Editing files

Editing files

This topic describes the main tools you use to edit files: The UnixWare system has several editors, which are useful for different purposes:

vi
Visual editor. vi allows you to perform full-screen writing and editing of files; this is the editor you will use most.

view
Read-only version of vi. view allows you to examine text files, but does not allow you to save changes. See vi(1).

ed
Original UNIX system line editor. ed is line-oriented; it can only edit a line at a time. Used within shell scripts, and when it is impossible to configure a terminal properly. See ``Using ed'' for details.

ex
A line editor. Like ed, ex is line-oriented. Like view, ex is implemented as part of vi, and the ex command is a link to vi. See vi(1).

sed
Stream editor. sed reads an input file, carries out a sequence of commands, and writes the result to its output file. It cannot be used interactively. (See ``Manipulating text with sed'' for further details.)
