Text Editors
There are three text editors resident on the RTM3205 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.
joe
is the recommended editor for all purpose use in configuring and monitoring the
RTM3205. 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 started by simply issuing the command
joe [file-to-edit]
, optionally
with a file name to edit. It is the modern replacement for
edit
(see below).
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
introduced, they fell into this category and the
edit
text editor was appropriate. Now it is included
on the RTM3205 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.
elvis
is a full-featured
vi
clone which is provided in the RTM3205 file system for masochis-
tic Unix diehards. It is not the least bit user friendly to anyone lacking experience with text mode
applications. 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 RTM3205 - 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.
