LINUX Move and copy files using SSH

Often you will need to move one or more files/folders or copy them to a different location. You can do so easily using an SSH connection. The commands which you would need to use are mv (short from move) and cp (short from copy).
The mv command syntax looks like this:
mv configuration.php-dist configuration.php
By issuing the above command we will move (rename) the file configuration.php-dist to configuration.php.
You can also use mv to move a whole directory and its content:
mv includes/* ./
This will move all files (and folders) in the includes/ directory to the current working directory.
In some cases however, we will need to only update the files and move only files that were changed, which we can do by passing ‘-u’ as argument to the command:
mv -u includes/* admin/includes
The copy (cp) command works the same way as mv, but instead of moving the files/folders it copies them. For example:
cp configuration.php-dist configuration.php
The command will copy the configuration.php-dist file to configuration.php and will preserve the original file (the file will NOT be removed after it is copied).
cp also accepts various arguments:
cp -R includes/ includes_backup/
-R instructs cp to copy files recursively (for example, a whole directory). To overwrite already existing files you should use the -f argument:
cp -Rf includes/ admin/includes/A more convenient way to copy files/folders is to use a 3rd party application, such as Midnight Commander. All our servers have mc (midnight commander) installed and it is available by executing the appropriate (mc) command using the command prompt.  Once inside the application you will see two sections - left and right. You can easily copy/move files from the left side directory to the right side using a semi-visual approach. You can even use your mouse to select files and function keys to execute commands.

C++ How to use Date and Time

The C++ standard library does not provide a proper date type. C++ inherits the structs and functions for date and time manipulation from C. To access date and time related functions and structures, you would need to include <ctime> header file in your C++ program. There are four time-related types: clock_t, time_t, size_t , and tm . The types clock_t, size_t and time_t are capable of representing the system time and date as some sort of integer. The structure type tm holds the date and time in the form of a C structure having the following elements: struct tm { int tm_sec ; // seconds of minutes from 0 to 61 int tm_min ; // minutes of hour from 0 to 59 int tm_hour ; // hours of day from 0 to 24 int tm_mday ; // day of month from 1 to 31 int tm_mon ; // month of year from 0 to 11 int tm_year ; // year since 1900 int tm_wday ; // days since sunday int tm_yday ; // days since January 1st int tm_isdst ; // hours of daylight savin...

PHP Error and Exception Handling

Error handling is the process of catching errors raised by your program and then taking appropriate action. If you would handle errors properly then it may lead to many unforeseen consequences. Its very simple in PHP to handle an errors. Using die() function: While wirting your PHP program you should check all possible error condition before going ahead and take appropriate action when required. Try following example without having /tmp/test.xt file and with this file. <?php if(!file_exists("/tmp/test.txt")) { die("File not found"); } else { $file=fopen("/tmp/test.txt","r"); print "Opend file sucessfully"; } // Test of the code here. ?> This way you can write an efficient code. Using abive technique you can stop your program whenever it errors out and display more meaningful and user friendly meassage. Defining Custom Error Handling Function: You can write your own function to handling any error. PHP provides y...
