You can use vi text editor in Unix

vi [-eFGlRrSv] [-c cmd] [-t tag] [-w size] [file]

Vi is a screen oriented text editor. vi have different interfaces to the same program, and it is possible to switch back and forth during an edit session. View is the equivalent of using the -R (read-only) option of vi.

Command input for vi is read from the standard input. In the vi interface, it is an error if standard input is not a terminal.

Vi is a screen editor. This means that it takes up almost the entire screen, displaying part of the file on each screen line, except for the last line of the screen. The last line of the screen is used for you to give commands to vi, and for vi to give information to you.

The other fact that you need to understand is that vi is a modeful editor.

Ex:
dd Delete the line the cursor is on.
x Delete the character the cursor is on.
:w Save the Works that u done
:q Quit from vi editor
:q! Quit without saving the work that you edit

Do check your Unix system vi man pages for more info

vi

VI(1)							      General Commands Manual							     VI(1)

NAME

       vi - screen oriented (visual) display editor based on ex

SYNOPSIS

       vi [ -t tag ] [ -r ] [ +command ] [ -l ] [ -wn ] name ...

DESCRIPTION

       Vi (visual) is a display oriented text editor based on ex(1).  Ex and vi run the same code; it is possible to get to the command mode of ex
       from within vi and vice-versa.

       The Vi Quick Reference card and the Introduction to Display Editing with Vi provide full details on using vi.

FILES

       See ex(1).

SEE ALSO

       ex (1), edit (1), ``Vi Quick Reference'' card, ``An Introduction to Display Editing with Vi''.

AUTHOR

       William Joy
       Mark Horton added macros to visual mode and is maintaining version 3

BUGS

       Software tabs using ^T work only immediately after the autoindent.

       Left and right shifts on intelligent terminals don't make use of insert and delete character operations in the terminal.

       The wrapmargin option can be fooled since it looks at output columns when blanks are typed.  If a long word passes through the  margin  and
       onto the next line without a break, then the line won't be broken.

       Insert/delete  within  a  line  can  be slow if tabs are present on intelligent terminals, since the terminals need help in doing this cor-
       rectly.

       Saving text on deletes in the named buffers is somewhat inefficient.

       The source command does not work when executed as :source; there is no way to use the :append, :change, and :insert commands, since  it	is
       not possible to give more than one line of input to a : escape.	To use these on a :global you must Q to ex command mode, execute them, and
       then reenter the screen editor with vi or open.
