.SH NAME
logsave \- save the output of a command in a logfile
.SH SYNOPSIS
.B logsave
[
.B \-asv
]
.I logfile cmd_prog [ ... ]
.SH DESCRIPTION
The
.B logsave
program will execute
.I cmd_prog
with the specified argument(s), and save a copy of its output to
.IR logfile .
If the containing directory for
.I logfile
does not exist,
.B logsave
will accumulate the output in memory until it can be written out.
A copy of the output will also be written to standard output.
.PP
If
.I cmd_prog
is a single hyphen ('-'), then instead of executing a program,
.B logsave
will take its input from standard input and save it in
.I logfile
.PP
.B logsave
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.
.SH OPTIONS
.TP
.B \-a
This option will cause the output to be appended to
.IR logfile ,
instead of replacing its current contents.
.TP
.B \-s
This option will cause
.B logsave
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.
.TP
.B \-v
This option will make
.B logsave
to be more verbose in its output to the user.
