Hello Linuxers !
I just write some lines here in the Vim for filling the screen.
You might feel easier to write things when switched to Insert mode in Vim.
:p
You can move cursor here by: h <-, j up, k down, l ->.
to the head of the line: 0 ; to the end of the line: $; move word by word: w.
save file :w [file_name] ; add '!' to force these command to execute.
[mo@mos-computer ~]$ vim myFile
