I am trying to edit a text file through the shell console and i open it by typing "vi {filename} push i to inster text then i dont know how to save it. When i close the shell and open it again, the file is still what it used to be. Help please.
Start as root.
#vi filneame
press "Insert" for edit mode
edit what you like
press "Esc" lo leave "Edit mode"
type :wq! and press "Enter" to save and quit...
Check out "pico filename.txt"
Common options are listed plainly at the bottom of the screen (CTRL plus the named key).
Midnight Commander ("mc") is also a nice way to navigate and edit files. Options using the function keys are listed.
To edit system files you would still need to switch user ("su") to root.
