NAME
bootlog - write stdout/stderr of a program to file
SYNOPSIS
bootlog [-12ctar] logsize logfile program [arguments]
DESCRIPTION
bootlog is used to start a program and write stdout/stderr to a disk
file. This works also before mouning any file systems.
bottlog is designed to log the output of scripts/services at boot time,
before mounting any file system. This is typical for system init.
bootlog expects that when the program exits, the logfile is writable!
OPTIONS
-1 log only stdout
-2 log only stderr; default is to log stdout and stderr
-c create logfile
-t truncate logfile
-a append to logfile
-r replace old logfile with logfile~
logsize
maximal size of output to be logged
logfile
disk file name
program
the name of the program to start
arguments
additional arguments for program
WARNING
Use the option -c to force creating of the logfile.
Actually the options -c, -a, -t add O_CREAT, O_APPEND, O_TRUNC flags to
open(2) for logfile
EXAMPLE
bootlog -ctr 120000 /tmp/.sysinit.log /etc/rc.d/rc.sysinit
You will have the files /tmp/.sysinit.log and /tmp/.sysinit.log~
ENVIRON
bootlog uses the variable PATH to start program
If PATH is undefined it uses PATH=/bin:/usr/bin
