This is a quick and dirty program intended to rename /RAM5 at
|
||||
boot time.
|
||||
|
||||
See the man page for details.
|
||||
|
||||
If you decide to launch this program automatically from ProSel-16
|
||||
(as I do), ensure you change the file type to S16, otherwise ProSel
|
||||
will always prompt you when it is done ... most annoying.
|
||||
|
||||
This program is in the public domain.

|

.SH NAME
|
||||
renram5 \- rename /RAM5 at boot time
|
||||
.SH SYNOPSIS
|
||||
.BR renram5
|
||||
[
|
||||
.B \-d
|
||||
] [
|
||||
.I oldvolume
|
||||
[
|
||||
.I newvolume
|
||||
]]
|
||||
.SH DESCRIPTION
|
||||
.BR renram5
|
||||
is intended to be run automatically at boot time. It renames
|
||||
the volume
|
||||
.I oldvolume
|
||||
to
|
||||
.IR newvolume ,
|
||||
if
|
||||
.I newvolume
|
||||
does not already exist. If
|
||||
.I oldvolume
|
||||
or
|
||||
.I newvolume
|
||||
aren't specified, they default to
|
||||
.BR /RAM5
|
||||
and
|
||||
.BR /tmp .
|
||||
.LP
|
||||
If you are running
|
||||
.BR renram5
|
||||
automatically from ProSel-16 (and perhaps other launchers) you should
|
||||
change the filetype to
|
||||
.BR S16 .
|
||||
This will keep ProSel from prompting after the program is finished.
|
||||
When run as a
|
||||
.BR S16
|
||||
program, no command line arguments are possible.
|
||||
.SH OPTIONS
|
||||
.IP \fB-d\fP
|
||||
Enable debugging information.

/*

* renram5
|

*
|
||||
* This program is intended to be launched during boot time. It
|
||||
* renames the volume /RAM5 to /tmp if /tmp does not already exist.
|
||||
*
|
||||
* It can also be invoked as a shell command (in which it should
|
||||
* be changed to an exec file rather than a s16 file). As a shell
|
||||
* command, its usage is:
|
||||
* renram5 [-d] [ oldname [newname]]
|
||||
*
|
||||
* If <oldname> is not specified, it defaults to "/RAM5". If <newname> is
|
||||
* not specified, it defaults to "/tmp". The -d flag enables debugging
|
||||
* output.
|
||||
*
|
||||
* You probably need GNO/ME libraries in order to link this program.
