Determine the total size of a directory (folder) from the command line Linux

The command du "summarizes disk usage of each FILE, recursively for directories," e.g.,

du -hs /path/to/directory

-h is to get the numbers "human readable", e.g. get 140M instead of 143260 (size in KBytes)
-s is for summary (otherwise you'll get not only the size of the folder but also for everything
in the folder separately)

From man tree:

-h Print the size of each file but in a more human readable way, e.g. appending a size
letter for kilobytes (K), megabytes (M), gigabytes (G), terabytes (T), petabytes (P) and
exabytes (E).

--du For each directory report its size as the accumulation of sizes of all its files and
sub-directories (and their files, and so on). The total amount of used space is also given
in the final report (like the 'du -c' command.)

Object serialization in java

Serialization is the conversion of an object to a series of bytes, so that the object can be easily saved to persistent storage or streamed across a communication link. The byte stream can then be deserialized - converted into a replica of the original object. When you want to serialize an object, that respective class should implement the marker interface serializable. It just informs the compiler that this java class can be serialized. You can tag properties that should not be serialized as transient. You open a stream and write the object into it. Code for serialization of a java class : Data.java package com . codetalk . serialization ; import java.io.Serializable ; public class Data implements Serializable { private static final long serialVersionUID = 1L; private String firstName ; private String lastName ; /** * @return the firstName */ public String getFirstName () { return firstName ; } /** * @param firstNam...
