    Hello,

    I have a bash script which runs perfectly in the shell. But when cron
    executes the same script it causes errors.

    if ( ! $SAV_INSTALL_PRG $SAV_INSTALL_OPTIONS 1>/dev/null )
    then
        echo "Unable to install the new engine"
        echo "Command: \"$SAV_INSTALL_PRG $SAV_INSTALL_OPTIONS\""
        LOG2SYSLOG "ERROR: Unable to install the new engine."
    else
        cd $TMP
        /bin/rm -rf $TMP/$TMP_SAV_INSTALL
        /bin/rm -f $IDE_DIR/*.ide
        LOG2SYSLOG "Successfully installed new sophos antivirus engine"
    fi

    All variables are defined in the header of this script.
    and LOG2SYSLOG looks like this:

    LOG2SYSLOG()
    {
        MY_NAME=`basename $0`
        MY_PID=`pidof -x $MY_NAME`

        logger -t "$MY_NAME[$MY_PID]" $1
    }

    The error message is this:

    Unable to install the new engine
    Command: "/tmp/sav-install/install.sh -ni"
    logger: invalid option -- n
    usage: logger [-is] [-f file] [-p pri] [-t tag] [-u socket] [ message
    ... ]

    I never call logger with a "n" option rather I call $SAV_INSTALL_PRG
    with an "n" option.
    I dont see why logger get the "n" option...

    Does anyone see the error?
    Thank you for your efforts.
