Running script on 2.6 fails

Dear all,

I am right now working on understanding the 2.6 kernel BLOCK sbull
driver implementation provided in the Linux book 3rd Edition book.

I am OK with the block driver aspects. But, I am NOT able to run
sbull_load script to create the device NODES. When I tried running the
script, I failed saying

# sh sbull_load
: command not found
' bull_load: line 4: syntax error near unexpected token '{
' bull_load: line 4: '{

Can some one give an idea why is this failing?
Someone please help me in this aspect.You can see the script below ....

Regards,
Mukund Jampala

while (($part < $minors)); do

}

# FIXME: This isn't handling minors (partitions) at all.

# Remove stale nodes and replace them, then give gid and perms
