LinuxQuestions.org - Bootsplash - progress bar

The way I do it in slackware is create /etc/rc.d/rc.progress with:

Code:

#!/bin/sh

#

# rc.progress  This file has a common subroutine used to update a

#              bootsplash progress bar

#



# Count the number of times the progress bar is likely to be increased

num=$((`cat /etc/rc.d/rc.* | grep -c "^progressup"`))



function progressup(){

 progress=$((`cat /tmp/progressbar`));

 progress=$(($progress+1));

 echo $progress > /tmp/progressbar

 echo "show $(( 65534 * $progress / $num ))" > /proc/splash

}

Then at the top of each rc file you want to increase the bar in add:
# Load the splash function
. /etc/rc.d/rc.progress

At the end of rc.local add:
# Remove the temporary progress bar file
rm -f /tmp/progressbar

After that just add "progressup" to each file where you want the progress bar to increase (make sure it is at the start of a new line each time).

An example diff for rc.S in current is:
