATH variable, you can use the Control Panel or the **setx** command. For example:

***
setx PATH "%PATH%;C:\Python34\Scripts"
***

How about this one? lot cleaner and all in single line.
***
foreach ((array) $items as $item) {
// ...
} ***

If your source code name is HelloWorld.java, your compiled code will be **HelloWorld.class.**

You will get that error if you call it using:

***java HelloWorld.class***
Instead, use this:

***java HelloWorld***

Other posters are probably correct...there might be spaces mixed in with your tabs. Try doing a search & replace to replace all tabs with a few spaces.

Try this:

***
import sys

def Factorial(n): # return factorial
result = 1
for i in range (1,n):
result = result * i
print "factorial is ",result
return result

print Factorial(10)***
