ed
ED(1) General Commands Manual ED(1)NAME
ed - editor
SYNOPSIS
ed file
OPTIONS
- Suppress line/byte count messages (for in scripts)
EXAMPLES
ed prog.c # Edit prog.c
echo '1,$p' | ed - file
# Odd way to write 'cat file'
DESCRIPTION
Ed is functionally equivalent to the standard V7 editor, ed. It supports the following commands:
(.) a: append
(.,.)c: change
(.,.)d: delete
e: edit new file"
f: print name of edited file"
(1,$)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.
