Make your bash script runnable from every directory on the terminal

Have you ever wanted to create a utility like ls for example and make it available from everywhere in the linux's/mac's terminal?

There two ways to do that.

Way 1

(lets assume that my script is in a file with the name hello.)
a.move your script to /bin

sudo mv hello /bin/hello

b.make your script executable

sudo chmod +x /bin/hello

you are ready to ramble!


Way 2


create a file with different functions and aliases like the example bellow. Lets assume that the file name is .myfunc

the file might look like:


function hello {
echo "hello world!"
}
function again {
echo "hello again"
}
alias hi='echo hi'
view raw .myfunc hosted with ❤ by GitHub
Now on your home directory find a file called .bashrc. If you are using a different shell (like zsh) the file might be different. For example if you are using zsh you should look for .zshrc.

Mind that the file names starting with dot (.) in POSIX systems (like linux and macOs) are hidden files.

when you find the file .bashrc, edit it with VI or the editor of your choice and add somewhere (it does not matter where) the line
source {path to your .myfunc file}
If .myfunc is stored on the path ~/myscripts/.myfunc then the line on .bashrc should look something like the following

source ~/myscripts/.myfunc

You are almost done.  Now you either have to restart the terminal session or source the .bashrc

source .bashrc 

Now you are ready to call your supper useful functions hello, again and hi from wherever in the terminal.

try it ;)

DTOs conversion with reflection example - applied on Thymeleaf (or how to get read of Pojo's conversion boilerplate)

I was playing around with Thymeleaf the other day and I wanted to pass all values of my ModelAttribute POJO (Person.class in the example) to Spring's UI Model so I can use the values to the template. (Example to follow). A form is filled, and the values are passed to a controller that will render them to a new view (html) page. Nothing complex or useful, but just an alternative to hello world if you will. The ModelAttribute Person.class. Ignore the @ModelElement annotations for now. The main page that will render a simple form with 1 textfield (name),  one numeric field (age), one drop down menu to restrict the input values of a java enum (sex) and of course the submit button. When we click the submit button the following controller will be called, passing the values via the Person object. We then are passing them to Spring's model attribute so we can use them to our template. Lines 4-6 should belong in a different class but for simplicity I am putting them in the...

How to create a Cassandra container for testing with Keyspace and the latest schema with a single script call

Image
The problem: We have an application that uses Cassandra as the preferred persistence technology and we would like to have a one-command container running for local development and testing. In other words, we need the Cassandra container to have the Keyspace and the up-to-date schema following our migration scripts by executing something like   ./run_containerised_cassandra_locally.sh Breaking this problem into two sub-problems we identify that in order to do that we need a DB migration tool. In RDBMS we have tools like Flyway or Liquibase. For Cassandra, with a little bit of digging,  com.hhandoko:cassandra-migration  can be found. Which we can be incorporated into our codebase as a dependency or can exist as a standalone artefact (jar file) to be run on demand by a script. The latest is what we are going to use here. When we go to releases  of that repo, we can see the version of the jar with dependencies. (Current version cassandra-migration-0.17-jar-wit...
