I have a filename @! in my home folder. When I open it, it has the same content that my other bash file myscript.sh has.
I have not assign execute permission to original bash file. When I have checked properties, the only difference between two file is size. Original file size is 1.1 KB and @! file size is 714 bytes. How is it automatically created?
Are there scenarios where vi is the only option to create, edit or modify a file in an Ubuntu environment?
My question is basically to really know if there is such a case where I would be forced to use vi because it would be the only option available in a particular case in the Ubuntu ecosystem.
Could a particular case exist where I somehow would not have access to other options like nano, pico or simply sending the information with tools like cat, sed, tee and more?
I would assume this is more of a server or cloud side since on the Desktop there are many more options, but from anybody that uses the terminal a lot I ask:
Is there such a case?
I really hope someone on this subject can help me.
I recently enrolled for a programming course and one subject requires me to program in c/c++ on Linux os. I've had previous c++ experience on the .net framework building console apps and winforms.
The problem is this course wants us not to use any IDE of any sort, the only thing we allowed to use is the terminal and something called 'vi commands'. How can get started with?
I am new to vi, actually I have started learning vi from today and I have got stuck at the behavior of the backspace key.
Actually when I fired up vi on my Ubuntu 12.04 for the first time my backspace key was working normally but after that it has started behaving strangely. Whenever I press the backspace in the insert mode it just moves one place to the left instead of erasing the character.
How can I get back the default backspace functionality? Please note that I don't want to install vim or set nocompatibilty.
Apparently Ubuntu 11.10 uses Vim when I type
vi filename
How do I force Ubuntu to use Vi instead?
