<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>logsave</B>
|
|
|
|
program will execute
|
|
<I>cmd_prog</I>
|
|
|
|
with the specified argument(s), and save a copy of its output to
|
|
<I>logfile</I>.
|
|
|
|
If the containing directory for
|
|
<I>logfile</I>
|
|
|
|
does not exist,
|
|
<B>logsave</B>
|
|
|
|
will accumulate the output in memory until it can be written out.
|
|
A copy of the output will also be written to standard output.
|
|
<P>
|
|
|
|
If
|
|
<I>cmd_prog</I>
|
|
|
|
is a single hyphen ('-'), then instead of executing a program,
|
|
<B>logsave</B>
|
|
|
|
will take its input from standard input and save it in
|
|
<I>logfile</I>
|
|
|
|
<P>
|
|
|
|
<B>logsave</B>
|
|
|
|
is useful for saving the output of initial boot scripts
|
|
until the /var partition is mounted, so the output can be written to
|
|
/var/log.

<H2>OPTIONS</H2>
|
|
|
|
<DL COMPACT>
|
|
<DT id="1"><B>-a</B>
|
|
|
|
<DD>
|
|
This option will cause the output to be appended to
|
|
<I>logfile</I>,
|
|
|
|
instead of replacing its current contents.
|
|
<DT id="2"><B>-s</B>
|
|
|
|
<DD>
|
|
This option will cause
|
|
<B>logsave</B>
|
|
|
|
to skip writing to the log file text which is bracketed with a control-A
|
|
(ASCII 001 or Start of Header) and control-B (ASCII 002 or Start of
|
|
Text). This allows progress bar information to be visible to the user
|
|
on the console, while not being written to the log file.
|
|
<DT id="3"><B>-v</B>
|
|
|
|
<DD>
|
|
This option will make
|
|
<B>logsave</B>
|
|
|
|
to be more verbose in its output to the user.
