Linux graphical interface and command line interface switching method with each other:
- If the default is the graphical interface:
The Root mode: vi / etc / default / grub
Non-Root mode: sudo vi / etc / default / grub
Here you can see default = "quiet splash", it is the way to start the graphical interface ubuntu
- Comment out this line, using the "text" line, if this line does not add a line to the specific shortcut keys, please refer to the article below, save and exit (press Esc +:! Wq + Enter)
- The Root Mode: update-grub
Non-Root mode: sudo update-grub
- Under Root mode: reboot
Non-Root mode: sudo reboot
After the reboot into the command line to start ubuntu
-
Conversely converted to graphical interface from the command line, same step, the text commented, enabled default = "quiet splash" line.

After the Linux vi file, use a variety of keyboard shortcuts
For example, I want to copy the contents of a line and follow the insertion of characters:
/ Xx: Type what you want after a carriage return after the slash
n: cursor to the next qualifying query content
N: position the cursor to a query on the contents of qualified
Enter: Move the cursor down one line
yy: Copy the contents of the line where the cursor row
P: Paste copied out of line
Space space or End->: Move the cursor right one character
Backspace: the cursor one position to the left
x: Move the cursor to delete the selected character
u: Undo the last step of the operation
Ctrl + r: recovery, that is a command before the rollback
U: OK, cancel all operations on a previous line edit
i: content before inserting the input i, then enter Inserts
Then press Esc to exit the insert mode
Arrow PgUp: Move the cursor to the line
dd: delete the row cursor
10dd: delete including 10 lines under the cursor line content
: Q !: exit without saving
