logsave - save the output of a command in a logfile

       Theodore Ts'o (tytso@mit.edu)

       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 logfilelogsave 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.

-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.
