DESCRIPTION

       Ed is functionally equivalent to the standard V7 editor, ed.  It supports the following commands:

	    (.) a: append
	    (.,.)c: change
	    (.,.)d: delete
		e: edit new file"
		f: print name of edited file"
	    (1,$)g: global command
	    (.) i: insert
	    (.,.+1)j: join lines together
	    (.) k: mark
	    (.) l: print with special characters in octal
	    (.,.)m: move
	    (.,.)p: print
		q: quit editor"
	    (.) r: read in new file
	    (.,.)s: substitute
	    (1,$)v: like g, except select lines that do not match
	    (1,$)w: write out edited file
       Many of the commands can take one or two addresses, as indicated above.	The defaults are shown in parentheses.	Thus a appends to the cur-
       rent line, and g works on the whole file as default.  The dot refers to the current line.  Below is a sample editing session with  comments
       given following the # symbol.

	    ed prog.c		# Edit prog.c
	    3,20p		# Print lines 3 through 20
	    /whole/		# Find next occurence of whole
	    s/whole/while/	# Replace whole by while
	    g/Buf/s//BUF/g	# Replace Buf by BUF everywhere
	    w			# Write the file back
	    q			# Exit the editor
       Ed  is  provided  for  its  sentimental value.  If you want a line-oriented editor, try ex.  If you want a good editor, use elle, elvis, or
       mined.
