The 'vi' editor is a text editor; it can edit anything that is displayable ASCII text. You can edit a password in the password file using 'vi' (not recommended).
This is an unclear question, since Unix systems do not have password protected subdirectories. The 'vi' editor is either granted permission to edit a resource or denied, based on permissions (and not passwords).
You don't. The 'tar' command has nothing to do with the 'vi' editor; it creates an archive files and the vi editor modifies the content of a file.
'vi' is the standard text editor for Unix. You use it to edit content of a text file.
The 'vi' text editor may be used anywhere you want to edit/change/modify/add text to a file.
the text is inputed in vi editor by pressing the i key, that mean get the insert permission into vi editor
Everyone has their favorite editor - mine happens to be 'vi' because I use it frequently and it does in a simple way everything I need to do with editing.
gedit is a visual editor that can only be used in a graphical desktop environment. 'vi' is a standard and can be used in a terminal window without resorting to a desktop environment.
It seems as though your question has to do with an interactive prompt, which doesn't exist in the 'vi' editor. It is an editor program, and as such is only concerned with text based file changes.
Hmm... The recommended method of changing your password on Linux (or Unix for that matter), is to use the passwd command.To change another user's password, switch user to rootand issue the command:# passwd other_user Your question seems to indicate that you really want to directly edit your passwd and shadow files on your Linux distribution. Unless you really, really know what you're doing, I recommend against this.If you do know what you're doing, use the vi (or other editor - vi is the best editor ever made though) editor and directly edit your /etc/passwd and /etc/shadow files.Of course, should you subsequently discover you can no longer access your system, it may behoove you to go back to your Linux/Unix basics and begin all over again. May I suggest, as an excellent starting point, learn all that you can about the world's most wonder editor, the editor vi. :)
vi file name
Vi (pronounced vee-eye), the standard screen-oriented editor provided with Unix operating systems, is the ``visual'' mode of the Ex line editor. Both Vi and Ex commands can be issued from within Vi. Source-The Internet.
Your question is uncleear; every time you start the 'vi' editor you get another process.
