Text Editors
There are three text editors resident on the Sonoma file system:
edit
,
joe
and
elvis
. All of these
may be useful when needing to edit system configuration files or to view and search within system
log files.
edit
is a very simple editor with Wordstar key commands that was originally developed for
extremely memory-limited environments, such as floppy boot disks and embedded Linux appliances.
When EndRun Technologies’ first generation Linux-based embedded network time servers were in-
troduced, they fell into this category and the
edit
text editor was appropriate. Now it is included on
the Sonoma file system for legacy reasons, since it has been the default editor for all first and second
generation EndRun Technologies products. A man page for
edit
is resident on the system. When
it is first started, and you did not give it a file name to edit on the command line, it shows a start-up
screen with its command syntax, But once you have opened a file to edit, online help is not available.
It is started by issuing the command
edit [file-to-edit]
, optionally with a file name to edit.
joe
is the modern replacement for
edit
on the Sonoma. It is a full-featured editor with
syntax highlighting and is also based on the Wordstar commands. It is user friendly with easy to find
help for its key commands, and complete man page documentation. It is the recommended editor for
all purpose use in configuring and monitoring the Sonoma time server. It is started by simply issuing
the command
joe [file-to-edit]
, optionally with a file name to edit.
elvis
is a full-featured
vi
clone which is provided in the Sonoma file system for masochistic
Unix diehards. It is not the least bit user friendly to anyone lacking experience with text mode ap-
plications. If you don’t know what
vi
is, avoid using this editor! It is started by simply issuing the
command
vi [file-to-edit]
, optionally with a file name to edit.
Change Log-In
Banners
There are three different log-in banners in the Sonoma - the serial port banner, the Telnet banner, and
the SSH banner. You must be logged in as the “root” user in order to edit the
rc.local
file and change
the log-in banners. Perform the following:
edit /etc/rc.d/rc.local
Change the banners as appropriate. After saving the file, copy it to
/boot/etc
like this:
cp -p /etc/rc.d/rc.local /boot/etc/rc.d
Then reboot for your changes to take effect.
