I'm trying to write a python wrapper around wget to show the progress bar on a gui application.

blogd
BLOGD(8) The SuSE boot concept BLOGD(8)NAME
blogd - boot logging on /dev/console
SYNOPSIS
/sbin/blogd [/dev/realtty]
DESCRIPTION
Without argument blogd determines the real underlying character device of /dev/console. blogd spawns a pty/tty pair to reconnect the cur-
rent /dev/console with the slave of the pty/tty pair. During writing information from this slave to the real character device a ring buffer
is used to hold the information for writing it to an existing logging file.
To fetch the real tty of /dev/console the program showconsole(8) can be used. This has the advantage that blogd will not hold the real
character device of /dev/console as its controlling tty (would hangup any running getty on that character device).
SIGNALS
blogd knows a few signal to contol its behavior.
SIGQUIT, SIGINT, and SIGTERM
will cause blogd tries to write out the ring buffer and to exit.
SIGIO says blogd that now it is able to write on /var/log/boot.msg which means that the file system is mounted read/write and the kernel
messages are written to that file.
SIGSYS says blogd that it should stop writing to disk but continue to repeat messages to the old devices of the system console.
BUGS
blogd needs a mounted /proc and /dev/pts file system and tries to set the controlling tty to stdin if the real character device of
/dev/console is not given. After reading /proc blogd tries to restore the status of the controlling tty to avoid problems with getty pro-
cesses. This can fail because blogd forks to run in the background as a daemon.
FILES
/proc/<pid of blogd>/stat
the stat file of the blogd process.
/dev/console
the system console.
/var/log/boot.msg
logging file which is created by klogd(8) or dmesg(8).
