thanks Kevin for reply.
I want to create a slackware usb-installer disk, with usbimg2disk.sh
I create a disk with command:
$ qemu-img create slackware64-current-udisk.img 8G
then in slackware source directory:
$ sudo ./usbimg2disk.sh -i usbboot.img -o slackware64-current-udisk.img
report error like this:
*** Not a block device:
'/home/jaloo/qemu/slackware64-current/slackware64-current-udisk.img' !
in usbimg2disk.sh
# Sanity checks:
if [ ! -b $TOWIPE ]; then
echo "*** Not a block device: '$TOWIPE' !"
exit 1
fi
so my question is how to create a block device for Bash Conditional
Expression:
if -b
-b file
True if file exists and is a block special file.
