Mac OS List directory in tree view using find command.

Posted by Nimeshka Srimal Wednesday, February 15, 2023 2 comments

In mac (also in a Linux systems) you will have to install an additonal package called `tree` to display the content of folder in a tree view. 

 

 

 

But what if you are like me; someone who doesn't like to install additional packages just for a simple task? Well, you are at the right place then. 

 

Here is a nice command to get that done for you. Just run the following. 

 

 find . -print | sed -e 's;[^/]*/;|____;g;s;____|; |;g' 


That's just it. You should see a nice tree output as shown in the above screenshot :) 

 

You could also convert this to a shell function, or an alias with a parameter to run this easily in the future.

Pretty print Curl JSON responses in terminal

Posted by Nimeshka Srimal Thursday, January 7, 2021 7 comments

Today I wanted to test one of my APIs and used curl to get the response in the terminal. The output wasn't clear at all because it usually returns everything in one line. 

 

Fortunately, there was a way to pretty-print the response, as in real json format. All you have to do is pipe the json_pp command after your curl command.

 

Ex: 


curl --location --request GET 'http://my.api.local/api' --header '...' | json_pp

 

and that's it. You should see a formatted json response.

Hope this will help someone. Please feel free to comment and let me know if you know any other better way :)

Solved - How to exit a telnet session?

How to exit a telnet session?
How to exit a telnet session?
It's funny, but I was fumbling with the terminal to exit a telnet session today. I rarely have to use telnet so I'm not much experienced with it. But if someone ever want to exit from a telnet session this is what you have to do.

Basically when you start a telnet session, this is what you would see most of the times:

~$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Now what? Pressing Ctrl + c, z, x, d will not do anything. I was too lazy that I didn't pay much attention to what was printed in the console. If I had read that, I would have easily exit the session.

It says:  Escape character is '^]'.

So that's it. You need to press Ctrl + ] keys and it will take you back to the telnet prompt where you can either press Ctrl + D or enter the command "quit" and press enter.

~$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
^]
telnet> quit
Connection closed.

One thing to note is that I use Terminator as my terminal emulator and this method doesn't work in it. I Still can't exit from that (: But this definitely works in the gnome terminal.

I hope this will help someone :) Please don't forget to leave a comment if you ever come across this post. Feel free to correct me or add any methods you know other than this.
