Questions[text-editor](ubuntu)

What are the default text editors (GUI and CLI) in different flavors of Ubuntu. what commands should we use to edit files with them?

Behind the question

I tried Kubuntu and want to try more Ubuntu flavors and other distros, but when I was in Kubuntu I tried so hard to run gksu gedit /path/file.txt which wont work because gedit isn't the default text editor in Kubuntu, it's kate. I'm glad nano was available. but if I want to try more flavors I must know what are the default text editors in various Ubuntu flavors

I'd like to replace gedit, and use Sublime Text 3 as my default text editor for all text files on my Ubuntu system. Can you let me know how do I go about making this change?

When I tried to use arrow keys in insert mode in vi editor the following characters are being inserted in the editor:

• for ↓ I get B,
• for ↑ I get A,
• for ← I get D,
• for → I get C.

Please help me in resolve this problem.

I want to know how I can find and replace a specific text in multiple files like in Notepad++ in the linked tutorial.

e.g.: http://cybernetnews.com/find-replace-multiple-files/

Sometimes I want the last line of a text file to be a simple string of text with no newline character appended: ...eg. to concatenate another file to it.

Several editors automatically modify my text by adding a newline character, even though I have not pressed Enter.

Remains unmodified: Emacs, SciTE, Kate, Bluefish, Notepad(wine)

Newline is added: Gedit, Gvim, Vim, Nano

I would like to know if there is some way to tweak Gedit, Gvim, and Vim to only save what I have typed.... and even Nano might come in handy

I currently use Gedit, and I'm dabbling in Gvim/Vim.. so it would be useful to know how to "toggle" these on/off...

PS. Upon re-opening the same file in Gedit, Gvim, and Vim, the cursor's end-of-file placement is at the end of the text, whereas it should really show up on the next (empty) line. This is misleading (but that's because of what I'm used to).

I used a hexeditor to check the above observatons.
