The Vim commands-Linux

 < The list of Vim commands >

Working with files
Vim commandAction
:e filenameOpen a new file. You can use the Tab key for automatic file name completion, just like at the shell command prompt.
:w filenameSave changes to a file. If you don't specify a file name, Vim saves as the file name you were editing. For saving the file under a different name, specify the file name.
:qQuit Vim. If you have unsaved changes, Vim refuses to exit.
:q!Exit Vim without saving changes.
:wqWrite the file and exit.
:xAlmost the same as :wq, write the file and exit if you've made changes to the file. If you haven't made any changes to the file, Vim exits without writing the file.
These Vim commands and keys work both in command mode and visual mode.
Vim commandAction
j or Up ArrowMove the cursor up one line.
