| 22 | .SH DESCRIPTION
|
|---|
| 23 | .PP
|
|---|
| 24 | \fIEd\fR is functionally equivalent to the standard V7 editor, ed.
|
|---|
| 25 | It supports the following commands:
|
|---|
| 26 | .PP
|
|---|
| 27 | .nf
|
|---|
| 28 | .ta 0.5i 0.95i
|
|---|
| 29 | (.) a: append
|
|---|
| 30 | (.,.) c: change
|
|---|
| 31 | (.,.) d: delete
|
|---|
| 32 | e: edit new file"
|
|---|
| 33 | f: print name of edited file"
|
|---|
| 34 | (1,$) g: global command
|
|---|
| 35 | (.) i: insert
|
|---|
| 36 | (.,.+1) j: join lines together
|
|---|
| 37 | (.) k: mark
|
|---|
| 38 | (.) l: print with special characters in octal
|
|---|
| 39 | (.,.) m: move
|
|---|
| 40 | (.,.) p: print
|
|---|
| 41 | q: quit editor"
|
|---|
| 42 | (.) r: read in new file
|
|---|
| 43 | (.,.) s: substitute
|
|---|
| 44 | (1,$) v: like g, except select lines that do not match
|
|---|
| 45 | (1,$) w: write out edited file
|
|---|
| 46 | .fi
|
|---|
| 47 | Many of the commands can take one or two addresses, as indicated above. The
|
|---|
| 48 | defaults are shown in parentheses. Thus \fIa\fR appends to the current
|
|---|
| 49 | line, and \fIg\fR works on the whole file as default.
|
|---|
| 50 | The dot refers to the current line.
|
|---|
| 51 | Below is a sample editing session with comments given following the # symbol.
|
|---|
| 52 | .PP
|
|---|
| 53 | .nf
|
|---|
| 54 | .ta 0.5i 2.5i
|
|---|
| 55 | ed prog.c # Edit prog.c
|
|---|
| 56 | 3,20p # Print lines 3 through 20
|
|---|
| 57 | /whole/ # Find next occurence of \fIwhole\fR
|
|---|
| 58 | s/whole/while/ # Replace \fIwhole\fR by \fIwhile\fR
|
|---|
| 59 | g/Buf/s//BUF/g # Replace \fIBuf\fR by \fIBUF\fR everywhere
|
|---|
| 60 | w # Write the file back
|
|---|
| 61 | q # Exit the editor
|
|---|
| 62 | .fi
|
|---|
| 63 | \fIEd\fR is provided for its sentimental value.
|
|---|
| 64 | If you want a line-oriented editor, try \fIex\fR.
|
|---|
| 65 | If you want a good editor, use \fIelle\fR, \fIelvis\fR, or \fImined\fR.
