How To Find A File In Linux(Through The Shell)

-
In *nix family of operating systems, we can find a file easily with the help of find command.

 SYNTAX : $ find {directory-name} -name {filename}

 To find a file in root directory :

 Sometimes, it happens that we don't have any clue about the location of the file we are trying to search. In such a case we can search the entire system via the root directory (/). For example, if we want to search for a file named demo.txt, but we don't know where it could probably be present, then we would do something like this :

 $ sudo find / -name 'demo.txt'

 NOTE : Sometimes we may need special privileges to search for a particular file, so we'll use 'sudo' for that.

 To find a file in a specific directory :

 If we know the probable location of the file, but not sure about it, we can do this :

 $ sudo find /path/of/the/directory -name 'demo.txt'

Fun with HBase shell

-
Image
HBase shell is great, specially while getting yourself familiar with HBase. It provides lots of useful shell commands using which you can perform trivial tasks like creating tables, putting some test data into it, scanning the whole table, fetching data from a specific row etc etc. Executing  help  on HBase shell will give you the list of all the HBase shell commands. If you need help on a specific command, type help "command" . For example, help "get" will give you a detailed explanation of the get command. But this post is not about the above said stuff. We will try to do something fun here. Something which is available, but less known. So, get ready, start your HBase daemons, open HBase shell and get your hands dirty. For those of us who are unaware, HBase shell is based on  JRuby , the Java Virtual Machine-based implementation of Ruby. More specifically, it uses the  Interactive Ruby Shell (IRB) , which is used to enter Ruby commands and get an immedia

BETWEEN OPERATOR IN HIVE

-
Hive is a wonderful tool for those who like to perform batch operations to process their large amounts of data residing on a Hadoop cluster and who are comparatively new to the NOSQL world. Not only it provides us warehousing capabilities on top of a Hadoop cluster, but also a superb SQL like interface which makes it very easy to use and makes our task execution more familiar. But, one thing which newbies like me always wanted to have is the support of BETWEEN operator in Hive. Since the release of version 0.9.0  earlier  this year, Hive provides us some new and very useful features. BETWEEN operator is one among those.

HOW TO SETUP AND CONFIGURE 'ssh' ON LINUX (UBUNTU)

-
SSH (Secure Shell) is a network protocol  secure data communication, remote shell services or command execution and other secure network services between two networked computers that it connects via a secure channel  over an insecure network. The ssh server runs on a machine (server) and ssh client runs on another machine (client). ssh has 2 main components : 1- ssh : T he command we use to connect to remote machines - the client.  2-  sshd : T he daemon that is running on the  server  and allows clients to connect to the server. ssh is pre-enabled on Linux, but in order to start sshd daemon , we need to install ssh first. Use this command to do that : $ sudo apt-get install ssh This will install ssh on your machine. In order to check if ssh is setup properly do this : $ which ssh It will throw this line on your terminal /usr/bin/ssh $ which sshd It will throw this line on your terminal /usr/bin/sshd SSH uses  public-key cryptography  to  authenticate  the remote co
