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