logsave [ -asv ] logfile cmd_prog [ ... ]
The logsave program will execute cmd_prog with the specified argu-
ment(s), and save a copy of its output to logfile. If the containing
directory for logfile does not exist, logsave will accumulate the out-
put 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 pro-
gram, logsave will take its input from standard input and save it in
logsave is useful for saving the output of initial boot scripts until
the /var partition is mounted, so the output can be written to
-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 con-
sole, while not being written to the log file.
-v This option will make logsave to be more verbose in its output
to the user.
