S. -P. Yong ARES

Vim • Under unix shell – vim – start an empty file – vim filename – open a file to edit • Save or quit file – : w xxx. x – save as xxx. x – : w – save the current file – : q – quit current file, discard any change – : q! – quit the current file, discard any change – : wq! – save and exit the current file S. -P. Yong ARES

Editing • Under insert mode – append text after the cursor – A – append text at the end of the line – i – append text before the cursor – I – append text before the first non-blank in the line – open a new line below the current line – O – open a new line above the current line • Esc – end insert mode, back to normal mode S. -P. Yong ARES

Deleting Text • When you typed something wrong – Under normal mode – x – delete one character under the cursor (or Delete) – nx – delete n characters under the cursor – X – delete one character before the cursor – D – delete from the current cursor to the end of line – dd – delete one line – s – delete one character and enter insert mode – S – delete one line and move the cursor to the beginning of the line – cw – change a word S. -P.
