RFC: cleaner version of test.block

[Chris Friesen <chris_friesen@sympatico.ca>]

I propose the following version of test.block.  I think the code's
easier to read than the one using "cut", and it removes the dependency
on stuff outside of bash.

Also, running the call to udev backgrounded makes the whole scan take 1
second, rather than 1 second for each entry.

Chris





#!/bin/sh
#
# test.block - run udev(8) on each block device in /sys/block

SYSFSDIR=/sys           # change this for a nonstand sysfs mount point
BIN=./udev              # location of your udev binary
export ACTION­d       # 'add' or 'remove'


for i in ${SYSFSDIR}/block/*; do
         # add each drive
         export DEVPATH=${i#${SYSFSDIR}}
         $BIN block &

         # add each partition, on each device
         for j in $i/*; do
                 if [ -f $j/dev ]; then
                         export DEVPATH=${j#${SYSFSDIR}}
                         $BIN block &
                 fi
         done
done
