ubuntu18.04 vim

Ubuntu 18.04 comes with a pre-installed version of Vim, a popular text editor. You can access it by opening a terminal and typing 'vim' followed by the name of the file you want to edit. For example, to open a file named 'test.txt', you would run:

vim test.txt

Once inside Vim, you can use various commands to navigate, edit, and save the file. The basic commands include:

- `i` to enter insert mode and start editing the file
- `Esc` to exit insert mode and return to command mode
- `:w` to save the changes made to the file
- `:q` to quit Vim

These are just a few of the many commands available in Vim. It's a powerful and customizable text editor with a steep learning curve. If you're new to Vim, I recommend checking out tutorials or guides online to learn more about its features and usage.
