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
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
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.
This option will cause the
output to be appended to logfile, instead of
replacing its current contents.
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
This option will make logsave to be more verbose
in its output to the user.
