The snap list command is used to display the installed snaps on the system1. Snaps are self-contained software packages that can be installed and updated across different Linux distributions2. The snap list command shows the name, version, revision, developer and notes of each snap1.

The snap find command is used to search for snaps in the Snap Store, which is an online repository of snaps2. The snap install command is used to install snaps from the Snap Store or from a local file2. The snap try command is used to test a snap without installing it, by mounting a directory that contains the snap files2. These commands are not useful for verifying if a package was installed using a snap.

The vi text editor is a popular and powerful tool for editing text files on Linux systems. The vi editor has two modes: command mode and insert mode. In command mode, the user can issue commands to manipulate the text, such as moving the cursor, deleting, copying, pasting, searching, replacing, and saving. In insert mode, the user can type text into the file. To switch from command mode to insert mode, the user can press various keys, such as i, a, o, I, A, or O. To switch from insert mode to command mode, the user can press the Esc key.

To insert a character at the end of the current line in the vi editor, the user can press the A key in command mode. This will move the cursor to the end of the line and switch to insert mode. Then, the user can type the desired character and press Esc to return to command mode. The statement D is correct.

The statements A, B, C, and E are incorrect because they do not perform the desired task. The p key in command mode will paste the previously copied or deleted text after the cursor. The r key in command mode will replace the character under the cursor with another character. The bb key in command mode will move the cursor back two words. The i key in command mode will switch to insert mode before the cursor. References: [How to Use vi Text Editor in Linux]
