problem with udev

Hi,
When i turn the following script

Code:

    #!/bin/sh



    DEPMOD=`which depmod`

    UDEVCTRL=`which udevcontrol`

    UDEVADM=`which udevadm`



    install -D -m 700 usbcanII.ko /lib/modules/`uname -r`/kernel/drivers/usb/misc/usbcanII.ko

    install -m 700 usbcanII.sh /usr/sbin/

    if [ -d /etc/hotplug ] ; then

      install -m 777 usbcanII/usbcanII /etc/hotplug/usb/ ;

      install -m 644 usbcanII/usbcanII.usermap /etc/hotplug/usbcanII.usermap

    fi

    install -m 644 ../10-kvaser.rules /etc/udev/rules.d



    if [ `udevd --version` -lt 128 ] ; then

      $UDEVCTRL reload_rules ;

    else

      $UDEVADM control --reload-rules ;

    fi



    $DEPMOD -a

    if [ "$?" -ne 0 ] ; then

      echo Failed to execute $DEPMOD -a

    fi

i have theses problems

Code:

    [root@raspberrypi usbcanII]# ./installscript.sh

    which: no udevd in (/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/bin)

    ./installscript.sh: line 15: udev: command not found

    ./installscript.sh: line 15: [: -lt: unary operator expected

    [root@raspberrypi usbcanII]# which udev

    which: no udev in (/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/bin)

    [root@raspberrypi usbcanII]# PATH=/lib/udev/:$PATH

    [root@raspberrypi usbcanII]# ./installscript.sh

    which: no udevcontrol in (/lib/udev/:/lib/:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/bin)

As udevd version <> 128 i made the following changes

Code:

  #!/bin/sh



    DEPMOD=`which depmod`

    #UDEVCTRL=`which udevcontrol`

    UDEVADM=`which udevadm`



    install -D -m 700 usbcanII.ko /lib/modules/`uname -r`/kernel/drivers/usb/misc/usbcanII.ko

    install -m 700 usbcanII.sh /usr/sbin/

    if [ -d /etc/hotplug ] ; then

      install -m 777 usbcanII/usbcanII /etc/hotplug/usb/ ;

      install -m 644 usbcanII/usbcanII.usermap /etc/hotplug/usbcanII.usermap

    fi

    install -m 644 ../10-kvaser.rules /etc/udev/rules.d



  # if [ `udevd --version` -lt 128 ] ; then

    # $UDEVCTRL reload_rules ;

  # else

      $UDEVADM control --reload-rules ;

  # fi



    $DEPMOD -a

    if [ "$?" -ne 0 ] ; then

      echo Failed to execute $DEPMOD -a

    fi

but i noticed something what happens if /etc/hotplug doesn't exist ?? is it normal ? because for my situation it doesn't exist
