The ed editor
|
|
|
|
|
|
There's two modes in the editor: the input
|
|
mode and the command mode. While in the input
|
|
mode, what you type is added to the file
|
|
you're editing. While in command mode, you
|
|
can view or make modifications to the file.
|
|
|
|
To edit a new file called joe.c you would
|
|
type "ed joe.c", which puts you right into
|
|
input mode. You'd then write whatever code
|
|
you want. When finished, on a blank line you
|
|
would enter a single period, then hit enter.
|
|
This exits from input mode and puts you in
|
|
command mode.
|
|
|
|
When in command mode, you can modify the
|
|
file (like deleting lines, for example),
|
|
exit without saving your code, or exit and
|
|
save the code. To delete line 1, you'd hit
|
|
"1d" while in command mode.
|
|
To add a line after line 5, you'd hit
|
|
"5a", which would put you in input mode
|
|
right after line 5. To replace line 5 you'd
|
|
"5c" while in command mode.
|
|
|
|
For a full list of commands available in
|
|
command mode, hit "h" and enter while in the
|
|
editor command mode.
|
|
|
|
To exit the editor and save the file
|
|
as modified, issue the "x" command at
|
|
the editor. To exit without saving,
|
|
use "Q".
|
|
|
|
For your new object to be loaded into memory,
|
|
you must update it after you've edited it.
|
|
"update joe.c" will load the changes into memory.
